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 file
NAC_DTM_ALDROVANDI_E256N0291.IMG
 Input 6 character BIGMAP name
TEST07
 Input ltd, elng (deg)

 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

.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.
