Description
This executable generates coverage for a limited area (bigmap) of what has been tiled and processed. In other words, map_coverage produces a coverage_m.pgm file that shows areas on a bigmap that have been tiled at user specified resolutions. In the image black means the area is not covered by a maplet while covered areas are bright. The brighter the area, the more maplets overlap that area.
Near the end of processing there may be thousands of maplets. To speed things up, the routine will read in LMRKLISTO.TXT if it exists. This file speeds up map_coverage by directly telling the program which maplets to show rather than searching.
Input - files
- big map, name provided in stdin
