Trajectory Query Resources of OGC API - EDRΒΆ

A trajectory is a path of a moving point described by a one parameter set of points. An illustration, created using NASA WorldWind, is shown below.

The trajectory query resource returns data for the defined trajectory. The resource offers a convenience mechanism for querying the API by trajectory, using a Well Known Text (WKT) LINESTRING geometry, or alternatively the specializations LINESTRINGZ, LINESTRINGM, LINESTRINGZM.

The path to the resource is shown below:

/collections/{collectionId}/trajectory

The paths accepts the following parameters:

  • coords

  • z

  • parameter-name

  • datetime

  • crs

  • f

An example request is shown below.
