| Zusammenfassung |
| Introduction: The Soviet rover missions Lunokhod-1 and -2 were launched at the beginning
of 70th (Luna-17 in October 1971 and Luna-21 in January 1973 respectively). The main
goals of the both missions were to study Moon surface in situ. The history of the Lunokhods’
missions came back into focus recently, when the Lunar Reconnaissance Orbiter obtained
high resolutions images.
Sources. For our work we used various data: LROC Narrow Angle Camera (LRO NAC)
images, 0.3-1 m/pixel [7, 11]; DEMs with different resolution: LRO NAC DEM, 1-5 m/pixel
[9]; Kaguya DEM, 7.5 m/pixel [10]; Lunokhods’ stereo panoramas and early cartography
information [1, 8].
Methodolody: We collected all data as spatial database (Geodatabase) which includes
various derived products. Based on methods developed earlier [4, 6], rovers wheel tracks and
craters entire study regions were mapped. High resolution DEMs allow calculate of
various morphometric parameters of the Lunokhods’ regions which provide better
understanding processes on lunar surface [2, 5]. Method of detailed morphology
analyses developed for study area now used for investigation of the Luna-Glob
and Luna-Resource landing missions which are planned to the south pole of the
Moon.
Data access: We are developing easy access to the planetary data based on web and
spatial technology (Geoportal). Geoportal provides the ability to view spatial data
in the web-browser, displays different layers in the same area at different scales
turns the web. Lunokhods’ data point features were created for each station of rover
routes where panoramas were been recorded. So GIS project provide an easy access
to non-spatial image database and can involve these information in their spatial
context.
Conclusions: During Lunokhods’ missions early topography data of the traverses were
accurate for most areas. Modern estimating these results based on the new LRO data provide
comparative studies in lunar geology and morphology. We show that these data can be used
for detailed mapping of landing sites for future lunar exploration missions (Luna-Globe and
Luna-Recourse). Using PDS4 standard [3] we are developing Geoportal for easy access to
the Lunokhods’ panoramas and derived products based on results of newest lunar
missions.
