Abstract
Here we present the wall maps of the Moon and Phobos, which demonstrate topography of the celestial bodies. Maps of the Moon are widely used for solving important scientific tasks (Rodionova, 2000). The Hypsometric Map of the Moon is created on base of LOLA data (Smith, et al., 2010) at a scale 1:13 000 000. This map shows near and far sides of the Moon in the Lambert equal area projection. Relief is shown by contours with the combination of the hypsometric scale and shading relief (Grishakina and Lazarev, 2013). The medium level of the lunar surface is 1737.4 km and serves as zero level for heights. The height’s range on the Moon is 19.8 km. The Hypsometric Map of the Moon shows topography on the most accurate measurement to date in a global scale. Another view of the Moon’s topography is based on results of photogrammetry processing of LRO camera images (Robinson, et al., 2010): digital terrain model (DTM) GLD 100 and orthomosaic produced from LRO WAC (Scholten, et al., 2012). The layout contains two maps with relief parameters: roughness and hill-shaded relief. Both of them are created in orthographic projection with centre in 35°N and 280°E to show the eastern margin between near and far sides and the difference in its roughness. Moreover, these parameters of projection allows us to show on the both maps the most significant structures of the Lunar surface (impact basin Mare Orientale, montes of the near side and the North Pole region). Roughness of the Lunar surface is calculated as interquartile range of Laplasian (Kokhanov et al., 2013). Maps in the layout are created at the scale 1:7 000 000 and supplemented with illustrations. The map of the Martian moon - Phobos is created on the base of the newest Mars Express data: DTM and orthomosaic, produced from SRC-channel stereo images (Zubarev et al., 2012; Karachevtseva et al., 2014). The map is composed of 5 parts: one for the centre belt between 60°N and 60°S in modified Bugaevsky conformal cylindrical projection for 3-axial ellipsoid and four parts for the half-polar regions in equidistant azimuthal projection for 3-axial ellipsoid. Named features and description for the names are given in two languages (Russian and Latin). The map is supplemented by examples of 3D-modelling, which colour scheme is designed to be similar to the Phobos colour images (Neukum, 2010). Using the newest data and modern GIS technology we performed the Moon and Phobos maps using specially created digital products. Each map was designed in its special way for the best presentation of the mapped aspects: topography and roughness for the Moon or irregular shape and features of Phobos. Named features are given based on Planetary nomenclature supported by IAU (planetarynames.wr.usgs.gov). Information in the maps is presented in clear and comprehensible form that makes them interesting not only for professionals but also for all those interested in astronomy.
