The derived shapefiles can be
downloaded for each separate PDS product, including data listed as follows.
The shape files including *. shp, *.shx, *.dbf, and *.prj are zipped into
*.zip or *.tar.gz format. After download, they need to be unzipped first. Then,
shape files can be loaded in ESRI ArcGIS.

Because many of the coverage maps are quite large, in addition to the coverage file encompassing the entire planet,
ODE provides a set of 45x45 degree coverage tiles. The tiles have their upper left corner in latitude/longitude included in their
file names. These tiles are generated by selecting all products with their CENTERS inside the tile.
NOTE: FOOTPRINTS THAT CROSS INTO A GIVEN TILE BUT WHOSE CENTERS ARE IN THE NEIGHBORING TILES ARE NOT INCLUDED IN THE GIVEN TILE.
Users should load the neighboring tiles when working close to a tile edge or products with large footprints.
Please review the coverage file naming convention in the ODE help.
The following folders contain ODE generated footprint coverage files grouped by mission, instrument, and product type.
