The easy way to set the visualization scale for map layers is outlined below:
- From a map window, zoom in to a point at which you want a map layer to become visible.
- 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.
- Inversely, if you want the layer to become visible as you zoom out, from the shortcut menu, click Set Scale for Zoom-out.
- Visualization scale settings can be cleared or disabled. From the shortcut menu, click Remove Scale Factors. The visualization scale for the layer is cleared.
