Schema documentation for component diggs:GP

A linear sampling feature that records the geographic location of a geophysical survey that can be modeled as a single linestring - such as a ground-surface transect, marine trackline, or airborne flightline, where receivers (and optionally source devices) are placed on or moved along the track. This differs from the more general Transect sampling feature insofar as its use implies association with a GeophysicalFieldSurvey measurement as well as possibly being associated with other GP_Trackline features as part of a GP_Multitrack sampling feature. As with all linear sampling features, the geometry is specified by the centerline property using 2D or 3D coordinates within a known geographic or projected coordinate system. Allthough not required, where possible the centerline vertices should occur at specific receiver locations where measurements are obtained or at measurement locations for a receiver that is moving along the track (ordered in the direction of movement).

Database handle for the object. It is of XML type ID, so is constrained to be unique in the XML document within which it occurs. An external identifier for the object in the form of a URI may be constructed using standard XML and XPointer methods. This is done by concatenating the URI for the document, a fragment separator, and the value of the id attribute.
