This is a program R. Gaskell wrote to ingest a PDS IMG DTM into a bigmap. Was written specifically for LRO products such as the type found here.
- Requires a MAPFILES directory one level down from the directory with the IMG DTM
Example of terminal with input and output
<rand> aldrovandiStart$ ~/X-files/source/PDS2BIG.e InputIMG file NAC_DTM_ALDROVANDI_E256N0291.IMG Input 6 character BIGMAP name TEST07 Input ltd, elng (deg) 26.160 29.075 scale, qsz, R0 .01 650 1737.4 3222 11963 12888 1737.40 6064.67 24.58 26.55 28.81 29.40
From above, showing only the input values
NAC_DTM_ALDROVANDI_E256N0291.IMG TEST07 26.160 29.075 .01 650 1737.4 # GSD of final bigmap in kilometers, Q of final bigmap, body radius (Bob used Lunar Datum, not sure how much you can deviate from this)
If you are getting this error...
Note: The following floating-point exceptions are signalling: IEEE_INVALID_FLAG
check lat and lon to make sure at least some of the IMG pixels are present in the locations you've specified.
