• The development of KATGIS has priority in the current research projects. KATGIS is a strict, object-oriented, workflow-controlled application for the Smallworld GIS, based on the new data modell ALKIS7 which is used for the keeping of a cadastre. In particular, a homogenization of general Smallworld-objects (also for other applications than KATGIS), called KATHOM, which can be configurated independently, is developed in addition to tools for the analysis, keeping and data output of ALKIS7 objects.
• Development of the digital photogrammetric evalutation system PHIDIAS: PHIDIAS completely integrated into the 3D-CAD-system MicroStation and is used for many different surveying tasks in architecture, archeology, preservation of monuments, industry and criminalistics.
• Non-standard data bank systems: conception and development of persistent object-storages for OO-languages such as C++. The prototype of a persistent object-storage for C++developed here serves as centre (?) of the OODBMS, which shall be used for information management in information systems, especially for GIS.
• Semantic modelling: development and implementation of a system for the automated analysis of (hand-written) reduced-scale drawings. The system is used for the automated recognition of objects in reduced scale-drawings (such as survey points, buildings, land parcels, etc.) and for their transformation into a digital form. These objects are then processed by means of geo-information-systems (GIS).
• Statistics and adjustment computation: the adjustment program KAFKA is used and developed for the analysis and evaluation of any kind of geodetic survey, from the orthogonal survey/survey by quasi-perpendiculars (?) to GPS-surveys. KAFKA processes 18 different observation types (?) and delivers plausible coordinates with a good quality of neighbourhood
• In order to homogenize digital cadastral maps or power supply maps, the system KATHOM is developed and maintained. It produces homogeneous maps taking geometric constraints into account and can also be applied to changes of reference system. The system is able to derive with coordinates with a good quality of neighbourhood.
