Concern about the effects of land development on Phillip Island is felt by all who view fast-tracking of planning scheme amendments as a threat to the status of heritage sites. Accordingly, some interest attaches to up-grading decision support for site-specific consensus building. Here demonstrated, is a visualization-based up-grade centred upon a very detailed DTM generated over a high resolution DEM derived using the ground return data from a LiDAR point cloud, feature extraction being completed by integration of image data with the first returns and the intensity data. With the addition of time-series land cover overlay, this model is shown to be efficacious in supporting, not only the kind of spatial query that public land managers make routinely, but also those which emerge when during attempts at land-use conflict resolution such as those which are heard by the Victorian Civil and Administrative Appeals Tribunal
