English abstract:
The I.P.F. is Co-Investigator at ESAs HRSC on Mars Express project. Its main task is the development of an information system for HRSC data (High Resolution Stereo Camera) that should be the main interface for data exchange between the Co-Investigators of this project. Further on it can be used as a presentation web portal to act as data source for the whole mars scientists community. This can be realized easily, because the information system is designed as web application using XML (eXtensible Markup Language) related technologies.

Besides the institute uses its experience in handling large topographic data on the MOLA-2-Dataset. It uses SCOP, a software for interpolation, management, application and visualization of digital terrain data, which was implemented in cooperation of the I.P.F., Vienna and INPHO GmbH, Stuttgart.

Current results are

- a global Digital Terrain Model (DTM) of Mars (Resolution: 4500 m) which was calculated in one job
- automated error elimination of track referencing errors and computation of a high resolution DTM of Vallis Marineris (Resolution: 330 m)
- the ability to apply this automated error elimination method (based on robust estimation) on the global MOLA-2-Dataset

Furthermore derived products are computed from such DTMs. Special focus is set in hydrological analysis using rain simulation and in visualizations such as perspective views, VRML (3D) models, ... that can be visualized using any kind of raster overlay (MOC images, shadings, height codings, ...). As volcanoes are very interesting regions from a topographic point of view, lots of them are already visualized.
A new extension of SCOP allows to compute 360 panorama views of an area. So it allows to do a landing site simulation, long time before the lander has touched the surface of Mars.
