This app allows you to turn your smartphone into a measuring station GNSS (GPS, GLONASS, Galileo, etc.). useful topographical environment to do a quick survey or to store our points of interest.
The App works with the Rilievi Smart (http://rilievismart.altervista.org/) portal that allows, once the relief ends, to comfortably view the points on the map and get a wealth of information.
Attention, the app's accuracy depends on the present GNSS sensor in your smartphone.
