Positional Accuracy

Comments

There are three different data sources that are reliant on spatial position used to derive the product, however, the primary data source (satellite imagery) is an orthorectified product as supplied by DSE Victoria. This product has been found to be accurate to within one hundred metres against all other reference information available. Largest issues are seen in scenes taken at shallow angles and in steep terrain.
