Got WMS?


I discovered a great resource last night as I was looking for a catalog of Web Mapping Services (WMS) to consume while standing up an Open Source GeoServer Stack.  Back in 1994 the Open Geospatial Consortium (OGC) established a number of standards for geospatial data formats and services.  The Web Map Service has become essential for the exchange of geospatial data through the web.  Worldwide there exist thousands of WMS services offering data with hematic content.

Mapmatters.org is a service that catalogs and tests WMS feeds.

Mapmatters has cataloged more than 1000 WMS services.  Through text or geographical extent searches users can find layers of interest.  Each layer can be previewed on a map or with pre-compiled thumbnails.
In addition to the catalogue mapmatters  also assesses performance and reliability of  WMS services.  For many layers information is available, for instance, how long it takes to download maps from the service and how many times a request failed.

Mapmatters is both a tool for the end-user to find a WMS service that fits the needs of a specific application with respect to the thematic contents and the required technical quality and a tool that tracks how well the service performs and to quickly be notified in case of failure.

Mapmatters is currently in a beta stage and will be extended continously.  Mapmatters.org is a project by GeOps
