The traverse map shows the rover's movement over time in context of the broader area. Use the traverse map to find data based on location.

What the map shows

Mars rover traverses are plotted on an Mars Reconnaissance Orbiter HiRISE base map. Red markers show locations where data were acquired. Sol numbers are shown beside some markers. (Autonav images that support driving and intermediate long-term data collection products are not included in establishing these locations.)

The Apollo traverses are plotted on Lunar Reconnaissance Orbiter LROC high-resolution controlled mosaics and show stations, instruments, and sample collection locations.

Moving around the map

You can move around the maps several ways.

  • Use your mouse to zoom and pan around the map.
  • Use the controls in the upper left corner.
  • Use the Go to site and Go to sol drop downs on the menu bar.
  • Drag the shaded box in the overview window. (The window can be opened and closed by clicking on the arrow in the upper right corner of the map.)

Linking to data

Click on a marker to see a snapshot of what's available at that location. For the Mars rovers, you might try using the Go to site/sol drop downs if your coordination is not so hot—you have to click pretty close to the center of the red marker. When you click on a marker, a popup will show a summary of one or more locations at that spot. You'll see the site/drive/pose, the sol(s) when the rover was there, and a synopsis of the data, documentation, etc. that's available (see image below).

Click on the summary and the results will appear in the Location panel to the left (see image below). This should look familiar—it's pretty much what you see in the sol summary listings. From here, you can access the data and such for the current location.

How the traverse map is made

mission specific

APO

The background image is clipped from the LRO LROC NAC high-resolution controlled mosaics. Images were produced using USGS ISIS by the LROC team at Arizona State University. Traverse lines are from Phil Stooke, University of Western Ontario. They was created by tracing tracks visible in the LROC data as well as using surface photos and descriptions.

msl

The base map is a subset of the Gale_C_PSP_010573_1755_010639_1755_25cm image georeferenced by Tim Parker and Fred Calef for their localization activities. The traverse is generated by applying the best_tactical places solution updates to the raw rover telemetry.

MER

The base maps are reprojected MRO HiRISE images using MOLA-controlled bundle adjustments. The traverse is produced by MER science team.
