Cross-Tabulation of Areas

• (e.g., calculating the area of the intersection of 2 raster layers)
• Use TabulateArea ArcScript (See Install TabulateArea Arcscript)
• Create new Map Project.
• Add only the two raster layers you want to cross tabulate.
• Select TabulateArea button (it is located wherever you put it when you install the TabulateArea Arcscript).
• Fill in fields in dialog box.
• Select OK.
• The Output table will be saved to the temp folder:
• Usually something like c:\temp or c:\Dosuments and Settings\[Your Account Login Name]\Local Settings\Temp
• Or use search for a file called "tabarea*.dbf"
• NOTE: The two layers must by integer rasters
• NOTE: The first layer (Zone Dataset) will be the rows.
• NOTE: The second layer (Value Raster) will be the columns.
• NOTE: The area calculation will be in the Layer Framset units.
