Description: The wilderness value is essentially a measure of remoteness from human influence and is assessed on the basis of: remoteness from settlement (settled land or points of permanent occupation), from access (constructed vehicle access routes), and apparent naturalness (remoteness from permanent manmade structures) (Lesslie and Maslen, 1995). The analysis is carried out on a grid, using data from the Digital Chart of the World (DCW), and remoteness is measured as a distance from each grid point to the nearest feature of each class within a given radius (generally 30 km). Wilderness value is the sum of standardised values for each indicator class. To provide an indication of likely quality of environment in different areas based on the formula of distance from geographic features together with associated weightings defined within the programs. GIS analysis by R. Lesslie (ANU) , method developed for the Australian Heritage Commission.
