State Electorate Boundaries – Modified Version of Geoscape Administrative Boundaries

Abstract State Electoral Boundaries is a digital representation of Australia’s electoral divisions or electorates. This dataset provides an optimised aggregated national view of electoral boundary geometry and attribution. The dataset is created from multiple sources including jurisdictional data which is revised regularly and supplied in varying formats and at different levels of quality. The version of State Electoral Boundaries in Digital Atlas of Australia has been modified from the original to simplify display and focus on an approximation of the latest available dataset. A rule has been applied to the map layers to: Remove any layer with the State Electoral name “LEGISLATIVE COUNCIL”, Remove layers with an EFF_End date that is NOT <Null>, Only keep the active current polygon with a <Null> EFF_END data.
