Format of Overlay Files

When creating an overlay, you must transfer the points from a map to an overlay file.

There are 2 major paths available to you when building an overlay file: absolute or relative coordinates.

Overlay files are defined with a special syntax. A small set of simple statements specify the location of the radar and place the text or lines on the map. A semicolon (;) marks the beginning of a comment line.

The END statement marks the end of the map. Anything that appears in the file beyond the END statement is ignored.

tip It is sometimes helpful during editing to put an END in the middle of a file, so that Overlay plots only the map lines and text up to that point.
