Contour Visualizations

Using the Visualize Perspective, you can create visualizations of contour data. This example uses a variable entered at the command line to open elevation data for a mountainous area called Maroon Bells.

  1. Make sure you are viewing the IDL Visualize Perspective. (Click the Visualize button (viz_button.gif) in the upper right of the Workbench.)
  2. Enter the following at the command line (or click on the code below to run it in IDL):

    3. RESTORE, FILEPATH('marbells.dat', SUBDIR=['examples','data'])

    The ELEV variable appears in the Variables View.

  3. From the Variables View, drag the ELEV variable to the Contour tool.

    4. Note
    This example assumes the default action definitions. Your results may be different if you have added new actions or changed the order of actions. To return all Tool Palette actions to their system default state, see Resetting the Default Actions.

    The iContour window displays a basic visualization of the elevation data:
