**WFS - Web Feature Specification**

Define um padrão de interface para recuperar features geographic [http://www.opengeospatial.org/ogc/glossary/g] across the Web using platform-independent calls. The WFS standard defines interfaces and operations for data access and manipulation on a set of geographic features, including: • Get or Query features based on spatial and non-spatial constraints • Create a new feature instance • Get a description of the properties of features • Delete a feature instance • Update a feature instance • Lock a feature instance

The specified feature encoding for input and output is the Geography Markup Language (GML) [http://www.opengeospatial.org/standards/gml] although other encodings may be used.
