OGC adopts environmental data retrieval specification as an open standard
By Open Geospatial Consortium
The Open Geospatial Consortium (OGC) has approved the API – Environmental Data Retrieval (EDR) specification as an OGC standard. The standard eases users access to subsets of spatial big data through a uniform, well-defined, web interface that hides the complexities of data storage.
OGC APIs are modern, modular “building blocks for location” that lets anyone publish or consume geospatial data on the web in a manner that’s findable, accessible, interoperable, and reusable.
An important aspect of the EDR API is that the data can be unambiguously specified by its spatiotemporal coordinates – a “where” and a “when”. The standard provides a set of lightweight query interfaces to access spatiotemporal data resources by requesting data at a Position, within an Area, along a Trajectory, or through a Corridor.
The patterns supported by the query interfaces provide useful building blocks to allow the composition of APIs that satisfy a wide range of geospatial data use-cases, from the retrieval of real or virtual time-series observations, to sub-setting four-dimensional data cubes. By defining a small set of query patterns (and no requirement to implement all of them), the API – EDR standard helps to simplify the design of systems and makes it easier to build robust and scalable infrastructure that is performance-tuned for its supported queries. The standard can also support more general spatiotemporal data, making it useful across many domains and applications. As with any OGC standard, the API – Environmental Data Retrieval standard is free to download and implement. Learn more on the OGC API – EDR webpage.
