|Medium-scale Topographic Database (GIS dataset)|
The Medium-scale Topographic Database (TGDB) provides a whole of state view of the natural and man-made features. Typically features found on the 1:25000 to 1:100000 topographic maps include Relief, Transport, Hydrography and Cultural – man made features. It is a 2D dataset with height attribution on contour and spot elevation features. Over 13 million spatial topographic features are stored in the database. Important features of the database include persistent identifiers (a unique number that is preserved during the feature’s edit life), feature level metadata and the ability to provide incremental updates.
