Bounding box-based catalog search of topography datasets hosted by OpenTopography
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.
For more supported operations please follow the sample requests shown on https://github.com/Esri/geoportal-server/wiki/Catalog-Service and geoportal server as a Broker help document for the different service protocols supported using the base URL
Access NASA ICESat-2 data products including global geolocated photon data (ATL03), Land Ice Height data (ATL06), Sea Ice Height data (ATL07), Land and Vegetation Height data (ATL08), Sea Ice Freeboard data (ATL10), Ocean Surface Height data (ATL12) and Inland Water Surface Height data (ATL13) via OpenAltimetry.org.
OpenAltimetry's REST API is documented using the OpenAPI specification and available via Swagger for visualizing and testing via the browser at https://openaltimetry.org/data/swagger-ui/
The Elevation Point Query Service returns the elevation in international feet or meters for a specific latitude/longitude (NAD 1983) point from the USGS 3DEP 1/3 arc-second layer hosted at the NGTOC.
The Global Multi-Resolution Topography (GMRT) Synthesis is a multi-resolution Digital Elevation Model (DEM) maintained in three projections and managed with a scalable global architecture that offers infrastructure for accessing the DEM as grids, images, points and profiles.
More information on the GMRT web service is available at https://www.gmrt.org/services/index.php
