The 3 main objectives of the survey were to: 1) To create a vegetation map for Nitmiluk National Park to guide targeted land management. 2) To describe the patterns in vegetation types and significant species in the Park 3) To test and compare methods for generating vegetation maps. The survey analysed more than 1500 vegetation plots between 200 and 2002. Two separate analyses were undertaken, one concentrating on describing the patterns in the floristic data and the other using GIS data to derive a vegetation map. The resulting landcover map describes 13 vegetation classes; distinguishing the substrate (soil and rock) and structure of vegetation and provides mapping at three different scales, 1:50 000, 1:100 000 and 1:250 000. Nitmiluk National Park covers an area of 1,000 km2 of mostly rocky country enclosing the upper reaches of the Katherine River. The main park entrance is located approximately 30km from the townsite of Katherine.

Polygon topology rules applied are; must not overlap, must not have gaps and each polygon has only one label.0not knownEach polygon in the 3 land cover datasets contains a label with a series of attributes all based on 13 final classes. Refer to Data Dictionary described in Metadata below. The attribute BESTCLASS is the most likely, most correct class/outcome based on analysis. More detail on the floristic composition and environmental information, for each CLASS, is contained in the associated report.0Data Source: Landsat 5 TM imagery - 2 neighbouring scenes 27/04/95 and 24/03/97; 100k DEM sourced from DIPE; NT Airbore Radiometric Data sourced from NT Geological Survey (flown 1974-2002); existing geological and land system mapping (250k) were deemed too course to use. The final Land Cover Map was derived using eCognition software and mapped at three scales (50k, 100k, 250k) for Nitmiluk National Park using an object-based classification incorporating Landsat TM data, radiometric data and elevation and slope models. The communities mapped using this method are described in reference to habitat data collected from 1364 ground plots and floristic data collected from a further 1557 plots distributed throughout the park. Comparisons with historical land systems mapping is also presented.
