InSAR decorrelation to assess and prevent volcanic risk
EUROPEAN JOURNAL OF REMOTE SENSING
Autore/i: Malinverni, Eva Savina; Sandwell David, T.; Tassetti Anna, N.; Cappelletti, Lucia
Classificazione: 1 Contributo su Rivista
Abstract: SAR has several strong key features: fine spatial resolution/precision and high temporal pass frequency. Moreover, the InSAR technique allows the accurate detection of ground deformations. This high potential technology can be invaluable to study volcanoes: it provides important information on pre-eruption surface deformation, improving the understanding of volcanic processes. As a downside, SAR measurements are influenced by artifacts such as atmospheric effects or bad topographic data. Correlation gives a measure of these interferences, quantifying the similarity of the phase of two SAR images. Different approaches exist to reduce these errors but the main concern remains the possibility to correlate images with different acquisition times: snow-covered or heavily-vegetated areas produce seasonal changes on the surface. Working with images with very fast acquisition time partly limits decorrelation. Though, images with a short temporal baseline aren't always available and some artifacts affecting correlation are time-independent. This work studies correlation of pairs of SAR images focusing on the influence of surface and climate conditions, especially snow coverage and temperature. Furthermore, the effects of the acquisition band on correlation are taken into account, comparing L-band and C-band images. All the chosen images cover most of the Yellowstone caldera (USA) over a span of 4 years, sampling all the seasons. Interferograms and correlation maps are generated. To isolate temporal decorrelation, pairs of images with the shortest baseline are chosen. Correlation maps are analyzed in relation to snow depth and temperature. Results obtained with ENVISAT and ERS satellites (C-band) are compared with the ones from ALOS (L-band). Results show a good performance during winter and a bad attitude towards wet snow (spring and fall). During summer both L-band and C-band maintain a good coherence with L-band performing better over vegetation.

DEM automatic extraction on Rio de Janeiro from WV2 stereo pair images
IOP CONFERENCE SERIES. EARTH AND ENVIRONMENTAL SCIENCE
Autore/i: Malinverni, Eva Savina
Classificazione: 1 Contributo su Rivista
Abstract: The use of three-dimensional data has become, for a lot of mapping applications, very important. DEM are applied for modelling purposes, i.e. the 3D city model generation, but principally for imagery orthorectification. In aerial photogrammetry is well known the suitable use of stereo imagery to produce an accurate DEM, but the limits of the process (cost, schedule of data collection, highly technical staff) and the new advanced digital image processing algorithms have open the work scenario to the remote sensing data. This research has wanted to investigate the possibility to obtain accurate DEMs by means of automatic terrain extraction algorithms implemented in Leica Photogrammetry Suite (LPS) from stereoscopic remote sensing images collected by DigitalGlobe’s WorldView-2 (WV2) satellite. The DEM of Rio de Janeiro (Brazil) and the correspondent digital orthoimages have been the results.

Abstract: The main goal of the SIT-REM project is the design and the development of an interoperable web-GIS environment for the information retrieval and data editing/updating of the geobotanical and wildlife map of Marche Region. The vegetation, plant landscape and faunistic analysis allow the realization of a regional information system for wildlife-geobotanical data. A main characteristic of the SIT-REM is its flexibility and interoperability, in particular, its ability to be easily updated with the insertion of new types of environmental, faunal or socio-economic data and to generate analyses at any geographical (from regional to local) or quantitative level of detail. Different query levels obtain the latter: spatial queries, hybrid query builder and WMSs usable by means of a GIS. SIT-REM has been available online for more than a year and its use over this period has produced extensive data about users' experiences.. © 2014 by the authors; licensee MDPI, Basel, Switzerland

Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: In an attempt to stop the degradation of the Complejo Arqueologico Chan Chan, the Peruvian government, pressed by UNESCO, in 2000 approved the Plan Maestro de conservación y manejo, redact by Instituto Nacional de Cultura, (today Ministerio de Cultura). The Plan Maestro has a number of projects and sub-projects aimed to enhancing the complex and its territory with the purpose of helping the socio - economic development of the population. The MIPE intends to support the actions foreseen by the Plan Maestro participating to its revision and updating and following three main objectives: the planning of the Archaeological Park of Chan Chan, the restoration and the virtual visit of Palacio Rivero and other peculiar architectonic typologies and the baking of local handicraft and tourism by mean of training courses arranged also with the help of the international cooperation. In order to achieve these objectives, taking into account the impressive dimensions of the site, it was very important to take advantage of the potentiality of new methodologies of investigation: the remote sensing techniques and the ICT processes to organize and archive the geodatabase; the modern acquisition techniques, such as laser scanner, to arrange a 3D surveying, to reconstruct in virtual way the emergencies and by means other multimedia solutions to spread the whole site by virtual visits.

Autore/i: F., Colosi; R., Gabrielli; R., Orazi; Malinverni, Eva Savina
Classificazione: 1 Contributo su Rivista
Abstract: Since 2002, the Italian Mission of CNR-ITABC has been operating in the archaeological complex of Chan Chan (Peru), which is the largest pre-Columbian settlement entirely built with adobe. In 1989 Chan Chan was placed on the UNESCO World Heritage List. The main purpose of the work is aimed at the conservation, documentation and use of the site and of the territory that is related to Chan Chan from a historical and cultural point of view. The urban structure of Chan Chan, which is spread over a surface of 14 km2, has a number of buildings which characterizes the town at both an architectural (ciudadelas, huacas, huachaques) and decorative level (bas-reliefs, geometrical motifs). In order to achieve our research goals, we had to arrange for the combined use of various analysis techniques that would provide both urban and architectural information about the town. The data we obtained allowed us to make a more up-to-date interpretation of the urban fabric and revealed intriguing details regarding the construction phases of one of its palaces which will be helpful both for the planning of the Archaeological Park and the restoration project of the Palacio Rivero.

Autore/i: Fangi, Gabriele; Malinverni, Eva Savina; A. N., Tassetti
Classificazione: 1 Contributo su Rivista
Abstract: The Università Politecnica delle Marche is charged of the study, survey and documentation of the Chan towers in Vietnam. The towers are spread near the coastline from latitude 16° 30’, to latitude of 10° 56’. The Champa civilization flourished from 8th century till 17th century produced the Cham towers, places of religious worship. The ancient Cham people created a developed culture expressed in the architecture in the towers, which were Buddhist temples. Roughly there are six different architectonic styles and two different layouts in plan. One lay-out is that one main tower is surrounded by smaller service buildings, like walls, doors, gates; the other layout is a set of three aligned towers. We carried out the documentation with three different techniques, laser scanning, dense point clouds generation with SfM (Structure from Motion) algorithm, and mainly by Panoramic Spherical Photogrammetry (PSP). Laser scanning is indeed the best instrument but sometimes its availability is very limited for different practical and logistic reasons. The point cloud generation produced good results, but it has some problems and limitations of management too. On the other hand PSP is very quick technique in the taking phase, but the restitution is rather slow. PSP is suitable for a good metric documentation, making the Cham tower project the main project of documentation executed with spherical photogrammetry.

