Many of us have struggled to get a list of GIS services that are available on the internet. Specifically map services that expose OGC based interfaces like WMS, WFS or Web Service interfaces like REST, SOAP etc.
If you start with weather, transportation, demographics, agriculture, this list becomes huge!
These sites are not easy to use, don't have the most updated info and don't have a good taxonomy/ classification of services towards easy discovery of such services.
Is there a better attempt out there to create an exhaustive, searchable catalog of all such services? I would like to know their usage rights, free or pay etc. Uptime, performance etc. would also be nice to know.
