Questions, answered briefly

What is Middle Sister?

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

Where exactly is Middle Sister?

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.
