How to measure areas and distances, save and share them, and get centimeter accuracy with an external GNSS receiver.

Practical guides

Measure field area with GPS: acres and hectaresCalculate field area and acreage with Dipper on iPhone, iPad or Android. Use a map or GPS, choose units and export a PDF. Measure fence length and perimeterEstimate fencing on iPhone, iPad or Android, follow each turn, separate gates from fence runs, and check the outer perimeter. Subtract ponds and buildings from land areaFind usable land area by subtracting ponds, buildings or other internal areas in Dipper, then check the area breakdown.

Measuring

Calculate land area on a satellite mapUse Dipper to calculate land area and perimeter on iPhone, iPad or Android. Mark the boundary on satellite imagery, edit it and save the result. Measure a distance or routeMeasure the length of a fence line, path or route in the Dipper app, with the length and bearing of every leg. GPS area measurement: walk or mark cornersMeasure land area with GPS on iPhone, iPad or Android. Walk the boundary or mark its corners; record routes and line points for distance. How accurate is GPS land measurement?Understand phone GPS, map placement and RTK accuracy, what the app’s ± estimate means, and how to compare measurements on a known plot. Field photosTake or attach site photos in the Dipper app; each is stamped with its location and direction so it appears on the map and in the PDF report.

Saving and sharing

Save and organize measurementsSave measurements with notes, colors and tags in the Dipper app, keep them in collections, and restore anything deleted within 30 days. Export and shareShare a measurement from the Dipper app as a PDF report, or export it as KML, GeoJSON, GPX or DXF for other mapping, GIS and CAD tools.

Receivers and RTK

RTK land measurement: receiver and correctionsUse an external RTK GNSS receiver with Dipper for land measurement. Learn what corrections and connections you need and how to check the fix. Choosing a GNSS receiverWhat to check before buying a GNSS or RTK receiver to use with the Dipper app on iPhone, iPad or Android: connection type, NMEA output, corrections and multi-band RTK. Connect a GNSS / RTK receiver to iPhone or AndroidConnect a GNSS / RTK receiver to Dipper on iPhone, iPad or Android using Bluetooth LE or Wi-Fi (TCP). Check positioning and satellite signals. NTRIP client for iPhone and Android: RTK setupDipper includes an NTRIP client for iPhone, iPad and Android. Add your caster details and send RTK corrections to a connected GNSS receiver. Why isn't RTK fixing?A checklist for when an RTK receiver stays at "Not yet fixed (RTK float)" in the Dipper app: sky view, corrections, base station distance, mountpoint and time. Fix levels and accuracyWhat the fix levels and ± accuracy in the Dipper app mean with an external GNSS receiver, how heights are recorded, and why correction services can disagree. Reading the sky plotHow to read the sky plot and satellite signal bars in the Dipper app, and what they say about whether an RTK receiver can hold a fix.
