OpenTopography for Developers

OpenTopography API

OpenTopography's REST API is documented using the OpenAPI specification and available via Swagger for visualizing and testing via the browser.

Catalogue Service for the Web

CSW (Catalogue Service for the Web) is an OGC (Open Geospatial Consortium) specification that defines common interfaces to discover, browse, and query metadata about data and services. OpenTopography provides access to its data catalog via the CSW standard. Any client supporting the CSW standard can integrate the OpenTopography CSW endpoint.

OpenTopography CSW OpenTopography's CSW endpoints are implemented using the open source Esri Geoportal Server with support for the OGC CS-W 2.0.2 standard. It supports REST, GeoRSS, OpenSearch, CSW, ATOM, GeoJSON, KML, and HTML to expose content from the catalog service to external clients.

GetCapabilities The GetCapabilities operation provides CSW clients with service metadata about the CSW service as an XML document.

Example: HTTP GET:

GetRecordById Example:{5D08C4EB-45FA-4FCB-A07A-E1B5E8B61AB3}

For more supported operations please follow the sample requests shown on and geoportal server as a Broker help document for the different service protocols supported using the base URL