Autore/i: A. L., DE AMORIM; Fangi, Gabriele; Malinverni, Eva Savina
Editore: Grussenmeyer P.
Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: The Cultural Heritage disappears at a rate higher than we are able, not only, to restore but also to document: human and natural factors, negligence or worst, deliberate demolitions put in danger the collective Architectural Heritage (AH). According to CIPA statements, the recording is important and has to follow some guidelines. The Architectural and Urban Heritage data have to be historically related, critically assessed and analyzed, before to be organized according to a thematic structure and become available for further uses. This paper shows the experiences developed by the Laboratory of Computer Graphics applied to Architecture and Design (LCAD), at the Architecture School of the Federal University of Bahia (FAUFBA), Brazil, in cooperation with the Università Politecnica delle Marche (UNIVPM, DICEA Department), Italy, in documenting architectural heritage. The research set up now has been carried out in the historical sites of Bahia, as Pelourinho neighborhood, a World Heritage by UNESCO. Other historical sites are in the plan of this survey, like the cities of Lençóis and Mucugê in Chapada Diamantina region. The aim is to build a technological platform based on low cost digital technologies and open source tools, such as Panoramic Spherical Photogrammetry, Spatial Database, Geographic Information Systems, Three-dimensional Geometric Modeling, CAD technology, for the collection, validation and dissemination of AH.

Road pavement crack automatic detection by MMS images
21st Mediterranean Conference on Control and Automation-MED 2013
Autore/i: Mancini, Adriano; Malinverni, Eva Savina; Frontoni, Emanuele; Zingaretti, Primo
Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: The research topic was to test different feature extraction methods to localize road pavement cracks useful to construct a spatial database for the pavement distress monitoring. Several images were acquired by means of a line scan camera that assembled in a Mobile Mapping System (MMS) allows tracking directly the position of the images by a GPS-INS system. Following an automatic digital image processing was performed by means of several algorithms based on different approaches (edge detection and fuzzy set theory). The detected cracks were described with some parameters in relation to some shape characteristics (dimension, typology, direction), which are necessary to recognize the gravity of the road pavement conditions. The edge detection techniques tested in this research allowed identifying fatigue cracking or alligator cracking and also thin linear cracks in images with strong radiometric jumps by applying filters, gradient functions and morphological operators. The snake approach was one of them, in particular the type called Gradient Vector Flow (GVF). Another approach was based on the fuzzy theory. The advantage of this method is that the pixels, necessary to identify the cracks in road pavement, are darker than their surroundings in an image. The last stage was the pavement distress spatial database collection. The Mobile Mapping System (MMS) has allowed localizing the raster data and consequently the vector features of the detected cracks, associating into the table their attributes too. The proposed approaches allow to automatically localize and classify the kind of road pavement crack.

Abstract: The research aim is to 3D structure and organize a numeric cartography for GIS and turn it into CityGML standardized features. The work is framed around a first phase of methodological analysis aimed to underline which existing standard (like ISO and OGC rules) can be used to improve the quality requirement of a cartographic structure. Subsequently, from this technical specifics, it has been investigated the translation in formal contents, using an owner interchange software (SketchUp), to support some guide lines implementations to generate a GIS3D structured in GML3. It has been therefore predisposed a test three-dimensional numerical cartography (scale 1:500, generated from range data captured by 3D laser scanner), tested on its quality according to the previous standard and edited when and where necessary. Cad files and shapefiles are converted into a final 3D model (Google SketchUp model) and then exported into a 3D city model (CityGML LoD1/LoD2). The GIS3D structure has been managed in a GIS environment to run further spatial analysis and energy performance estimate, not achievable in a 2D environment.

Abstract: Il lavoro proposto vuole ottimizzare una metodologia di documentazione dell’architettura che, a partire dalle fotografie panoramiche, si misura di volta in volta con gli strumenti e le tecnologie a disposizione per proporre una soluzione integrata, speditiva e low-cost di Virtual Architecture. La tecnica sviluppata nasce in un contesto di ricerca più ampio che da anni studia la possibilità di usare le immagini panoramiche sferiche per il rilievo metrico dell’architettura (Fangi, 2007-2012). I dati a disposizione (panoramiche orientate), l’affidabilità raggiunta e metodi di Image-based Modeling (d’Annibale, 2009-2011) sono alla base della proposta di una tipo di ricostruzione 3D integrata ed estremamente flessibile: dal rilievo professionale del patrimonio culturale alla sua comunicazione nei musei virtuali. La soluzione proposta si sviluppa tramite l’integrazione e implementazione di diverse tecniche (Fotogrammetria Sferica, Structure From Motion, Image-based Modeling) e si pone l’obiettivo di raggiungere alti livelli di precisione metrica del rilievo e resa fotorealistica dei modelli ricostruiti. L’intera procedura risulta essere accessibile grazie alla scelta di utilizzare strumenti low-cost e adattabile allo scopo finale.

