Topo50 description

Only those significant either by their size or location, or where contours do not adequately depict the terrain, are held in the data and shown on the printed maps. Note that those in heavily build-up areas are not usually held in the data or shown on the printed maps. A named cliff may be held in the data as a geographic_name feature, and shown on the printed maps by it's name only. Eg. 'Benvenue Cliffs'

Topo250 description
