Map a Planet: Astrogeology Cloud Processing

Map a Planet (MAP) is a cloud processing tool from the USGS Astrogeology Science Center. MAP allows users to select global or regional image mosaics through the Astropedia database. Images may then be map projected, clipped to extents, and have basic analysis run against the image bands. Users can then download the final image in their choice of file formats.

Downloaded files can then be used for geologic mapping, analysis in a Geographic Image System (GIS), change detection, merging of dissimilar instrument images, and use in a host of other scientific applications (e.g., ArcMAP, ENVI, Matlab, JMARS, etc.). Output formats currently supported include ISIS, PDS3, GeoTiff, Jpeg, and PNG.


Quick step-by-step

  1. Find an eligible product from Astropedia.

  2. On the product's page, when available, click the MAP "process" button

  3. Supply your email address and then select your MAP processing parameters (e.g. map projection, resolution and output format) and submit.

  4. We will email you when you can download your processed product.

  • ISIS - ISIS (version 3+) is an image processing software package. The focus of the software is to manipulate imagery collected by current and past NASA planetary missions sent to Mars, Jupiter, Saturn, and other solar system bodies.

  • GDAL – Geospatial Data Abstraction Library is used for conversion from ISIS (version 3) format to GeoTiff, Jpeg, and PNG. Conversion to PDS3 format is handled by ISIS.
