Title |
Nominal Impervious Surface Map - Greater Sydney |
Abstract |
Impervious surfaces were derived from two existing mapping products, producing six classes of impervious area: Buildings, Roads, Railways, Roads and Railways, Airports and Aerodromes, Stormwater Infrastructure. Impervious Surfaces associated with buildings were derived from the Geoscape® Buildings Theme, which provides polygon representations of every building in Australia with a roof area equal to or greater than 9m2. Building polygons from the Greater Sydney Region were extracted and used to create the ‘Buildings’ feature. Impervious Surfaces not associated with buildings were derived from the NSW Land Use Map 2017 (inclusive of the draft Land Use Mapping for the Sydney Metropolitan Region), which provides land use mapping for NSW at a 1:10,000 reliability scale, based on the Australian Land Use and Management Classification Code. This layer was used to generate the Roads, Railways, Roads and Railways (polygons reclassified during QC) Airports and Aerodromes, and Stormwater Infrastructure features. Once both sets of features had been generated, they were intersected with LGA to aid in computation and provide additional map utility. Following this, any overlap between the Buildings features and the Land Use features was corrected using the Erase Function, before the layers were combined using the union function, and dissolved by LGA and feature class to provide LGA-level breakdowns of the prevalence and providence of impervious areas. |

Lineage |
This product was developed using two existing mapping products: the Geoscape® Buildings Theme and the NSW Land Use Map 2017 (including draft mapping for the Metropolitan Sydney Region). The Geoscape® Buildings theme v1.3 was developed by the PSMA using remote sensing imagery provided by digital globe, historic aerial imagery, and existing cadastre data to map all rooftops within Australia with an area greater than 9m2. This information is provided alongside supplementary information such as the address, material and colour of every roof, whether that roof includes solar panels, and whether the address includes a swimming pool. The NSW Land Use Map 2017 was developed using existing cadastre mapping, council zoning data, and multiple sources of aerial and street level photography to map land uses across NSW at a 1:10,000 reliability scale. Land Uses were determined in line with the Australian Land Use and Management (ALUM) Land Use Classification based on currently available information. |