Change Detection applying Landscape Metrics on High Remote Sensing Images
PHOTOGRAMMETRIC ENGINEERING AND REMOTE SENSING
Autore/i: Malinverni, Eva Savina
Classificazione: 1 Contributo su Rivista
Abstract: Haiti earthquake produced a big effort in the remote sensing data collection. Many international surveying organizations were involved to collect, process and use the spatial information to rescue the population. Here I illustrate a change detection methodology based on landscape metrics, derived by the landscape ecology and implemented in FRAGSTAST software. Some of these metrics were applied to Pre and Post event classified images (Quickbird and IKONOS). The attention was focused on 10 test areas, characterized by different spatial patterns and urban structures. The land cover classification (Urban and Other) was provided by an unsupervised K-Means algorithm in ILWIS open source software. The final results and their temporal comparison have allowed to localize the earthquake damages and the occurred changes, also analyzing the fragmentation of the urban morphology. The GIS management of the information have improved the thematic map production, resulting very useful for the damage assessment.

Hybrid Object-based Approach for Land Use /Land Cover Mapping using High Resolution Imagery
INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE
Autore/i: Malinverni, Eva Savina; Tassetti, A. N.; Mancini, Adriano; Zingaretti, Primo; Frontoni, Emanuele; Bernardini, A.
Classificazione: 1 Contributo su Rivista
Abstract: Traditionally, remote sensing has employed pixel-based classification techniques to deal with Land Use/Land Cover (LULC) studies. Generally, pixel-based approaches have been proven to work well with low spatial resolution imagery (e.g., Landsat or System Pour L’Observation de la Terre (SPOT) sensors). Now, however, commercially available high spatial resolution images (e.g., aerial Leica ADS40 and Vexcel UltraCam sensors, and satellite IKONOS, Quickbird, GeoEye and WorldView sensors) can be problematic for pixel-based analysis due to their tendency to oversample the scene. This is driving research towards object-based approaches. The paper proposes a hybrid classification method with the aim of incorporating the advantages of supervised pixel-based classification into object-based approaches. The method has been developed for medium scale (1:10.000) LULC mapping using ADS40 imagery with 1 m Ground Sampling Distance (GSD). First, spatial information is incorporated into a pixel-based classification (AdaBoost classifier) by means of additional texture features (Haralick, Gabor, Law features), which can be selected “ad hoc” according to optimal training samples (“Relief-F” approach, Mahalanobis distances). Then a rule-based approach sorts segmented regions into thematic CORINE Land Cover (CLC) classes in terms of membership class percentages (a modified Winner-Takes-All approach) and shape parameters. Finally, ancillary data (roads, rivers, etc.) are exploited to increase classification accuracy. The experimental results show that the proposed hybrid approach allows the extraction of more LULC classes than conventional pixel-based methods, while improving classification accuracy considerably. A second contribution of this paper is the assessment of classification reliability by implementing a stability map, in addition to confusion matrixes.

