The proposal addresses for the aspects of enrichment, updating and visualiziations of 3D building models. It serves four principal goals 1) to integrate the cadastral information with the 3D geometries of individual buildings by means of data matching, 2) to extract and interpret non-visible features from thermal infrared data based on image analysis coupled with context information from 3D building models, 3) to update as well as enrich the 3D building models with the information derived from non-visible features, and 4) to visualize semantic attributes describing various surface elements of updated and enriched 3D building models with emphasis on time-dependent thermal information. The involved tasks will be jointly accomplished by the Department of Cartography and the Department of Photogrammetry and Remote Sensing. The data sources from a selected test urban area include: 1) polyhedral descriptions of individual buildings, 2) a number of bulding attributes embedded in city plans, cadastral maps and real estate databases, 3) thermal infrared images (...).
