The easy way to set the visualization scale for map layers is outlined below:

  1. From a map window, zoom in to a point at which you want a map layer to become visible.
  2. From the Map Layers dialog, right-click on that map layer to set its visualization scales. From the shortcut menu, click Set Scale for Zoom-in. This sets the visualization scale for the map layer. If you go to the map window and zoom out, the layer will no longer appear.
  3. Inversely, if you want the layer to become visible as you zoom out, from the shortcut menu, click Set Scale for Zoom-out.
  4. Visualization scale settings can be cleared or disabled. From the shortcut menu, click Remove Scale Factors. The visualization scale for the layer is cleared.
