PlotZone: MGRS & UTM plotter

You are given a position in MGRS. Your map is in decimal degrees. You need a bearing and a distance. By hand it is slow, and it goes wrong.

PlotZone does all three on one screen.


ONE-TIME PURCHASE

No subscription, no in-app purchase, no advertising. No account, no sign-up, no password. No data collected: everything stays on your device.


MISSIONS

Group your points and zones by operation. Each point carries a name, its coordinates, a radius in metres, feet or nautical miles, and a colour. Drag it on the map. One tap undoes it if you got it wrong.


BULL'S EYE

Pick one point as the reference. PlotZone then gives the bearing and distance from it to every other point, and draws rings around it every 10 NM out to 120 NM, with radials every 30°.


COORDINATES

Five formats, both ways: decimal degrees, degrees-minutes-seconds, degrees-decimal-minutes, MGRS and UTM. Touch the map to read a position, touch a result to copy it.


ZONES

Type the vertices in your usual coordinate format, or draw the polygon with your finger. Adjust each vertex, watch its area and perimeter as you go, then save the zone into a mission to keep it.


AIRSPACE

Load your working area from your own files, whether they hold a georeferenced chart or plain outlines. PlotZone reads KMZ, KML, OpenAir and GeoJSON. Outlines, markers and names all come in on a single load, with no need to open the file a second time. Show several areas at once, set their opacity, turn each on and off with one tap.


GARS GRID

Overlay the GARS grid at 30' or 15', with its designators.


MEASURE

Two taps on the map give the heading and distance between them.


IMPORT AND EXPORT

Export a mission to back it up or pass it on, then import it back with nothing lost. Four formats: PlotZone (.json), KML, KMZ and GPX.


BASE MAPS

Satellite, hybrid or plan, depending on what you are looking for.


ACCESSIBILITY

Every control is named for VoiceOver, including the buttons that show nothing but a symbol.


WHO IS IT FOR

Drone pilots, glider and free-flight pilots, search and rescue teams, surveyors, military personnel. Anyone handed a position in one format who has to work in another.


PRIVACY

PlotZone does not collect, store or transmit any personal data. Your missions are saved on your device alone. Your GPS position is used only to draw you on the map. It is never transmitted or shared. No account, no tracker, no analytics, no advertising.

Available in English, French, Spanish, German, Italian, Dutch, Portuguese and Chinese.


DISCLAIMER

Coordinate conversions and distance calculations are provided for guidance. Always check your data against an official source before any critical use. PlotZone is not a certified navigation instrument.
