shape_coverage is used to show how many maplets are on the shape model.
It produces a text file called COVERAGE.TXT that indicates where a particular shape model is covered by maplets meeting specific criteria. The fourth column in COVERAGE.TXT is an "albedo" that correlates with the number of maplets covering that location. COVERAGE.TXTshape_coverage is often used as an input into shape2mapsA. view_shapeA can then be used to visualize the coverage on the shape.
Shape_coverage will read the files DNS_LIST.TXT, LMRKLISTR.TXT, and DNS_IGNORE.TXT if they exist. Maplet coverage will only be shown on the shape only if a maplet is present in the list being used. In order of precedence, it goes DNS_LIST.TXT, LMRKLISTR.TXT, LMRKLIST.TXT. If DNS_IGNORE.TXT exists, shape_coverage will not show the locations of any maplets on that list, regardless of whether they meet the other criteria or appear in LMRKLIST.TXT, DNS_LIST.TXT, or LMRKLISTR.TXT.
1. Run shape_coverage.
Provide the full path to the shape model and the search parameters: smin smax tol minpic
shape_coverage SHAPEFILES/SHAPE.TXT 0 .010 .1 0
- smin is the minimum maplet scale in km you wish to include
- smax is the maximum maplet scale in km you wish to include
tol is a search range along surface normal (i.e., how far to search for a maplet; same idea as densify). Units are in km.
- minpic in the minimum number of pictures. If set to 0, then all maplets will be considered.
2. Use COVERAGE.TXT as an input to shape2mapsA
