Topo50 description
Only those significant by their size or location are held in the data and shown on the printed maps. Of these, tank _poly is used when the area is large enough to be captured at 1:50,000 as an area feature. Smaller features are captured as a point. Tanks in the CBD are not held in the data or shown on the printed maps.
