Brief abstract or additional comments (maximum 100 words)

The NSW Geology phone map is designed primarily for use on Android and Apple phones, but also runs on tablets. The map itself is downloaded and stored on the user’s phone or tablet so that no mobile reception is required in the field. This is important, as for most of rural NSW, mobile reception is either poor or non-existent. The user can centre the map at their current location, allowing them to determine the geology under their feet – or of nearby features. Roads, towns, rivers, national parks, state forests and topographic relief all provide a context for the geology. In addition to this, facts about the 106 major rock units are displayed. When a user touches the phone screen, a simple pop-up reveals the rock unit name and age, and then detailed information is shown if the simple pop-up itself is touched. Scale-dependent styling (using CartoCSS) is designed to display an increasing amount of information as the user zooms in, avoiding clutter at the broader scales.