Abstract: The most extensive use of Remote Sensing data is in land cover/land use (LCLU) studies by means of automated image classification. The general objective of this research is to develop an automatic pixel-based classification methodology with the aim to produce a Regional land use map congruent with the CORINE Land Cover legend. Starting point are detailed ground data, already gathered fostering interoperability among several Regional bodies’ DBs and high resolution multi-spectral IKONOS imagery. In the light of land mapping, there are two main features related to IKONOS imagery: lack of spectral information (4 spectral bands) and high spectral variability (high spatial resolution). This results in problems in terms of class information extraction especially using pixel-based image classification methods in which spatial information existing between a pixel and its neighbours is not used. To overcome these deficits, the use of vegetation indexes (NDVI feature and TDVI masks) and texture (GLCM and edge-density features) is investigated with respect to its impact on land cover/land use classification. The developed spectral/textural classification schema is compared with the classical approach using only spectral information. An accuracy assessment is carried out which shows that image data with 4 IKONOS spectral bands plus NDVI band plus 6 texture bands achieve an accuracy of 80.01% compared to 63.44% of accuracy achieved by using the few spectral bands only. Furthermore it allows the discrimination of 10 CLC classes. Experimental results show how, starting from available but also binding data (IKONOS imagery and available Regional ground data), a classification schema can be developed with enhanced performance and strong relation to the specific setup.

Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: A Land Cover/Land Use (LCLU) Information System is proposed as a new dynamic and flexible approach to describe landscape objects. It is able to give a deeper and more realistic thematic description by storing membership land cover attributes for each polygon automatically extracted and classified by the T-MAP software. The proposed approach can overcome the traditional “hard” classification by taking directly into account “fuzzy” cover components and making the classification approach more bounded with the polygon characteristics and their changes. The LCLU Information System can be easily integrated with different databases, making it suitable for different nomenclatures and further analysis, regarding environmental indexes, class updating and classification stability assessment

Classificazione: 1 Contributo su Rivista
Abstract: The choice of the best classification approach for thematic map generation relies on many factors, such as image resolution and minimum mapping unit. The generalized GIS-ready products derived from the results of pixel-based approaches and the availability of higher resolution imagery have directed research towards object-based classification approaches. In this paper we present the superior performance of a hybrid methodology that combines the results of automatic segmentation with the land cover information derived from a pixel classification by means of the Winner Takes All (WTA) algorithm. Land use and land cover results obtained through this hybrid classification approach are compared with those of a One Against All (OAA) object-oriented classification approach.

Abstract: Recently, there is an increasing demand for information on actual land use/land cover (LU/LC) from planning, administration and scientific institutions. Remote sensing combined with GIS tools can give quick reply providing timely information products in different geometric and thematic scales. Anyway the effort to make the land use map by visual interpretation is still very high and cannot keep up with the development pace. On the other side automatic procedures do not assure to follow detailed and well- structured land use nomenclature if it is not performed by a customized learnig system. This new approach is required to incorporate automated image classification to human image understanding. In this context the here proposed T-MAP application combines segmentation tools with an hybrid classification technique (a rather new trend in image classification) and a rule-based thematic categorization depending on information both at pixel and object level. Its rule-based system lets the user define thematic assignments by building rules based on feature attributes (i.e. membership cover class percentage, confusion index, etc.) and on landscape analysis (spatial metrics and pattern indicators), taking, in this way, also advantage of the human land use understanding. The output is a thematic map characterized by a custom-designed legend and a reasonable performance in terms of accuracy, number of extractable classes and legend detail.

Abstract: This work is part of a wider project whose general objective is to develop an automatic classification methodology, congruent with the CORINE land-cover thematic legend, by high resolution multi-spectral IKONOS images datasets. The imagery were provided by Regione Marche institution thanks to a research agreement signed together with the Technical University of Marche jointed departments (DARDUS, DIIGA and DiSASC). According to a hierarchical approach, different phases exist for image classification. At the lowest level classification was merely based on specific pixels spectral value, while moving toward highest levels, segmentation methodology can be used according to features spatial pattern to perform better results. The present paper aims to deepen the first of the above mentioned hierarchical levels. The methodological approach focus on the optimal selection criteria, in order to define the best setting (spectral bands, Ground Truth, etc.) for the training stage. With this intent different supervised classification algorithms have been tested. In particular, the training stage was carried out tacking advantage of a dedicated-GIS platform implementation. Each Ground Truth sample was collected by means of specific campaign and/or pan-sharpened IKONOS dataset visual interpretation. The depicted classes were grouped in different levels of increasing detail. To be more confident, the CORINE standard legend has been modified according to current study case specificity, in order to obtain an optimal distribution of the samples in the training set. This also allowed to improve the training stage setting by excluding clusters whose spectral values largely ranging far from corresponding average class values.

