Supplementary material to: Highly resolved topography and illumination at Mercury south pole from MESSENGER MDIS-NAC

We produced a new higher-resolution topographic map of Mercury’s south polar region (75°-90° South, covering ~1.3 million km²) by using data collected by the NASA MESSENGER spacecraft’s Mercury Dual Imaging System (MDIS; Hawkins et al, 2007) over the years 2011-2015. This new map enables, e.g., the first detailed modeling of illumination and thermal conditions in these southern radar-bright locations and the first constraints on the nature and history of volatiles residing there, but it is also intended as a resource for other geophysical analyses and for the preparation of the BepiColombo mission, currently en-route to the planet.

Products:

DEM (interpolated), DEM (filled), Slopes, PSR masks, elevation differences to Mercury's USGS DEMs (download GeoTiff)

Geospatial products are distributed as 32-bit raster compressed GeoTiffs in Mercury South Polar Stereographic projection (with a mean radius of 2439.4 km) and with a pixel size of 250 meters. 

Notes about this version:

• Inconsistencies in the GeoTiff metadata (planetary radius) and values have been fixed.
• A map of elevation differences to the reference USGS Mercury DEM has been included
• All products are now available as Cloud Optimized GeoTIFFs (COG)
