Adding a Catalog

You can add a catalog to your Express Server from an existing folder on your web server.

NOTE: To add catalogs you must have read permissions to all Express Server folders and subdirectories and all catalogs, and write permissions to <Express Server installation directory>/ImageServer/var and its subfolders, as well as both read and write access to the source files and catalog folders. For more information see Permission Requirements.

NOTE: If you receive an error Location is not a readable Directory, Share, or Server when you attempt to create an image catalog, see Issues Creating Image Catalogs.

If you intend to use your catalog as a WMS layer, make sure it is spatially indexed after you add it. By default, Express Server attempts to spatially index all newly created catalogs by examining its first three images; if these have the same EPSG code, Express Server indexes that catalog using that EPSG code. If the first three images have different EPSG codes then Express Server does not automatically spatially index the catalog. You may force Express Server to index the catalog by specifying an EPSG code for it (see Specifying an EPSG Code). (Note: You should only do this if you have made sure that all images in the folder have the same EPSG code, otherwise your images may not line up correctly when they are viewed.)

To add a catalog from an existing folder on your server:

1. Open the Express Server Manager (see Accessing the Express Server Manager).
2. Click Catalogs on the top navigation bar.
3. Click the Create a catalog from an existing folder icon on the toolbar. The Select Catalog Folder dialog appears.
4. Navigate to the desired folder and click Add.
5. Select Basic on the left-hand navigation, then click Edit.
6. Name the catalog and set its other basic properties (see Setting a Catalog's Basic Properties).

Adding remote images

You can also add a catalog from a folder of images on a network share.

If you intend to do this, you will need to grant Read access to the remote folder to the account that runs the LizardTech Express Server Tomcat service or daemon and, on Windows, to the account that runs the IIS Web Server service. You may also need to grant access to other accounts on your Windows system.

To avoid situations where your Express Server has issues creating or accessing content in remote catalogs, we recommend that you change the default accounts used to run the LizardTech Express Server Tomcat Service and the LTESAppPool to a Domain User account that you have control over. See Specifying a Domain User Account for Windows for details.
