GSNSW interactive geology maps are now available to download using the ArcGIS Field Maps mobile application. ArcGIS Field Maps is the new replacement for the ArcGIS Explorer app platform provided by ESRI. Follow the quick installation steps below to download the application and maps onto your mobile device.

These interactive geology maps display a range of information. Touch the screen to reveal the name, description, age, lithology and environment of formation of the underlying rock type. Your location appears on the map, which can be re-centred to your current location with just one touch.

A useful tool for geologists, geophysicists, engineers, farmers, environmental consultants, students and anyone interested in geology, landforms and soils.
