Australian Geology Travel Maps by Trilobite Solutions is a simple and effective mobile app that operates offline. In addition to terrain and satellite maps, it offers a selection of interactive maps of Australia and NZ for a flat rate of $11.99 per year. These include detailed and simple geological maps by state. This is a wonderful way to locate your position on the geological map and to instantly display geological information about your immediate location. The app also has a voice function that informs you about the geology whenever there is a change, which is great for road trips.
Mineral, exploration and mining data layers can also be downloaded, and various layers can be overlaid. Locations and trails can be recorded and exported in various GPS formats.
As the internet in the Flinders can be patchy and weak, it is advised that all maps and layers be downloaded in advance. The simple geological map for SA was around 1gb and the detailed geological map for SA was around 1.4gb.
This app could very well be an improvement on using a magnifying glass to read a geological map flapping in the wind on a hot car bonnet.
