The objective of this project was the production of a native forest cover dataset for the Northern portion of Australia classified to nationally agreed specifications.

Digital cover is available for export0not knownGood - Dataset topological consistency has been system checked and all classified polygons are closed, nodes are formed at the intersection of lines and there is only one label within each polygon. Polygons have been classified for Community ID in the lookup table0not knownGood - Derived from topographic basemap, NT cadastre and GPS. The summation of errors from all sources results in data with a standard deviation defined by scale used as +/-250m for well-defined points0not knownHigh - The accuracy of the attribute information is considered high and conforms to the 'Australian Soil and Land Survey Field Handbook' at time of capture. Analysis of site data to provide community information0Original linework/vegetation patterns delineated using satellite imagery with radiometric calibration, geometric correction and image registration classified into a maximum of 25 classes using an Isodata unsupervised classification method in ERMapper 6.0 to delineate mapping unit boundaries and site selection, then extensively ground-truthed with topographic basemap/GPS coordinated field survey and site data collection. Resultant verified linework georeferanced to GPS ground control points and 1:25,000 topographic basemap then input into GIS system as ArcInfo vector information and built as a polygon cover. Recompiled and updated to GDA94 as part of ongoing GIS Progarm 2004.
