Licence boundaries are those from the Energy Resources Act Register. Licence boundaries are legally defined to follow lines of latitude and longitude, based on potentially several geodetic datums. Processing steps; coordinates are entered by keyboard from licence documents. Line work cleaned to remove duplicate arcs. Data adjusted for accurate state border and coastline. Where appropriate cadastral parcels removed from licence polygons. Associated attribute data also captured from licence documents. Positional accuracy; most boundary locations are constructed from lines of latitude and longitude, hence are scale independent. The accuracy of other boundaries are is dependent upon the source, e.g. state border, coastline, cadastre. Attribute accuracy; validation checks are performed periodically, resulting in an estimated 90% accuracy. Logical consistency; the dataset contains no overshoots, undershoots or duplicate lines. All polygons representing licences contain only one label. Completeness; spatial data is 100% complete. Associated attribute data is 100% complete.
