This page contains statistics for the layers, and services that are searchable via GeoSeer.
To the best of our knowledge GeoSeer has the largest index of such data, and while it is representative of the global state of OGC services, it's not a complete survey.

Caveat: The numbers below represent the number of layers after clean-up and post-processing (i.e. duplicate removing). The actual number of public layers GeoSeer's index represents is anything from 50-100% higher than the number given below. See this blog post for more information about counting layers.

Glossary

Hosts
- These are unique (sub)domains. For example, all of these count as one Host (www.example.com):
  • www.example.com/orange_county/wms
  • www.example.com/roads/wfs
  • www.example.com:8090/grids/ogc
But ogc.example.com would be considered a different host.
Endpoints
- These are the public URLs that Services are available via.
All of these are different Endpoints:
  • example.com/orange_county/
  • example.com/roads/
  • example.com/geoserver/roads/
It is important to note that we remove any Service specific (i.e. WMS/WFS/etc) components for Endpoints.
All of the following only count as one Endpoint (example.com/orange_county/):
  • example.com/orange_county/wms/
  • example.com/orange_county/wfs/
  • example.com/orange_county/ogc/
Services
- A Service is a URL that is serving one of WMS, WFS, WCS or WMTS. Services are basically Endpoints with the service-specific parts left in.
These are all different Services:
  • example.com/orange_county/wms
  • example.com/orange_county/wfs
  • example.com/roads/wms
Layers
- An individual data layer within a Service. Meaningless layers are not counted, nor are duplicate layers that are the same across an Endpoint.
See this blog post for more information about counting layers.
These are all different Layers:
  • example.com/layers/wms - Roads
  • example.com/layers/wms - Trees
  • example.com/layers/wfs - Roads
  • example.com/services/ogc - Roads
Distinct Layers
- If a layer is accessible from the same endpoint but via different services, we count that as a single distinct layer.
See this blog post for more information about counting layers.
These are all one Distinct Layer (Roads):
  • example.com/layers/wms - Roads (via WMS)
  • example.com/layers/wfs - Roads (via WFS)
  • example.com/layers/wmts - Roads (via WMTS)
