OGC Survey
Methodology
The Google Web API was used to extract the results of two queries in computer-readable form:
- Pages including the string request=getcapabilities, which is the common entry point for OGC web services.
- Pages including the string request=capabilities, which is the entry point for the old Web Map Server 1.0 standard.
Each returned page was pulled and searched using a number of Perl "regular expressions" for a complete capabilities URL. The Capabilities URL was in turn pulled and passed through an XML parser. The final results were stored in a database of services, servers, layers, versions, and other information extracted from the Capabilities files.
The automated process now runs monthly and populates a fresh database of information. The database was last refreshed on: 2006/10/09
Download the server list in XML form from: xml.php.
