Agroid Pro GPS meter
What is it?
AgroidPro measures distances, perimeters, areas and position dispersion (metric units). Measure your outdoor areas such as lands, estate or fields. Measure distances such as fences, paths or vineyards. Remember that GPS is not suitable for indoor measurements!!
Key features
Saving/Loading (local SD), Sharing (for printing, editing and sending Email/SMS), Satellite Map display (with GPS points/vertices/expected value/DRMS), metric and imperial units (m, km, feet, yards, miles, ha, acres, m2, km2, ft2, yd2, mi2), 3 types of maps (App Google Maps, Web Google Maps, OSM street maps), high resolution picture linking to survey points, miniatures of survey pictures on the map (App Google Maps), Average GPS (random error reduction), Position dispersion (GPS error analysis), Fine positioning of markers on Google/OSM maps.
Notes
Agroid relies on GPS data. To achieve the best results consider the following: GPS Receiver precision (automatic check, 10 m precision default), a clear view of the sky with no obstructions from about 5 deg. elevation and up (check the GPS signal dispersion with the Position dispersion function) and least but not last use the Average GPS and Fine Positioning functions to improve accuracy!
