Public comment requested: OGC API - Environment Data Retrieval v1.1
The Open Geospatial Consortium (OGC) seeks public comment on the candidate Version 1.1 of the OGC API - Environmental Data Retrieval (EDR) Standard.
The OGC API - EDR Standard provides a family 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. An API compliant with the OGC API - EDR Standard will return only the data needed by the user or client, reducing data transfer time and costs.
The OGC API - EDR Standard makes it easier to efficiently access a wide range of geospatial ‘big data’ through a uniform, well-defined, simple Web interface that shields the user from the complexities of data storage. An example use case of the Standard could be to retrieve, say, weather forecasts for a local area from a much larger national or global forecast dataset – though many other types of data can be accessed through the API.
By defining a small set of query patterns (and no requirement to implement all of them), OGC API - EDR helps to simplify the design and performance-tuning of systems, making it easier to build robust, scalable infrastructures.
Version 1.1 of the OGC API - EDR Standard brings the following improvements:
- The optional use of HTTP POST as well as the HTTP GET verb. This will allow longer queries, such as when specifying a complicated, detailed area with very many points. The query payload is also encrypted and therefore more secure.
- Custom dimensions are allowed. As well as the usual 4 dimensions of space and time, (x,y,z,t), other dimensions could be offered by a data collection, such as frequency. The dimensions could also be categorical: that is, not necessarily continuous like space and time. For example, a list of wave or frequency bands, or any enumerated type. A meteorological example would be to allow data retrieval from individual ensemble members.
