Tomago sand beds

## **Abstract** \n\nThis dataset was supplied to the Bioregional Assessment Programme by a third party and is presented here as originally supplied. Metadata was not provided and has been compiled by the Bioregional Assessment Programme based on the known details at the time of acquisition.\n\n\n\nThis dataset was created from work done in a PhD thesis. \n\nA shapefile representing the Tomago sand beds digitised from an existing map which is included in the data set. The Tomago Sandbeds represent a groundwater resource, managed by Hunter Water, contributing to the lower Hunter’s drinking water supply. The sandbeds are parallel to the coast between Newcastle and Port Stephens, starting at Tomago and extending north-east for 25 kilometres to Lemon Tree Passage.\n\n## **Dataset History** \n\nA shapefile representing the Tomago sand beds digitised from an existing map which is included in the data set: tomago_sandbeds1.tif. The image was sourced from a PhD Thesis - citation below. A polygon shapefile was created in ArcGIS by georeferencing the image digitising the boundary of the sand beds shown in the map.\n\n\n\nImage source:\n\nCrosbie, R. S. (2003).
