GPS Field Mapping Calculator

Calculate field area and perimeter using GPS latitude and longitude boundary points.

Enter GPS Coordinates (Lat, Lon)

How It Works

Coordinates are converted to meters using Earth radius approximation. Area is calculated using polygon geometry. Perimeter uses Haversine distance between points.

FAQ

What format should I use?

Enter one latitude, longitude pair per line in decimal degrees.

Is this as accurate as RTK?

No. This provides an estimate based on spherical Earth calculations and standard GPS precision.

Can I use data from my tractor display?

Yes. Exported boundary coordinates in decimal degrees will work.

About GPS Field Mapping

GPS field mapping allows producers to measure acreage using satellite-based coordinates. Modern equipment, drones, and mapping software provide latitude and longitude data that can be used to determine accurate field boundaries.

Understanding true field size is essential for fertilizer application, seed planning, crop insurance reporting, and yield analysis. Small acreage differences can significantly impact cost calculations across large farming operations.

While professional RTK systems provide the highest precision, GPS-based mapping tools offer reliable acreage estimates for most farm management decisions.