Abstract: In the Northwestern Peru, near the city of Trujillo, an Italian Archaeological Mission (MIPE), in close collaboration with the INC (National Institute of Culture of Peru) is working on the site of Chan-Chan that is the widest archaeological complex in the world for the constructions in raw earth. The mission is carrying out a multidisciplinary survey with the aim of studying a methodology for the site maintenance and the creation of a local center of documentation. According to this wider project, the research goal here achieved and explained is based on a QUICKBIRD high resolution image analysis. Applying some image classification techniques it is possible to investigate the whole archaeological site, with the aim of a better definition of its general features and of a contribution to the exploitation of the surroundings.

Stability maps for really exploitable automatic classification results
17th International Conference on Geoinformatics
Autore/i: Frontoni, Emanuele; A., Bernardini; Malinverni, Eva Savina; Mancini, Adriano; Zingaretti, Primo
Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: The paper describes a new methodology for producing really exploitable results from automatic classification algorithms. The output of these algorithms is usually constituted by an image with each region assigned to one out of n classes. If the end user, on the basis of results obtained from a control set provided with a ground truth, simply knows that classification over the whole dataset can be considered correct at, for example, 85% (s)he cannot know where correct and erroneously classified regions are really located in the whole dataset. Obviously, the result obtained can be exploited to effectively compute global indexes over the dataset, but it cannot be used as a thematic map. Thus, in addition to the assignment of a class to each region we propose an approach that provides a stability map, a binary image that separates regions (S) classified with high accuracy from those (U) whose classification result should be verified before being used. Two further benefits derive from the construction of the stability map: the control set can be used to set up a good threshold for binarizing the stability map (that is, a threshold by which all regions S are effectively correctly classified); unreliable regions U can help the end user to identify principal causes of (types of regions leading to) misclassification and corresponding (fuzzy, neural, rule based, etc.) approaches to overcome them.

Abstract: This work is part of a wider project whose general objective is to develop a methodology for the automatic classification, based on CORINE landcover (CLC) classes, of high resolution multispectral IKONOS images. The specific objective of this paper is to describe a new methodology for producing really exploitable results from automatic classification algorithms. Input data are basically constituted by multispectral images, integrated with textural and contextual measures. The output is constituted by an image with each pixel assigned to one out of 15 classes at the second level of the CLC legend or let unclassified (somehow a better solution than a classification error), plus a stability map that helps users to separate the regions classified with high accuracy from those whose classification result should be verified before being used

Abstract: . This research developed a study process to analyze the status of some Alpine glacier groups (Adamello, Ortles-Cevedale and Bernina) localized in the North of Italy, the “water tower” of Eu-rope. The investigation was based on a set of multi-temporal three Landsat scenes acquired with the sensors MSS, TM and ETM+ combined with other types of information (2D, 3D and thematic data). The GIS based analysis, supported by remote sensing processing, allowed the extrapolation of the meaningful parameters for the glacier dynamism in the temporal displacement of observa-tion.

Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: The aim of this research is focused on the development of an Open Source platform that would provide a 3D interactive and flexible geo-visualization of spatial data coming from geographic information system (GIS). The application regards the cross-border spatial databases connecting the Prealpi Giulie Nature Park (Italy) and the Triglav National Park (Slovenia). Efficient methods were developed for data processing and data diffusion in a transnational Geo-portal by MapServer. To augment the realism of the product, from the bi-dimensional representation to the three-dimensional one, we adopted the Virtual GIS solution. The Virtual Reality in the GIS allows the visual data access in a 3D context and some real time performances. So in this project we had some opportunities to implements different scenarios improving the understanding of the landscape and allowing a virtual walk inside the park areas.

