Mapio.

Mapio opens georeferenced PDF maps (GeoPDF and Geospatial PDF) and shows your live GPS position on top of them. The map lives on your phone: it works with no signal and no data. Built for fieldwork: scouting, spraying, soil sampling, construction, forestry, mining or hiking. WHAT YOU CAN DO • Import any georeferenced PDF and see it with your live location. • Measure distances, areas and perimeters in hectares, metres, acres or feet. • Draw polygons and pivots: full circles or slices, from 1% up. • Save your shapes. They stay on the map and you can edit them point by point, duplicate them and delete them. • Tap a shape in the list and the map flies to it. • Drop pins with data and photos: take them with the camera or pick from the gallery to document a weed, a gully or the crop's condition. • Use the compass, and the online satellite map when you have signal, with the same tools. • Everything keeps working offline once the PDF is imported. MAPIO PRO • No ads. • Export polygons to KML, KMZ and Shapefile, circular ones included. You choose which. • Import polygons from KML, KMZ, SHP and ZIP. • Productivity management zones: Mapio analyses up to 5 years of Sentinel-2 imagery on your own phone and splits the field into zones. • The number of zones is decided by the algorithm using the FPI and NCE indices. If the field is uniform it tells you, instead of splitting it for no reason. • The headland is kept as a separate class, so machinery traffic is not mistaken for poor soil. • Temporal stability view: which parts of the field always yield and which depend on the year. • Variable-rate prescription: several products per operation (seeding rate, starter, urea, UAN…), each with its unit and its rate per zone, plus the total to buy. The shapefile exports one column per product, ready for the controller. • Your GPS position on the zones map: you know which zone you are standing in. • You choose how much the boundaries between zones are smoothed, and see what it costs the map's quality on your own field. • An "i" button explains the full method, the sources and the limitations. YOUR DATA Your PDFs, your shapes and your photos stay on your phone. Mapio does not upload your maps to any server. Management zones use public Copernicus Sentinel-2 imagery (ESA). Contains modified Copernicus Sentinel data.
