     These standards are being constructed as "building blocks" that can be used to assemble novel APIs for web access to geospatial content. The building blocks are defined not only by the requirements of the specific standards, but also through interoperability prototyping and testing in OGC's Innovation Program.

 #### More OGC APIs
 
 The OGC API effort is rapidly evolving. Numerous OGC API standards are in development, and will be implemented in
 pygeoapi over time:
 
-- [Maps](https://ogcapi.ogc.org/maps) can serve spatially referenced and dynamically rendered map imagery
 - [Routes](https://ogcapi.ogc.org/routes) provides access to routing data
 - [Styles](https://ogcapi.ogc.org/styles) defines a Web API that enables map servers, clients as well as visual style editors, to manage and fetch styles
 - [3D GeoVolumes](https://ogcapi.ogc.org/geovolumes) facilitates efficient discovery of and access to 3D content in multiple formats based on a space-centric perspective

 In the next section we will dive into the dedicated API's related to specific types of information. You will
 notice that all APIs are combined and available via a single OGC API endpoint, thanks to OGC API - Common.
