Modern planetary cartography integrates the different scientific and technologic tasks: to establish the coordinate system and provide basic maps derived from image processing; to study planetary surface using GIS-tools. Here we present new maps as results of implementation of developed workflow (Karachevtseva et al., 2016a).

The geomorphological studies of the Phobos have been carried out using Mars Express images. Several sets of the grooves cross each other and form a large network. The GIS analysis of grooves has led us to the new groove catalog. Measurements of identified grooves length, width and orientation of can contribute to the understanding of their nature (Lorenz et al., 2016). Based on results of analysis a new geomorphological map of Phobos grooves has been compiled. To present the result of this study we suggested new symbols, based on groove classifications. The map represents the spatial distributions of detected grooves based on its morphological types and orientation. Identified morphological regions are shown and its characteristics are briefly described.

Studying Lunar landing sites we focused on the Lunokhods-1,-2 traverses (Karachevtseva et al., 2013; Karachevtseva et al., 2016b) using results of stereo processing (Zubarev, et al., 2016). We reconstructed the rover’s traverses, which gave us new insights into Soviet mission achievements. To present the results of study the maps of activity regions of the Soviet Lunokhods were compiled. On the hypsometric map of the Lunokhod-1 several craters were named after Russian male names and approved by IAU (http://astrogeology.usgs.gov/news/nomenclature/new-names-approved-for-twelve-small-lunar-craters); for craters at Lunokhod-2 studied area we suggested Russian female names and used them on the map unofficially for the present.
For the future Lunar potential landing sites the hypsometric map was compiled. It includes map of the Moon polar areas and inset maps of slopes near several potential landing sites suggested by Space Research Institute of Russian Academy of Science (Mitrofanov et al., 2016). With hypsographic curves and histograms the differences in the relief between the lunar northern and southern polar regions are shown: the height range in the Lunar southern region is almost twice bigger that on the north.

The new map of Mercury represents the surface using the newest global DEM (665 m/pixel) obtained from MESSENGER images (Becker et al., 2016). Elevations referenced to the sphere with radius 2439.7 km are shown by contours and hypsometric scale. The map demonstrates large forms of relief, and the inset maps show areas of morphometric studies of small features recently discovered on Mercury – flat-floored craters and hollows based on specially created DEMs with resolution up to 50 m/pixel (Zharkova et al., 2016). Names of the features are given according to the planetary nomenclature of the IAU and translated into Russian (Pugacheva et al., 2016).

Online maps created using ArcGIS online tools provide quick search and data access, for example, detailed geo-morphologic map (http://bit.ly/Ganymed_local_morphologmap2) based on new local DEM (Zubarev et al., 2015). A map legend developed to show the detailed characteristic of Ganymede’s landforms will be used for mapping of other outer satellites and for their comparative-planetological analysis.

In frame of International Map Year to update a series of maps of terrestrial planets (Shingareva et al., 2005) we have created planetary maps based on the result of image processing of data obtained by different missions. Cartographic methods can help study surface processes and address key science objectives of future planetary missions: European mission Bepi-Colombo to Mercury, Russian missions to the Moon (Luna-25) and to Phobos (Boomerang).
