Collections are made of multiple sensor feeds with same metadata - same number of datastreams, same metadata of said datastreams, and same licence and terms and conditions data is exposed. The sensors within the collection can have various geographical positioning.

Collection from Met Office Datapoint Forecast for next 3h accross UK

Public environment

Description:
Collection of Subset of Met Office Datapoint UK forecast for the next five days. Forecast time step available is every three-hours, updated hourly, for all of the sites as forecasted by the Met Office UK Monitoring System. That means that the value is valid for 3h from its timestamp. Observations can be found in the counterpart observation feed (please search the catalogue).

Documentation : Collections API Overview

The Developers' API is REST-based and can be accessed by issuing HTTP GET requests. All usage is measured in volume of the data returned, including where access is free. You will need to construct a URL appropriate to the dataset you're interested in and the particular information you want to retrieve.

Collections are designed to contain sensors feeds with SAME datastreams and DIFFERENT geographical location. To acquire the location list for all feeds in the collection, you should look at the top level of the feed (path 1 in the table below) and compare the feed ids with the results from our hypercat catalogue (see more at http://search.bt-hypercat.co.uk or read about it in Using Hypercat section).

Collections Snapshot can be accessed following these URL patterns for GET requests:
Path Returns
1 /collections/{collections ID} Returns metadata about the collection and list of members (feed ids).
2 /collections/{collections ID}/snapshot Returns snapshot of values in collection that are close in time.
3 /collections/{collections ID}/datastreams/{datastream ID}/snapshot For selected datastream, returns snapshot of values in collection that are close in time

To read the rest, please look at the Developers' API.


Documentation : Sensor Feeds API Overview

The Developers' API is REST-based and can be accessed by issuing HTTP GET requests. All usage is measured in volume of the data returned, including where access is free. You will need to construct a URL appropriate to the dataset you're interested in and the particular information you want to retrieve.

Sensor type feeds can be access following these URL patterns for GET requests:
Path Returns
1 /sensors/feeds/{feed ID} Metadata about the feed and streams, with current values if available.
2 /sensors/feeds/{feed ID}/datastreams/{datastream ID} Metadata about the stream, with the latest value and timestamp if available.
3 /sensors/feeds/{feed ID}/datastreams/{datastream ID}/datapoints The most recent data points or events from the past 24 hours, up to 50 as available.
/sensors/feeds/{feed ID}/datastreams/{datastream ID}/datapoints?{refinement parameters} Data points, selected according to the refinement parameters.

To read the rest, please look at the Developers' API.
