Instructions provided describe how to change border colors for pseudocolor raster catalogs in ArcGIS. ArcGIS 9.x and 10 raster catalogs have the ability to change renderers used for display. This document explains how to change colors for pseudocolor; or colormapped, rasters in a raster catalog. This is useful for removing the borders of USGS DRG catalogs and making them appear seamless.
Due to a known issue, ArcGIS 9.x and 10 pGDB Raster Catalog's unique value renderer behaves differently depending on whether the rasters in the catalog use .IMG or another file format. If the raster catalog being used for the procedure below is a pGDB, it must either be a managed raster catalog or an unmanaged raster catalog that references the .IMG files.
This may take some time. Do not click 'Stop'.
The colors displayed are the default red color ramp. Ignore them. They are not used.
To use this renderer again, save it to a layer file. Otherwise, the default Colormap renderer is used the next time the catalog is loaded.
