Application | ISO 19143 describes XML and Key-Value Pairs (KVP) encodings of a system-neutral syntax for expressing projections, selections and sorting clauses, collectively called a query expression. |
Conformance classes | Query Ad-hoc Query Functions Resource Identification Minimum Standard Filter Standard Filter Minimum Spatial Filter Spatial Filter Minimum Temporal Filter Temporal Filter Version navigation Sorting Extended Operators Minimum XPath Schema Element Function |
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. |
