10月26日 的 PlotZone: MGRS & UTM plotter 應用程式分析

Type it, draw it, measure it, export it. Nothing is collected, and nothing leaves your phone. Built for drone pilots, glider and free-flight pilots, search and rescue teams, surveyors and military personnel. ONE-TIME PURCHASE Bought once, yours for good. No subscription, no in-app purchase, no sign-up, no password. MISSIONS Group your points and zones by operation. Each point carries a name, its coordinates, a radius in meters, feet or nautical miles, and a color. Drag it on the map. One tap undoes it if you got it wrong. Duplicate a whole mission to build a variant without typing it again. BULL'S EYE Pick one point as the reference. PlotZone gives the bearing and distance from it to every other point, and draws rings every 10 NM out to 120 NM, with radials every 30°. The reference travels inside the exported file, so whoever receives the mission reads the same bearings you do. COORDINATES Five formats, both ways: decimal degrees, degrees-minutes-seconds, degrees-decimal-minutes, MGRS and UTM. Tap the map to read a position, tap a result to copy it. Five geodetic datums to choose from: WGS84, NAD27, ED50, OSGB36 and AGD66. Every coordinate is read and typed in the one you pick. 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 come in on a single load. Show several areas at once, set their opacity, turn each on and off with one tap. MGRS GRID Draw the MGRS grid at 1 km or 100 m, labeled the way a military map is: grid zone, 100 km square, and the principal digits of every line, read right then up. At a grid zone junction the grid switches zones with you. The GARS grid overlays the same way, at 30' or 15', with its designators. YOUR LIVE POSITION Your position is followed live, with its accuracy, in the format you chose. Tap a point, or any spot, and the top of the screen gives the bearing and distance from where you stand, updated as you walk, with a line drawn to it. TRUE OR MAGNETIC Bearings in true north, as on a map, or in magnetic north, as on a compass. The declination is the one where you stand: the device reports it, or you set it by hand. Nothing is downloaded. MEASURE Two taps, on the map or on points you have plotted, give the bearing and the distance between them, at the top of the screen. IMPORT AND EXPORT Export a mission to back it up or pass it on, and import it back with nothing lost. Eight formats: PlotZone (.json), a plain-text brief, CSV for a spreadsheet, GPX for a handheld GPS, KML and KMZ for Google Earth, GeoJSON for mapping tools, OpenAir for flight computers. BASE MAPS Three maps from Apple: satellite, hybrid and standard. Their imagery needs a connection the first time an area is shown. You can also import your own map in MBTiles: its tiles are copied to the device and drawn over Apple's, so your sector stays readable with no network at all. ACCESSIBILITY Every control is named for VoiceOver, symbols included. 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.
