OGC WMS Support

Express Server supports version 1.1.1 of the OGC WMS specification.

WMS Feature Support

This release of Express Server supports the following WMS calls:

• GetCapabilities
• GetMap

This release of Express Server does NOT support the following features:

• GetFeatureInfo
• Style Layer Descriptors

WMS Service URLs

The base URL for accessing WMS functions from the Express Server is

http://<server>/lizardtech/iserv/ows?

Example: GetCapabilities

The following URL returns the capabilities of a WMS-enabled Express Server:

http://demo.lizardtech.com/lizardtech/iserv/ows?service=WMS&request=GetCapabilities

Caching the Capabilities Response

The Express Server dynamically generates a capabilities document in response to each GetCapabilities request, unless the file <Express Server installation directory>/ImageServer/var/wms.capabilities.xml exists. If this file exists, then it will be sent as a response to the GetCapabilities request.
