Implementation benefits Filter Encoding (FE) describes XML and KVP encodings for expressing filters for spatial queries to select a subset of features based on specific attributes. FE is used in conjunction with other standards and thus allows a client to, for example, create a map using a WMS that only shows residential areas.
Products FE is implemented in conjunction with other services, such as WMS or WFS. An open source examples of an implementation of FE is OpenGeo Suite 4.1.1.
