GTS JSON Output Format

Geo Time Series data retrieved from the Warp 10 platform can be retrieved in a compact JSON format.

The returned value is an array of objects, each object being a chunk of Geo Time Series.

Each chunk has the following fields:

Field	Description
c	This is the class name of the Geo Time Series. This may be present in only one chunk of a given Geo Time Series in the output.
l	This is an object containing the labels of the Geo Time Series. This may be present in only one chunk of a given Geo Time Series in the output.
a	This is an object containing the attributes (key/value) of the Geo Time Series. This may be present in only one chunk of a given Geo Time Series in the output.
i	This is an id which is unique per Geo Time Series in the output (but not across outputs). All chunks of a given Geo Time Series will have the same id and can therefore easily be identified and merged.
la	If the last activity is enabled on the platform, this is timestamp of the last activity.
v	Array of Geo Time Series readings.

Each reading is itself an array containing 2, 3, 4 or 5 elements.

The first element of the array is the timestamp of the reading in microseconds since the Unix Epoch.
The last element of the array is the value of the reading, the type of this element varies with the type of the reading.
When the reading array has 3 elements, the second element is the elevation of the reading, in millimeters.
When the reading array has 4 elements, the second and third elements are the latitude and longitude of the reading.
When the reading array has 5 elements, the second and third elements are the latitude and longitude of the reading and the fourth is its elevation.
