A preliminary global DTM reconstructed by a method combining the stereo and clinometry information

A preliminary global DTM reconstructed by a method combining the stereo and clinometry information (e.g., MSPCD) with a horizontal sampling of 1 m in PLY format.

Mapping of gas sources back onto the shape model

Mapping of gas sources back onto the shape model in a to be defined format

A set of local DTMs

A set of local DTMs covering the surface of C-G imaged by OSIRIS at a resolution comparable to that of the images in a format recognized by the ArcGIS and QGIS software (the GeoTiff format is foreseen).

A set of 3D files (SHAP7 shape model with OSIRIS image texture)

A set of single 3D files (binary PLY format with an accompanying JPG texture file) for 3D display and analysis; each 3D file contains the 500K facet version of the SPG SHAP7 model, textured with one OSIRIS image. The set of files will consist of 3D files for almost all OSIRIS NAC F22 images and OSIRIS WAC F18 images showing 67P's surface.

A global DTM reconstructed by a method combinging the stereo and clinometry information (final)

A global DTM reconstructed by a method combinging the stereo and clinometry information (e.g., MSPCD) with a horizontal sampling of 1 m in PLY format. This should be final, but it may be necessary to update at M30.

Maps of albedo, acceleration, gravity field and grav. Slopes

Maps of the following parameters: albedo at 625 nm, acceleration, gravity field and ratio of the gravity over centrifugal acceleration (calculated using the algorithm of Werner and Scheeres 1996), gravitational slopes.
