The HRSC on board ESA's Mars Express will image the entire planet in full colour, 3D and with a resolution of about 10 metres. Selected areas will be imaged at 2-metre resolution.

== Data description ==

MarsSI propose the following products from the HRSC dataset:

 * RDRv3 : Radiometric Data Record, version 3, 1-channel
 * REFDRv3 : map-projected RDR products, 1-channel
 * DEM : Digital Elevation Model

These images are usually in the PDS data format, the suffix indicates the data content of the image:

 * ND = nadir
 * BL = blue
 * GR = green
 * IR = near IR
 * RE = red
 * DT = DEM sphere
 * DA = DEM aeroid

There can also be S1, S2, P1, P2 and ND types that represent panchromatic channels [TODO: find if the wavelengths are constant across images]

== Downloading HRSC data ==

=== HRSC Imagery ===

From the “Maps” tab, zoom-in on your region of interest, you can display the THEMIS mosaic for more precision, and then display the "MEX - HRSC RDRv3" layer. You get all HRSC RDRv3 footprints that appear in purple. The footprint are regularly updated to take into account new data. You can use the “Select” button to choose the footprints you desire. You can choose several footprints by clicking several stamps, or by dragging your mouse to select adjacent footprints. You can also use the “Search” button for more options. 

=== Digital Elevation Models ===
