Accepted Norms
The currently accepted prime meridian of Mars is centered on the crater Airy-0. From there you can measure longitude using any system, degrees/minutes/seconds, decimal degrees, east/west, positive/negative, [lon, lat], [lat, lon], whatever. The prime meridian's location is fixed, but after that all bets are off.
MOLA data uses planetocentric latitude (as opposed to planetographic latitude).[1]
There is a system of quadrangles invented by the USGS which are occasionally used, and serve as the basis of the Marspedia Mars Atlas.
The zero-altitude datum is not officially standardized, though most maps I've seen use MOLA elevation data, which is defined to be relative to a datum defined by the gravitational field of Mars.[1]
Web-based Maps
Marspedia proposes the Mars Atlas. there are a number of alternatives, however.:
- JPL "Mars Trek"
- USGS Mars Global GIS Mapping Application
- Google Mars
- Life On Mars? - Visualize "filling up" to different sea levels.
- Interactive Curiosity path through sol 351
- 3D contours by Stamen
Downloadable Maps
Data Resources
- MOLA data
- OpenPlanetaryMap datasets
- OpenPlanetaryMap basemaps
- USGS available vector layers and basemaps
- Feature names
Software Tools
