- update and verification of topographic vector datasets, digital terrain models, orthoimages and thematic (landcover) datasets from remotely sensed data with an emphasis on mapping in a production environment.
- links between high resolution images and mapping tools developed through research, and their implementation in mapping agencies and commercial organisations.
- methods of creating and maintaining spatial databases (including 3D city models and BIMs) from terrestrial and mobile data acquisition systems.
- synergy between various sensors, for topographic and thematic mapping.
- optimum methodologies for the integration of mapping data with heterogeneous data sources.
- semi-automated and automated algorithms for updating, change detection and quality control of spatial databases as well as facilitation of the integration of these algorithms into digital photogrammetric and GIS workstations, enterprise and web-based photogrammetric systems.
- Evaluation of the information content and accuracy of new high-resolution sensors.
