PDS2BIG

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 fileNAC_DTM_ALDROVANDI_E256N0291.IMG Input 6 character BIGMAP nameTEST07 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.IMGTEST0726.160 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)

Troubleshooting

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.
