The Queensland topographic map service is based on data acquired and collated by the Department of Natural Resources and Mines, Queensland for more than thirty years. This data is used primarily for the creation of the 1:25 000 Topographic Map Series covering various parts of Queensland. The service uses a map cache created for the following scales: 1:18,084, 1:36,112, 1:72,224, 1:144,448, 1:288,895, 1:577,791, 1:1,155,581, 1:2,311,162, 1:4,622,324 and 1:9,244,649. The map cache will be refreshed periodically to show updated data.
