Inserting a Map Grid

The Insert  Map  Grid operation creates a longitude-latitude grid (Figure 15-7) within the current dataspace, using the current projection. If no projection is active, then IDL uses geographic coordinates.

Figure 15-7: The Map Grid

The gridlines appear as a single MapGrid object within the current dataspace. For information on this visualization, see Map Grid.


Note
When you insert a map grid, the Axes container within the dataspace is automatically hidden. To display the axes, use the Visualization Browser to change the Show property of the Axes container.
