The DLL plug-in build_image_catalog_dir.dll will build an Image Catalog for any type of image that ArcMap supports from a single directory. Thus it will add Grids, Bils, Tiffs, etc. into one catalog. To only add Tiffs, create a new directory and copy or move the Tiffs into that directory and then rerun. It will not overwrite an existing file. Delete old catalogs before running. The catalog name will contain the directory name with "_Catalog.dbf" added to the end. The directory must not be readonly also - so it cannot be on a CD or DVD.
*** To run you must choose the parent DIRECTORY of the images not the images themselves.
Uploaded as an VB DLL with VB project and code. Built in ArcMap/ArcCatalog 8.3 and ArcMap 9.
Installation:
Tools -> Customize, add from file. This will create a "USGS" catagory, drag "IC" icon to a toolbar. If at any point this process returns an error, it is probably because you need administrator access.
To set an Image Catalog's background to Null check out "copy & Paste Image Symbology" http://arcscripts.esri.com/details.asp?dbid=13128
History:
