10月6日的Farm Sprayer GPS应用程序分析

Farm Sprayer GPS turns your iPhone or iPad into a simple coverage map for spraying, spreading, tillage and planting. Enter your boom or implement width, tap Start, and the app paints the ground you have covered as you drive, counts the acres, and shows where passes overlap. No subscription, no dealer, no monitor to buy. WORKS WITH THE GPS YOU HAVE • Uses the GPS built into your iPhone or cellular iPad. • Pair an external Bluetooth GPS receiver for better accuracy, or to use a Wi-Fi-only iPad. MAPS THAT WORK WITHOUT A SIGNAL • Download USGS aerial imagery for a 10, 30 or 60 mile radius around you ahead of time. When there is no connection the map switches to it by itself. • Choose Apple satellite, standard or USGS aerial map styles. A RECORD OF EVERY JOB • Start, pause and resume, then finish the field. Come back later to view it or keep spraying. • Record the crop, product, rate, operator, wind and temperature, plus notes, with each field. • Export KML (Google Earth), GPX, GeoJSON and CSV and share them straight from the app. FREE CLOUD BACKUP, OFF BY DEFAULT • Sign in with just your email, no password, to back up finished fields, view them in any web browser, share a read-only link, and get them back on a new phone. • Nothing is uploaded unless you turn backup on or tap Upload yourself. BUILT FOR THE CAB • Big buttons that work with gloves, a heads-up display with acres, speed and GPS accuracy, and a screen that stays awake while you record. • iPhone and iPad, portrait or landscape. USE WITH CARE Phone and tablet GPS can be off by several meters, and not every device has a GPS chip (Wi-Fi-only iPads do not). An external receiver gives the best results; see Antenna / More inside the app. Continuous GPS use shortens battery life. Coverage is calculated from the GPS track and your boom width: it is a record of where you drove, not a survey. EULA https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
