AusCover, is providing an online and mobile means to test and validate maps of land-cover and biophysical variables
As it is difficult to obtain accurate validation data over large areas, the Geo-Wiki website allows “citizen-scientists” and volunteers to view, with Google Earth as a backdrop, these maps in real time, and apply their local area knowledge to determine if the classification is correct or incorrect. If the mapped features are deemed incorrect, the volunteer submits information on which land-cover class or other variable would be more appropriate. The submitted validation information is recorded and used iteratively to produce new and more accurate land-cover and other biophysical parameter maps.
