This program will remove Reseaus from Viking, Voyager, and Mariner images. The Reseaus are removed using either bilinear interpolation of the surrounding pixels or by simply putting NULLs in the portion of the image around the Reseau location of the input image. The ACTION parameter is used to tell the program which of these two actions to take. The user should input the size of the box around the Reseau that will be modified. SDIM and LDIM are the sample and line dimensions of the box around the reseau. RESVALID is used to determine whether the program will check the reseau valid flag for nominal reseaux before removing the reseau. If RESVALID is NO, the program will not check the reseau valid flag for nominal reseaux and all the reseaux will be removed except invalid nominal positions. If RESVALID is YES, the program will check the reseau valid flag that is output from the findrx program. If the flag is 0, the program will not remove that reseau. If the flag is 1, the reseau will be removed. If the flag is -1, indicating an invalid nominal position, the reseau will not be removed in any case. The output cube file can be written over the input file or a new output cube can be created. To overwrite the input file, the TO parameter should be set to blank, " ". The "findrx" program, which writes the Reseau locations, Reseau type, and a valid flag to the cube file label, must be run before "remrx".

This example shows the remrx application with the BILINEAR action option. The SDIM and LDIM default to 9, and RESVALID defaults to false.

This example shows the remrx application with the NULL action option, using the same input image as the above example. The SDIM and LDIM default to 9, and RESVALID defaults to false.
