Abstract

Native vegetation mapping of Dry Lake, Gunbar, Hay, Moggumbil, One Tree and Oxley 1: 100 000 map sheets. Native vegetation, including forest, woodland and grass/forbland assemblages, is described and mapped. Spatial delineation of map units is accomplished using stereoscopic air photo interpretation assisted by satellite imagery. Floristic composition of map units is based on analysed, plot-based floristic data collected at 748 plots (20 by 20 metres) using a random stratified sampling procedure. (VIS_ID 2215)

Lineage

Native vegetation information was collected in textual format as survey site data during a botanical survey. Trained botanists visited a series of survey sites (quadrats) and collected plant species data. The location of these quadrats was based on random sampling of Environmental Stratification Units (ESU) generated through stratifying the study area using existing digital spatial layers. Once the survey was completed then botanical records were evaluated using PATN analysis to generate floristic groups.

Simultaneously, spatial information was captured through the interpretation of 1:50 000 scale colour aerial photography supplemented by geo-rectified Landsat TM false colour satellite imagery. The aerial photography was dated 12/12/96 and 24/12/97 and the date of the imagery was 27/04/00.

Pairs of aerial photographs were viewed in stereo using a stereoscope. This process revealed a series of patterns which reflected soil, landform and vegetation types. Satellite imagery was viewed to aid in pattern identification.

In general, patterns were delineated as polygons for the stereo overlap area of each air photo. Polygons were drawn onto individual transparent acetate overlays. The minimum polygon size was 25ha. However, when possible, communities of significance less than 25ha were delineated.

In general, linework from each overlay was then transferred to 1:50 000 transparent mylars, which were referenced to a geo-rectified satellite image to minimise distortion. The final line work was captured digitally through scanning each mylar and was edited and built as a polygon coverage using Genamap GIS software.

Nine attributes were captured for each polygon and a digital spatial layer was generated (Native Vegetation (Multi Attribute) - Hay 7828). The accuracy of these attributes was checked with limited fieldwork and corrected if necessary. These attributes were then merged with floristic group data to assist with the assignment of a final vegetation community code, which became a tenth attribute.
