Project a pseudocolor raster using ArcGIS and ArcInfo

Summary

Projecting a pseudocolor raster from one coordinate system to another can be done using the following steps.

Procedure

1. Convert the raster to an ESRI Grid and a colormap file using ArcToolbox > Conversion Tools > Import to Raster > Image to Grid. Specify the name of the output grid and the name of the output colormap file.
   
   

   Note:
   The colormap file should have a .CLR extension.

   
   
2. Define a projection for the grid using ArcToolbox > Data Management Tools > Projections > Define Projection Wizard such as coverages, grids, TINs.
3. Project the grid using ArcToolbox > Data Management Tools > Projections > Project Wizard such as coverages and grids.
4. Convert the projected grid and colormap back into an image using ArcInfo Workstation GRIDIMAGE command:
   

   Code:
   Arc: GRIDIMAGE mygrdprj colormap.clr newimage.tif TIFF

   
   

   Note:
   At ArcGIS 8.x there is a known problem with the ArcToolbox Grid to Image tool that does not allow it to use a colormap file for TIFFs.
