The data set IDs for the MOLA EGDR Data Products are: This basemap is a single Mars texture raster data layer based on a Celestia community dataset. The MOLA data greatly improved our knowledge about Mars morphology and became an extensively used reference for Mars. The relatively well-preserved ancient crust of Mars provides a natural window into early planetary evolution not available on Earth due to sustained tectonic recycling and erosion on this planet. Note: color scales differ between (a) and (b) for ease of visibility. The region of a near-planar surface that strongly contributes to the coherent echo is limited to the Fresnel zone radius: (1) r F = R λ 2 so the Fresnel zone area is proportional to R.

Until accurate topographic data became available with the use of the Mars Orbiter Laser Altimeter (MOLA), the topographic geometry of the Chasma and its distal deposit regions had been poorly understood. ) a total of over 900 DTMs have been created by multiple different institutions and released to the Planetary Data System by the Lunar and Planetary Laboratory. Our analysis of changes in valley shape with latitude and wall slope with depth indicate infilling and mass wasting processes have not greatly altered the original valley shape; thus valley Using MOLA data through October of 2000, the Science Team has produced a very high resolution topographic shaded relief map of Mars that can be downloaded for general use. The topographic surface upon which the acceleration vectors are evaluated is provided by an equal-area re-projection of the MOLA (Mars Orbiter Laser Altimeter) topography data (Zuber et al. Each HiRISE DTM covers the area of 1987] and MOLA data, we excluded all shots close to the unit boundaries. MOLA's job was to take data on the topography or surface characteristics of Mars - which it has done very succesfully.
