noproj - Compute camera distortions. NOPROJ produces a transformation file (TFILE) to GEOM to remove or restore electronic camera distortions on cubes, no other geometric corrections (such as map projections) will be made or removed. If the mission for the cube is Viking, Voyager or Mariner, FINDRX must be run on the cube before NOPROJ to find the reseau positions and store them on the cube labels. GEOM must be run after NOPROJ to actually transform the cube. PROGRAMMER: Kay Edwards U.S.G.S. Flagstaff
Parm | Description | Default |
---|---|---|
FROM | Input cube file name (Default extension is .cub) | NONE |
TFILE | Transformation file (No default file extension) | tfile.dat |
SPACE | Grid spacing (2,4,8,16,32,64) | 16 |
OPT | Create an UNDISTORTED or DISTORTED cube | UNDISTORTED |
ADDITIONAL NOTES:
Parm | Description |
---|---|
FROM | Input cube file name. If the file extension is omitted, then ".cub" will be assumed. The labels of the cube to be transformed must contain reseaus if the spacecraft name is Viking, Voyager or Mariner. |
TFILE | This is the name given to a data file needed by GEOM. After this program has finished GEOM must be run to actually transform the cube. |
SPACE | This is the spacing of a rectangular grid in pixels which is overlayed on the output cube. A distortion correction is calculated at each intersection. This parameter determines how often this calculation is done. |
OPT | This option allows the user to create either an undistorted cube (UNDISTORTED) or a distorted cube (DISTORTED). Raw and LEVEL1 cubes are distorted. |
