10月20日的Tractor GPS应用程序分析

Drive straighter passes, see exactly what you have covered, and know the real size of every field — using just your iPhone or iPad. Tractor GPS turns the device in your cab into a guidance and record-keeping tool for tractors, sprayers, seeders and harvesters. No extra hardware. No account to create. AB LINE GUIDANCE • Tap A at the start of your first pass and B at the end — the app draws parallel guide lines spaced to your implement's working width • A live readout shows how far you are off the line, with an arrow telling you which way to steer • Guidance snaps to whichever pass you are nearest, and you can nudge one pass left or right • Guide lines fit automatically to a selected field boundary COVERAGE MAPPING • Worked ground is painted behind the machine as a band the width of your implement • See at a glance what is done and what is left • Pause between passes and continue when you are ready • Clear the painted path and start a pass clean whenever you need LIVE IN THE CAB • Speed, covered area, elapsed time, distance and working width at a glance • Applied spray volume when your equipment has spraying turned on • Pick a field before you start and get a progress bar, remaining area and an estimated time to finish FIELD MEASUREMENT • Draw a boundary on the satellite map point by point, with undo • Walk or drive the perimeter and let GPS build the shape • Create a circular center-pivot field from a center point and a radius • Every field stores area, perimeter, name, description and color IMPORT AND EXPORT • Import existing boundaries from KML, KMZ, GPX, GeoJSON and Shapefile — hundreds of parcels at once • Export a field as PDF, GPX, KML, KMZ, GeoJSON or zipped Shapefile • Export a finished job as PDF, GPX, KML, GeoJSON or zipped Shapefile • Hand records to an agronomist or a co-op, load them into farm software, or keep them for paperwork EQUIPMENT PROFILES • Save each implement with its working width and left or right offset from the device • Offset correction puts the painted coverage where the implement actually runs, not where the device sits • Set a spraying rate per area or per minute and get applied volume and average rate for the job JOB RECORDS • Every finished session is saved with worked area, duration, average speed, work rate, distance and spray volume • Organize jobs into folders, add notes, and link a job to a field • Reopen a job later and keep adding to it — a field split across two days stays one record TWO SCREENS, ONE GPS • Mount your iPhone where it sees the sky and relay its position over the local network to an iPad for a bigger in-cab display • Ideal for a Wi-Fi-only iPad, which has no GPS of its own • Fields, jobs and equipment sync across your own devices through iCloud — no server, no sign-up BUILT FOR THE CAB • Normal, satellite and hybrid maps, in 2D or tilted 3D • Light and dark themes • Optional compass, keep-screen-on, and a choice of markers including an animated 3D tractor • Metric and imperial units, set independently for area, distance, speed and spray volume • Available in 41 languages Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
