See updated layer Trig Beacons now with common names in addition to survey mark codes.

Trig points with 2 metre or 4 metre beacons on the top of prominent features. They have a survey mark name and the height is the orthographic height compatible with the topo elevations, not the datum height reported by your GPS.

These points supplement the spot height in the topographic database. Spot heights are not duplicated at trig points to remove redundancy.
