Overview
EN ISO 19142:2010 - Geographic information - Web Feature Service (WFS) specifies the behaviour of a Web Feature Service that provides access to and transactions on geographic features independent of the underlying data store. Published as an ISO standard (approved by CEN), ISO 19142 defines service operations, request/response encodings and conformance rules for interoperable, transactional access to spatial vector data over the web.
Key topics and technical requirements
- Service operations: Defines discovery and metadata operations (e.g., GetCapabilities), schema descriptions (DescribeFeatureType) and feature access/query operations (ad hoc and stored queries). The standard also covers property/value retrieval operations such as GetPropertyValue.
- Transactions and locking: Specifies transaction operations to insert, update and delete features and locking mechanisms to manage concurrent modifications.
- Stored/parameterized queries: Operations to create, manage and execute stored parameterized query expressions for repeatable, efficient queries.
- Encodings and bindings: XML-based encodings and alternative encodings such as Key-Value Pair (KVP) are covered, including namespace usage and schemaLocation conventions.
- Common elements: Resource identifiers, property references (XPath subsets), predicate expression encoding, exception reporting and version negotiation are standardized to ensure consistent client/server behaviour.
- Request/response parameters: Formalizes standard input, presentation and resolve parameters and standard response parameters to support interoperability and predictable service behaviour.
- Conformance and extensibility: Includes rules for conformance testing and extension points so implementers can add capabilities without breaking interoperability.
Applications and who uses it
ISO 19142 is designed for organizations and developers that need interoperable, transactional access to spatial features:
- GIS software vendors who implement WFS endpoints in desktop or server products
- Spatial data infrastructures (SDI) and public authorities exposing cadastral, transport or environmental features
- Web and application developers building map services, feature editing clients or feature catalogs
- Data custodians and integrators ensuring consistent access to distributed vector datasets for analysis, editing and automated workflows
Practical use cases include publishing vector feature layers (roads, parcels, utilities), supporting online feature editing workflows, executing repeatable analytical queries via stored queries, and enabling multi-vendor interoperability across GIS clients.
Related standards
- Part of the ISO 19100 series (geographic information) and aligns with other geographic information standards for metadata, schemas and services. Implementers typically use ISO 19142 alongside other ISO/TC 211 standards to build interoperable spatial data services.
