SensorML 2.0 Examples

In order to support a wide variety of needs for providing location, orientation, and dynamic state of a physical component or system, there are several means for specifying "where". These include byDescription, byPoint, byLocation, byState, byTrajectory, and byProcess.

If the location is static (i.e. unchanging) and orientation is not relevant, one may indicate location using the GML Point.With gml:point, the order of coordinates and units of measure are specified by the Spatial Reference System (SRS) definition. Although this is sometimes confused in implementations, the order for the coordinates of the SRS 4326 should be latitude, then longitude in decimal degrees.
