Mars Image Atlas

The handoff

Open an image in JMARS

JMARS is Arizona State University's free, open source GIS for Mars and other bodies. It runs on your computer and shows images in place on a globe, with ASU's layers and tools around them. This atlas finds the image. JMARS is where you work with it.

Install JMARS once

  1. Go to jmars.mars.asu.edu.
  2. Open the downloads page and pick the installer for your computer.
  3. Run the installer. JMARS needs a 64-bit computer and at least 4 GB of memory.
  4. Open JMARS and follow ASU's getting-started guide.

Then, for each image

Every image page here shows the steps below with the ID already filled in. The layer and the field depend on the camera.

  1. Open JMARS. It is free from ASU at jmars.mars.asu.edu.
  2. In the Layer Manager, click Add New Layer, then Stamps, then THEMIS Stamps.
  3. Expand Image Location Parameters with the down arrow on its right.
  4. Type the image ID in the Image ID(s) field. Use the observation ID: a letter (V for visible, I for infrared), a 5-character orbit number and a 3-digit image number, for example V98565007. After orbit 99999 the first orbit digit becomes a letter, so VA1466014 is orbit 101466.
  5. Click OK. The search can take a few minutes.
  6. Right-click the image outline in the viewing window, then choose to render the image.

Search by area instead of ID

  1. Open the same stamp layer dialog.
  2. Fill in Min/Max Longitude (0 to 360, east positive) and Min/Max Latitude.
  3. Click OK.

The search box on a results page here lists the same numbers, so you can copy them across.

Footprints as a shapefile

The Orbital Data Explorer offers each image's footprint as a zipped shapefile, linked on every image page. JMARS has a Shape Layer that reads shapefiles in longitude and latitude. That route is not tested by this site yet.

What about the Moon?

Public JMARS can switch to the Moon (Body, then Select Body, then Luna). ASU documents an LROC stamp layer only in its LROC team release, and no ShadowCam layer. So this atlas covers Mars for now. Moon search may come later, once the JMARS step is confirmed.
