Web Feature Service (WFS)

OKMaps implements WFS 1.0.0 and 1.1.0 using GeoServer 2.1.x.

WFS is ideal for OKMaps users that wish to symbolize, query, and spatially analyze remote data rather than merely view the data.

The Open Geospatial Consortium (OGC) Web Feature Service Interface Standard (WFS) allows platform-independent querying and retrieval of geographic features across the Web. Unlike WMS, which returns a rendered, uneditable image for display purposes, WFS retrieves Geography Markup Language (GML) encoded features that can be edited and spatially analyzed.

Each of the topics below presents an overview of different client-side WFS requests. For more information on WFS in general, see the Web Features Service (WFS) Implementation Specifications and the Geography Markup Language (GML) Encoding Standard.

Several commercial and open source GIS and mapping software have client-side support for WFS. Examples of harnessing these capabilities with common GIS software are also provided below.
