Images of planetary bodies usable for making topographic maps have been, and will continue to be, acquired by many planetary missions. For photogrammetric compilation, special imaging instrumentation have been developed in the last years. The Astronomical Observatory of Padova (OAPD-INAF) is involved in different missions, which are keystones for the planetary photogrammetry in particular Bepicolombo and Exomars 2016.

The BepiColombo mission has started in October 2018 its journey toward planet Mercury. On board of the spacecraft, the imaging suite SIMBIO-SYS  (Spectrometers and Imagers for MPO BepiColombo Integrated Observatory SYStem) dedicated one of its channel, the STC  STereo Camera,  to the  global stereo coverage of the entire planet surface.

The second mission, ExoMars, was launched in 2016. Until now, the CaSSIS (Colour and Stereo Surface Imaging System) stereo camera has rescued thousand high resolution stereo images of the Mars surface.

The INAF-OAPD institute, as part of the CaSSIS team, leads the Digital Terrain Models (DTMs) generation in association with other team members.

With this scope our team developed the 3DPD, a suite of stereogrammetric and imaging tools designed for processing stereo imagery captured from satellites image. It produces cartographic products, including digital elevation models (DEMs), ortho-projected imagery, 3D models. These data products are suitable for science analysis and public outreach. Here you can see some of these products.

In addition, INAF-OAPD is responsible for DTMs archiving  thanks to a Repository Dynamic Interface for the management of the DTMs reconstruction requests.
