Sharing data
Mapping – TouchGIS
Touch GIS is a data collection and visualisation tool that is used to create maps to use on country or to view data collected on country. Touch GIS can be used to draw and edit points, lines, and polygons, and functions both online and offline, by caching maps before going to places without WiFi or mobile reception.
The completion of this module will be accredited as a micro-credential through Charles Darwin University, as part of the Healthy Country Digital Monitoring collection.
