Scale Dependency

When adding a new data layer to the project the default scale dependency will be set to all,essentially meaning that the layer will be visible at all scales. If the map projection and units have been set for this project it is possible to make any of the layers scale dependent, that is, visible between certain scale bounds.

Steps For Making A Layer Scale Dependent

  1. Right-click on the layer in the legend. A new menu will popup.
  2. Click on Layer Properties. The Layer Properties dialog will be displayed.
  3. By default the Minimum and Maximum Scale settings under the Scale Dependency section will be -1, which means the layer is not scale dependent.
  4. Change the Minimum Scale to a valid scale value. This is the minimum scale at which a layer will be visible.
  5. Change the Maximum Scale to a valid scale value. This is the maximum scale at which a layer will be visible.


For example, for a layer to be visible below 1:50000 set Minimum Scale to -1 and Maximum Scale to 50000. For a layer to be visible between 1:20000 and 1:50000 set Minimum Scale to 20000 and Maximum Scale to 50000.
