Convert camera image to a different camera image

This program will convert a input camera cube to a different camera geometry. For example, given overlapping MGS MOC and Odyssey Themis cubes, this program can convert the MOC image to have the same geometric camera characteristics as the Themis cube (or vice versa). Another use is to align bands in a camera cube which has independent bands. For example, a raw Themis cube (after thm2isis) will not have aligned pixels. This program can be used to align the pixels without going to a map projection. To prevent pixels from falling off the edge of the cube you can run pad on the cube prior to this program.

Jesse Mapel2018-05-17 Changed transform to use the local radius computed by the output camera instead of having the input camera re-compute it (sometimes incorrectly) from the latitude and longitude. Fixes #5425.

Parameters

Files

The camera cube which will be modified
Type cube
File Mode input
Filter *.cub

This is the camera cube which will be matched. It must be only one band so use the input attributes to select the band to match. For example, themis.cub+5.
Type cube
File Mode input
Filter *.cub

The resultant cube which will have the same camera geometry and image size as the match cube.
Type cube
File Mode output
Filter *.cub

Options

This is the reference band to be used in the MATCH cube. That is, all bands in the FROM cube will be matched to this band. The default is to use the middle band; however, the user can enter any band number which is valid for the instrument, regardless of whether the band is in the cube or not. This only applies to band dependent camera models such as Themis.
Type integer
Internal Default middle
Minimum 1 (inclusive)

This is the type of interpolation to be performed on the input.
Type string
Default CUBICCONVOLUTION
Option List:
Option Brief Description
NEARESTNEIGHBORNearest Neighbor Each output pixel will be set to the pixel nearest the calculated input pixel.
BILINEARBi-Linear interpolation Each output pixel will be set to the value calculated by a bi-linear interpolation of the calculated input pixel.
CUBICCONVOLUTIONCubic Convolution interpolation Each output pixel will be set to the value calculated by a cubic convolution interpolation of the calculated input pixel.
