1. Identify the type of location-referenced information that you would
like to publish or access
2. Identify the related OGC API Standard at ogcapi.ogc.org
3. Familiarize yourself with the requirements documented in the
relevant OGC API Standard
4. Use the OpenAPI definition document of the OGC API to help build
your implementation
5. Test your implementation for compliance to the relevant OGC API

‘Why’ OGC API Standards?
APIs are a very effective and popular enabler of rapid software development
API variations without standardized elements can degrade interoperability
Open Standards improve interoperability between independent implementations
OGC API Standards enhance geospatial interoperability between Web APIs

OGC API Development Principles
Spatially enable Web APIs in a consistent way
• Spatial Data on the Web Best Practices
• Leverages OpenAPI
• Focus on developer experience and usability
• Modular building blocks for access to spatial data that can be used in data
APIs
• Open development; Public GitHub, Early implementations,
In-depth validation

• OGC API Standards are becoming a key requirement for Web APIs
offering location-referenced information
• Early impact has already been seen across government, private and
academic sectors
• Organizations should start planning now to spatially enable their Web
APIs through OGC API Standards
