The Aboriginal Sites Decision Support Tool ASDST extends the Aboriginal Heritage Information Management System (AHIMS) by illustrating the potential distribution of site features recorded in AHIMS.\r\nASDST was first developed in 2012 by the Office of Environment and Heritage (OEH) to support landscape planning of Aboriginal Heritage. The Tool produces a suite of raster GIS modelled outputs and is held in Esri GRID format. The first suite was published in 2016 as Version 7 at 100m resolution and in Lamberts Conic Conformal Projection (LCC). The current Version 7.5 was produced by the now Department of Planning, Industry and Environment (DPIE) in 2020 at 50m resolution in Geographic Coordinate System (GCS). Each layer covers the extent of NSW. \r\n\r\nThe suite of layers includes separate predictive layers for different Aboriginal site feature types. The feature codes used in layer naming conventions are:\r\n\r\n* ALL = model for all feature types combined \r\n* AFT = predicted likelihood for stone artefacts \r\n* ART = predicted likelihood for rock art \r\n* BUR = predicted likelihood of burials \r\n* ETM = predicted likelihood of western mounds and shell \r\n* GDG = predicted likelihood of grinding grooves \r\n* HTH = predicted likelihood of hearths \r\n* SHL = predicted likelihood of coastal middens \r\n* STQ = predicted likelihood of stone quarries and \r\n* TRE = predicted likelihood of scarred trees. \r\n\r\nThe feature models have been derived in two forms:\r\n\r\n* The first form (“p1750XXX” where XXX denotes three letter feature code) predicts likelihood of feature distribution prior to European colonisation of NSW. \r\n\r\n* The second form (“curr_XXX” where XXX denotes three letter feature code) predicts feature likelihood in the current landscape. \r\n\r\nFor both sets of feature likelihood layers, cell values range from 0 – 1000, where 0 indicates low likelihood and 1000 is high likelihood. \r\n\r\nPlease note the scale is likelihood and NOT probability. Likelihood is defined as a relative measure .
