shape_coverage

Category DART	Version 1.0

Description

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.

Input Files

SHAPEFILES/SHAPE.TXT. This could be SHAPE.TXT or some other shape model (e.g., SHAPE1.TXT, etc.)

DNS_LIST.TXT

LMRKLISTR.TXT

LMKRLIST.TXT

DNS_IGNORE.TXT

/MAPFILES

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.

Output Files

SHAPEFILES/COVERAGE.TXT

Using shape_coverage

1. Run shape_coverage .

Provide the full path to the shape model and the search parameters: smin smax tol minpic

shape_coverageSHAPEFILES/SHAPE.TXT0 .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

shape2mapsASHAPEFILES/COVERAGE.TXT

3. Use view_shapeA to visualize the coverage on the shape. Note that if you only run view_shape, you will not see the coverage.
