Drawing concentric polygons

Image:cratercrop.png

It is not possible to draw "doughnut" polygons with the JMARS shape layer, however, the same effect may be achieved by drawing the inner (yellow in example above) and outer polygons (orange) and then arranging the display order of your polygons. To arrange the display order, left click on the row with the polygon of interest and drag it up or down.

How do I assign a value to multiple features at the same time?

In the "Features" section of the Shape Layer focus panel, users can edit a particular field for multiple rows simultaneously by:

  1. Highlight the rows you want to edit.
  2. Right-click on the column you want to edit for the selected rows.
  3. Select "Edit Column of Selected Row"
  4. Enter either a value or text in the pop-up input window and click "Ok"
  5. All of the highlighted rows will reflect the change in the selected column.
