Project a full color (RGB) or multiband image

Summary

Before you project a multiband image, you need to convert it to a grid stack, project each individual grid of the stack, add the bands to a new stack, and convert it back to an image.

Procedure

1. Convert the image to a stack:
   
   

   Code:
   Arc: IMAGEGRID img.tif img

   
   The grid stack will be called 'img' and the grid bands will be 'imgc1', 'imgc2' and 'imgc3'. If there are more than 3 bands in the multiband image, more grids will be present.
   
   
2. Project each individual grid.
   
   

   Code:
   Arc: PROJECT GRID imgc1 imgc1prj
   Arc: PROJECT GRID imgc2 imgc2prj
   Arc: PROJECT GRID imgc3 imgc3prj
   

   
   ArcInfo 8.x offers the PROJECTGRID command. All previous versions offer the PROJECT command with the GRID option.
   
   
3. Create the new grid stack.
   
   

   Code:
   Arc: GRID
   Grid: MAKESTACK imgprj LIST imgc1prj imgc2prj imgc3prj
   Grid: QUIT
   

   
   
4. Convert the stack back to an image.
   
   

   Code:
   Arc: GRIDIMAGE imgprj # imgprj.tif TIFF
