Radial/Crater Profile lines 

This section provides instructions for displaying elevations radiating outward from a central point. This tool is ideal for creating radial profiles of circular areas, such as craters, volcanoes, sections of dune fields, or landing zones. Note: Only numeric maps can generate these profiles.

  1. Open JMARS

  2. Zoom in to a crater or area of interest (AOI).

  3. Click the 3 perpendicular dots on the blue "Layers" label in the Layer manager. Choose "Crater Counting". (To exit tool choose the arrow tool.)

  4. A new layer is added to your layers manager. Click on the Crater Counting layer to see/adjust settings. 

  5. Move your curser to the center of your crater and Zoom in (scroll on mouse) until the back circle radius is on your crater rim. It is helpful to hold the shift key as you scroll to zoom in smaller increments.  Click and then right click and select "Select mode". 

  6. Double click on "Crater Counting" layer in the layer manager. A "Crater Counting Options window opens. Click the row showing your circle data . (turns gray). At the bottom of the window, click "Open Profile Viewer". The profiles are draw from the center out (RADIALS). To chart from edge to edge (DIAMETERS) change the line type drop down menu choice. Other custom options are there also. See Options and video tutorial below for more options. For example to clear the circle shading, click on "Display", and uncheck "fill craters).

  7. To add a new circle, right click in the main window, choose crater mode, add mode. To select a drawn circle, use the curser tool, click inside the circle.
