Range Ring Controls
Overview

The range rings control shows a set of concentric circles labeled by distance from the central point, with radial lines, useful for judging distance and angle from a geographic location. You display range rings from the Main Display window with the Display->Add Range Rings menu item. Range rings are often used with radar imagery. The control window is composed of two tabs: Location and Settings.

The Location tab allows you to specify the location to center the range rings:

The range rings are oriented with local north-south on the displayed map projection. In some cases, the eastward radial line may not be horizontal. The range rings will appear centered on the map projection. You can move the range rings by resetting the latitude-longitude or the station. McIDAS-V can display multiple range rings at once and at any location.