Abstract: La formazione di un sistema informativo territoriale 3D (SIT), dedicato alla formazione di un piano regionale per la qualità dell’aria in Regione Lombardia, è un esempio, interessante e significativo, di geomatica applicata al territorio. Le discipline del rilevamento, messe a disposizione di innumerevoli altre discipline, interessate allo studio di dati georeferenziati e solitamente dinamici ha portato a sviluppare nuovi ambiti applicativi. Le tecnologie dell’informazione fra le quali spiccano i sistemi informativi e l’informatica grafica hanno non solo favorito (ed imposto) il passaggio dall’analogico al digitale delle suddette tecniche, ma anche promosso l’avvento di nuove tecniche di rilievo e rappresentazione.

Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: National borders are becoming less and less important with integration of different regions to united European space. Spatial data are essential for management and development of regions by improving or establishing cross-border and transnational networks of spatial information. Spatial data are mostly organized and maintained within individual country in their national coordinate system. To improve management on crossborder and transnational level we need homogenized data. Our study presents homogenisation of spatial data at cross-border national park regions including Prealpi Giulie Nature Park and Triglav National Park. Homogenisation of spatial data was performed using GIS tools. One of the objectives of the study is to provide national park authorities and other regional actors with the manual and tools concerning homogenisation of spatial data. Thus general solution about homogenization in cross-border region is presented.

Abstract: The aim of this research concerns the construction,representation and generalization, in the GIS, of different map scales by standard procedure,preserving the correspondences and the data structures. This issue involves many different types of data structures and data manipulations. We define the data models suitable to describe the physical reality in the GIS (the topological and the vector model) and the spatial relationships to perform a correct use of a spatial database. The topic of this paper is to show how topological relations can be used to detect and to correct errors in GIS data sets. In the second part, in fact, we take into account the procedure to correct the topological inconsistency in the maps at different scale, moreover after the map generalization. To make more effectively the research we implemented a new tool in a commercial software, called Topology, applying to different kind of spatial databases.

Abstract: Abstract This paper addresses the use of HySenS airborne hyperspectral data for environmental urban monitoring. It is known that hyperspectral data can help to characterize some of the relations between soil composition, vegetation characteristics, and natural/artificial materials in urbanized areas. During the project we collected DAIS and ROSIS data over the urban test area of Pavia, Northern Italy, though due to a late delivery of ROSIS data only DAIS data was used in this work. Here we show results referring to an accurate characterization and classification of land cover/use, using different supervised approaches, exploiting spectral as well as spatial information. We demonstrate the possibility to extract from the hyperspectral data information which is very useful for environmental characterization of urban areas. Key words hyperspectral remote sensing – urban land use – vegetation distribution – classification

Abstract: In the last decade, the new technology of laser scanning has improved the architectural and archaeological survey. This instrument measures millions and millions of points in a short time. But the more interesting and above all more difficult goal is, up till now, the data processing. Using several procedures and testing some softwares it is possible to generate a 3D mesh with different resolution. It is useful when the single parts of the architectonic object present a variety of aspects. The triangles of the mesh can be decimated referring to planar surfaces without many details. On the contrary it will be necessary to refine the parts regarding decorations, bas-reliefs, statues and so on. This kind of procedures generates a 3D mesh easier to manage in the realization of a virtual reality scenario. Furthermore the textures applied at the same resolution too, allow to reconstruct the object faithfully and to explore it on the net on-line. The application regards a recent survey of the façade of the Ancona Dome by Mensi GS100 Laser Scanning

Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: The authors had the opportunity to collect, analyze and compare different kinds of representation acquired by means of ancient and modern technologies. The idea was born out after having found an ancient perspective, realized in the nineteenth century, by means of a camera lucida, in the Archive of Brera Observatory - Milan (Italy). To validate the accuracy of the panorama, i.e. the capability of this old technique, to obtain a good altimetric mapping, a modern terrestrial photogrammetric survey was set up and compared.

