It represents a step forward for both the accuracy and automation of LULC applications and allows users to setup thematic assignments through rules based on feature attributes and human expert interpretation of land usage. The synergy between different types of information means that LiDAR can give new hints at both the segmentation and hybrid classification steps, leading to a joint use of multispectral, spatial and elevation data. The output is a thematic map characterized by a custom-designed legend that is able to discriminate between land cover classes with similar spectral characteristics (level 3 of the CLC legend). Experimental results from a hilly farmland area with some urban structures (Musone river basin, Ancona, Italy) are used to highlight how the proposed methodology enhances land cover classification in heterogeneous environments.

3D image models in a dynamic environmental GIS / Eva Savina Malinverni (01/03/2003)

Public Titre : 3D image models in a dynamic environmental GIS Type de document : Article/Communication Auteurs : Eva Savina Malinverni, Auteur ; F. Di Gioia, Auteur Congrès : Visualization and animation of reality-based 3D Models (24 - 27 Février 2003; Tarasp-Vulpera, Suisse), Auteur Année de publication : 01/03/2003 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Photogrammétrie numérique [Termes descripteurs IGN] aménagement du territoire [Termes descripteurs IGN] base de données cartographiques [Termes descripteurs IGN] cartographie numérique [Termes descripteurs IGN] modèle numérique de terrain [Termes descripteurs IGN] orthoimage [Termes descripteurs IGN] représentation multiple [Termes descripteurs IGN] SIG dynamique [Termes descripteurs IGN] système d'information environnementale [Termes descripteurs IGN] visualisation 3D Résumé : (Auteur) The modem digital cartography, represented by numerical cartography, digital elevation models (DEM, DTM, DSM), orthoimages or the same like photo textured on DEM, is the metrically correct and highly descriptive system on which integrate any other source of information. These three-dimensional models in dynamic GIS can provide an interesting tool for the environmental and territorial data management. Aim of this research is to set up procedures for generating a three-dimensional map with maximum characteristics of description and the best accuracy, in order to be over the bidimensional GIS mapping system. DTMs, orthoimages and their 3D models overlay are performed by softwares dedicated to digital photogrammetry (ER Mapper, Surfer) and CAD designs (3dStudio Max, AutoCAD 2000). Successively these representations have been elaborated within the GIS system for a series of different themes and queries, which can be of a great support for a decision system. The use of geographic computerised system is fundamental to acquire, manage and revise all sort of information. This work shows how to create a complete, as far as the cartography is concerned, threedimensional database within the GIS system. Digital sensor derived images, or digitalised images, remote sensing acquired, or any other spatial referred qualitative or quantitative data can be used as data for the application of new methodologies and new procedures for the cartographical elaborations and their representations. Their final products, or the intermediate ones, are easily managed by very well and worldwide known systems, such as the GIS one.
