Title	Kempsey LGA (Western Portion) Vegetation. VIS_ID 244
Alternative title(s)	kempsey_west_veg
Abstract	Vegetation Distribution Map for the western portion of Kempsey Shire Council. Project undertaken by GHD consultants in 2007. The western portion is generally considered to be those lands within the shire boundary on the western side of the Pacific Highway.; ; The vegetation mapping was carried out using Landsat 5 TM (imagery taken between Dec 2004 and August 2005) scene and topographic variables as a basis for multi-variate statistical classification techniques. The image was 'seeded' with areas of known vegetation type 'samples', as determined by the field survey, from which spectral and topographic similarity was used to predict the presence of those types elsewhere in the image. A few iterations of model and map refinement and validation were then used to produce a final map that was then converted to the preferred GIS format for display.; ; VIS_ID 244

Purpose	The vegetation mapping, and associated report, aims to provide a clear, concise and practical tool for the;use of KSC. The objectives of the mapping exercise are to:;� Describe the distribution of native vegetation across the western portion of the Shire;;� Illustrate the spatial distribution of vegetation communities;;� Highlight the potential presence of Endangered Ecological Communities (EEC's);;� Highlight potential habitat corridors for Koalas; and;� Provide a suitable data set for making important planning decisions to accommodate the Shires;predicted population growth.

Lineage	2.2.1 GIS Data Reviewed; Extensive data review was carried out to gain an initial understanding of the distribution of environmental; gradients throughout the site. This assessment focused predominantly on the existing vegetation mapping from the CRAFTI data set as well as topographic variables such as elevation, slope, aspect, soil type, proximity to streams and air photo cues. A complete list of the information reviewed is included in the reference section of this report. CRAFTI is the acronym for Comprehensive Regional Assessment Forest Type Inventory and is the Aerial Photograph Interpretation Project of the Comprehensive Regional Assessment (CRA). The CRAFTI project primarily focused on mapping vegetation on non-Crown Lands. The vegetation classification adopted for the CRAFTI project was based on existing Forest Type and association; classification frameworks, adapted to broad-scale vegetation mapping by aerial photograph; interpretation.; ; 2.2.2 Process to Prepare Draft Map; From the above, roughly 60 field sites were nominated for detailed floristic assessment as well as assessment of EEC and Koala habitat significance. Whilst travelling from field site to field site opportunistic sightings of vegetation types were also recorded into a palm-top GPS unit. The strategy of selecting field sites that cover the full variety of environmental gradients for forest types throughout the study area and of incorporating opportunistic sightings of vegetation communities was intended to gain a reasonably comprehensive list of vegetation types for the study area. All records were then used in conjunction to seed the classification model.; The multi-variate classification was performed using Definiens software. The process first uses a'segmentation' algorithm to group adjacent pixels based on spectral likeness, the output of which are 22/13316/11971 Vegetation Mapping for Western Portion Kempsey LGA 4 Supplementary Report 'image objects' which are basically groups of pixels with similar characteristics. Next, areas of woody; vegetation were isolated and other areas were masked out of further analysis. From there the vegetation type records were used to provide examples from which the rest of the image could be classified based on both spectral and topographical likeness. The results of the classification model were reviewed and then post-classification refinements were implemented using decision rules based on topographic variables and class association. Generalisation tools were then applied to reduce speckle before the; final map was converted to the preferred vector format (Mapinfo TAB) for display.
