Questions, answered briefly

What is John Britten crag?

A named cliff in Christchurch, at Heathcote Valley, as the open map records it.

Where exactly is John Britten crag?

The pin is OpenStreetMap’s own position for the cliff, the formation’s own ground, or its centreline’s middle. Neighbours on the register are near it, not the same record.

The record behind this

The position and the names are OpenStreetMap’s, a named cliff, rock, reef or quarry inside the city boundary (ODbL). The dual names and the crag names are recorded as the map carries them; a pin is the mapper’s position, not a surveyed mark.