Missioni di geodesia spaziale per la determinazione del campo gravitazionale terrestre
BOLLETTINO DI GEODESIA E SCIENZE AFFINI
Autore/i: Albertella, A.; Malinverni, Eva Savina; Tornatore, V.
Classificazione: 1 Contributo su Rivista
Abstract: Tre missioni spaziali dedicate alla determinazione del campo di gravità terrestre su scala globale sono state recentemente inserite nei programmi di alcune tra le più importanti agenzie spaziali internazionali. I lanci dei satelliti relativi a ciascuna missione verranno effettuati nel giro di pochi anni già a partire dai primi mesi del 2000. Questo lavoro descrive i problemi legati alla misura dallo spazio del campo di gravità terrestre e illustra le soluzioni offerte da ciascuna missione. Inoltre presenta le ricadute e le possibili applicazioni in discipline quali la geodinamica, l’oceanografia, la climatologia e la geodesia stessa. Tali applicazioni saranno realizzabili grazie al raggiungimento di un obbiettivo, ormai molto vicino, comune a tutte e tre le missioni: la determinazione del campo di gravità terrestre con alta risoluzione e precisione uniforme su scale globale

Complex Surface Representation
International cooperation and technology transfer
Autore/i: Crippa, B.; Malinverni, Eva Savina; Tucci, G.
Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: In this paper we illustrate a method for automatic reconstruction of models of a piecewise smooth surface. When the object has a complex shape it is very difficult to obtain a good reconstruction and a real-looking representation. If the object has a continuos curvature (convex hull) it is possible to generate a 3D triangular surface employing the Delaunay algorithm, generalized to the 3d-dimensional case. Then if one wants to have a good result in terms of visual display it is necessary to apply another algorithm that produces Bézier splines on a triangular support. Of course, a realistic reconstruction of the object shape needs a high hardware performance to obtain as a final product the display of the interpolated surface (using CAD software). Some applications will be shown by means of examples.

Tecniche di validazione di dati territoriali qualitativi e quantitativi
BOLLETTINO DELLA SOCIETÀ ITALIANA DI TOPOGRAFIA E FOTOGRAMMETRIA
Autore/i: Bellone, T.; Malinverni, Eva Savina; Nocera, R.
Classificazione: 1 Contributo su Rivista
Abstract: Il controllo delle modificazioni territoriali ed ambientali cresce continuamente di importanza. I GIS si propongono come sistemi insostituibili in questo settore, per la varietà e la complessità dei dati di cui tengono conto e la capacità di aggiornamento. La validazione delle basi di dati viene effettuata mediante un’opportuna analisi delle differenze qualitative e quantitative tra i campioni ed i dati disponibili nelle basi di dati. Si definisce una procedura operativa che valuti opportuni indicatori statistici con i quali stabilire se le basi di dati sono attendibili, oppure se è necessario procedere al loro aggiornamento.

Moderne metodologie per il rilievo ed il controllo dell'assetto del territorio, la valutazione d'impatto ed il monitoraggio ambientale
BOLLETTINO DELLA SOCIETÀ ITALIANA DI TOPOGRAFIA E FOTOGRAMMETRIA
Autore/i: Bellone, T.; Malinverni, Eva Savina; Tarantola, S.
Classificazione: 1 Contributo su Rivista
Abstract: La presente nota si occupa dei moderni strumenti per il controllo dell'assetto del territorio, la valutazione d'impatto ed il monitoraggio ambientale. A tal fine, prende in considerazione questioni relative ai sistemi informativi territoriali ed all'elaborazione d'immagini digitali, come pure problemi d'analisi dei dati a referenza spaziale tempo-varianti e non. Un esempio reale di analisi multivariata vuole dare alla nota caratteristiche di concretezza (un sommario illustrativo sull'analisi di varianza serve da introduzione a queste importanti tecniche).
