Brief description
## **Abstract**The dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.
The dataset includes two shapefiles consisting of point and polygon locations of selected dams in the Sydney Basin Bioregion. The data were used to show the locations of these dams in maps. Polygon data were used to create points, as described in the History field, that could be shown and labelled in maps for context.
## **Purpose**
For display on report map images
## **Dataset History**
Selected Dam wall (line) features were taken from the 1:250k topographic data Infrastucture theme (see lineage) and converted to a line midpoint (ArcGIS feature conversion polyline to point). Two of the dams needed to be displayed were not found in the 1:250k topographic data. Medway Dam location spatial co-ordinates were sourced from the 2010 Gazetteer (see lineage). Bundanoon dam location was ascertained from Google Earth imagery. Point features for both these dams were manually edited in and appended to the 1:250k topographic data derived dam location data.
