In ArcIMS Java viewers, the ratio of the overview map extent to the main map extent is known as the zoom factor. If the main map extent is changed by zooming-in or zooming-out, the extent of the overview map will also be changed dynamically to maintain the zoom factor. For example, a zoom factor of four means that the extent of the overview map will change when the map's main scale is less than one-fourth the overview map scale. By increasing the zoom factor, the overview map extent will not change as often for relatively small changes in the scale of the main map.

See the ArcXML Programmer's Reference Guide for more detailed information on the OVERVIEWMAP element.
