Project a multiband image with ArcGIS and Spatial Analyst

Summary

Contained in this document are the steps necessary to reproject multiband images with ArcGIS 8.1.2 and Spatial Analyst; an ArcInfo license is required.

Procedure

1. Use ArcCatalog to convert the images to a grid.
   
   A. Right-click on the raster layer and select Export > Raster to Different Format.
   
   B. Select ESRI Grid from the 'Save as type' drop-down list. A grid will be created for each band in the imagery.
   
   
2. Use the Project Wizard (coverages, grids) in ArcToolbox to reproject each grid.
3. Add each grid to ArcMap.
4. Open the Raster Calculator and use the following syntax:
   
   

   Code:
   MAKESTACK <outgrid> <grid1> <grid2> <grid3>

   
   
   

   Note:
   Do not include a comma between input grids. Also, the MAKESTACK syntax for the Raster Calculator has changed slightly from version-to-version.  Please see the Related Information for more information.

   
   
5. Use ArcCatalog to find the new ESRI grid stack.
   
   A. Right-click the grid stack and select Export > Raster to Different Format.
   B. Select a format.
   C. Export the file.
