{ "currentVersion": 10.91, "id": 4, "name": "Buffers_for_Building_Positional_Accuracy", "type": "Group Layer", "description": "About 5% of all buildings depicted in the web service were originally captured for purpose of generating topographic map products at small scales i.e. 1:250,000 or smaller. These features may have been generalised or offset from their true position for cartographic representation purposes. Therefore, positional uncertainty associated with these features is depicted as buffers from 1:144,000 scale or larger. The buffers indicate that actual real-world feature may be sighted anywhere within it. The remainder of buildings have much greater positional accuracy and hence smaller buffers, corresponding much closely to buildings visible on base imagery, such as that provided by Bing and Google. Refer to http://www.ga.gov.au/mapspecs/topographic/v6/section1.html#FeatureLevelMetadata; See 3.7.4 Absolute Planimetric Accuracy for a description of the formula used to capture the TOPO250K GEODATA products.
