Katalog is a free add-on to ENVI that helps organizing satellite images.

Katalog has only been tested on Windows (XP and 7). Most of its features will not work at all in other operating systems.

Installation instructions:

1. Uncompress the "katalog.zip" file.
2. Move the file "katalog.sav" and the directory "\katalog" with all its files to the "\save_add" folder of your ENVI installation. 
3. Make sure you have permission to write in this new "\save_add\katalog\" directory.
4. If you are using ENVI version 5, move the file "katalog_envi5extension.sav" to your "\extensions" folder.

It is also recommended that you download and install Google Picasa from http://picasa.google.com  
Picasa is the perfect complement to Katalog to manage all the thumbnails and it extends its search and discovery capabilities considerably.
