The Graphic/Numeric Maps allows users to displays various global maps of Mars in the Viewing Window. These maps usually serve as the basis of the Viewing Window, with other layers (such as the ROI Layer, Groundtrack Layer, etc) displaying on top of them. The Graphic/Numeric Map Layer is a simplified version of the Advanced Map Layer with interfaces that long-time users will recognize. Experienced JMARS users can find information on the Advanced Map Layer wiki page.

[edit] Open a Graphic/Numeric Map

  1. Open the Map: Chose "Add New Layer" and then either "Maps by Instrument" or "Maps by Type"
  • Both sections contain the same maps, but they are sorted differently so the user can more easily find the map they are looking for.
  1. Open the Map Focus Panel: In the Layer Manager, click on the tab of the map you would like to edit.
  • If you have selected a graphical map, so data will display in the plotting section of the focus panel. If you have selected a numeric map, see below for instructions on plotting values in the focus panel.
  1. Adjust the Grayscale of the Selected Map: In the focus panel, click on the "Input" tab. On the "Input" screen, click the "+" button at the top right and select "Grayscale" from the pulldown menu. You can now edit the minimum/maximum values of the grayscale.
  2. Change the Color of the Selected Map: In the focus panel, click on the "Input" tab. On the "Input" screen, click the "+" button at the top right and select "Color Stretcher" from the pulldown menu. To change the color spectrum, right-click on the sliders at either the left- or right-hand sides of the color spectrum. Select "Set Tab Color" and choose a new color for that end of the spectrum.
  3. Using the "Configure" button: Clicking on the "Configure" button will open up the settings window associated with the Advanced Map Layer and give users full control over all map settings. For more information, visit the Advanced Map Layer page.


[edit] Plotting Values for Numeric Maps

If users open a numeric map, they are able to plot values from that map in the focus panel.
  1. Draw a Profile Line: In the Viewing Window, left-click and drag to draw a profile line. The data along that line will be graphed in the focus panel's graphing window.
  2. Retrieving Specific Data Points: To read the exact values of the graph at a given point, move the cursor to the desired point. The x-axis value is the position along the profile line and the y-axis value is the value obtained from the selected numeric map at that position. The y-axis value is displayed to the right of the numeric map's name in the focus panel.
  3. Zooming in the Graphing Window: Left-clicking and dragging in the focus panel's graphing window will create a box. When users release the left-click button the graphing window will zoom in on the selected area.
  4. Changing Input Parameters" Clicking on the "Input" tab at the bottom of the focus panel will open the input parameters for the given numeric map.
  • In the "Source" section, the names of all the loaded numeric maps are displayed. Users can change the colorization scheme of each map by using the drop-down menu on the right-hand side.
  • In the "Grayscale" Section, users can change the minimum and maximum values of the grayscale coloring scheme or set to automatic by clicking on the "Auto" checkbox.
  1. Using the "Configure" button: Clicking on the "Configure" button will open up the settings window associated with the Advanced Map Layer and give users full control over all map settings. For more information, visit the Advanced Map Layer page.
