Public Overridable Property MinimumScale As Double

Field Value

Normally, if a Layer.Visible is trueTruetruetrue (True in Visual Basic) and the Layer is contained by the map, ArcGIS Explorer will draw it. However, as you zoom out, it may become difficult to see the more detailed information, or as you zoom in, information may become too coarse. While you can turn off a Layer, this may be inconvenient, especially if your map contains several layers or if you change the scale frequently as you work.

Layers can be set to automatically display only within an appropriate visible scale range. You can set a layers visible scale range using the Layer.MinumumScale and Layer.MaximumScale properties. The ability to set the scale range for a Layer's visibility is useful because you can progressively display more detailed layers as you zoom in on an area.

The minimum scale represents the upper bound of the scale range e.g. if the scale range between 1:100 and 1:15,000 the minimum scale is 15,000. This may seem unusual, but the terms maximum and minimum relate to the scale expressions as fractions: 1/15000 is smaller than 1/100, therefore 1/15000 is the minimum scale. If you zoom out beyond this scale, the Layer will not be visible even if the Layer.Visible property is trueTruetruetrue (True in Visual Basic).
