GPS Land Area Calculator

Measure the area of any field, farm, plot or garden by walking its boundary with GPS, or by typing the corner coordinates from your land record. Plotline is a GPS land area calculator that gives the answer in acres, hectares, square feet and local units such as bigha, guntha, katha, kanal and marla. No ads. No subscription.

WHY PEOPLE SWITCH TO PLOTLINE
• Walk the boundary: press Start walking, go around the field and press Finish. Plotline skips vague readings and GPS jumps, keeps recording with the screen off and works offline, with no internet connection.
• Accurate maths: area and perimeter are measured on the WGS84 ellipsoid with the geodesic method used by surveying software. No size limit, from a garden to a whole farm.
• Honest local units: a bigha in West Bengal is not a bigha in Rajasthan, so every local unit shows its region. If your records use another size, add your own unit.
• Acres included, with hectares, square metres, square feet, square yards (gaj) and more than 30 local units.
• Easy from the first minute: a short 3-step guide shows how it works, and every screen tells you what to do next.
• Precise corners: on the plot sheet, tap to add a corner, drag a stake to move it (a magnifier shows the exact spot), delete it in one touch, undo and redo any change.
• Calm: no ads at all, no pop-ups, no "rate us" nagging and no account.

TWO WAYS TO MEASURE
1. GPS walk: walk around the field with your phone ("Trace my path"), or use "Stake corners" for straight-sided plots: stand on each corner for a few seconds and Plotline averages the GPS readings.
2. Enter coordinates: decimal degrees (18.5204, 73.8567) or degrees, minutes and seconds (18°31'13"N 73°51'24"E). Paste a whole list at once.
Then check and adjust the shape on the plot sheet, a scaled grid with every side length.

RESULTS YOU CAN USE
• Area in your main unit plus the units you pick, perimeter, every side length and the corner coordinates.
• A warning when the boundary crosses itself, with one-tap untangle.
• Save fields with a name, notes and the date (5 fields in the free version).
• Share the figures as text on WhatsApp, SMS or email, free.
• Pro: export KML for Google Earth and GIS apps, and a PDF field report with a scaled plan, every measurement and the corner table.

LOCAL UNITS INCLUDED
Guntha, cent, decimal (dismil), ground, ankanam, kanal and marla (India and Pakistan); bigha, biswa, katha, dhur and lessa for Punjab, Himachal Pradesh, Uttarakhand, Uttar Pradesh, Rajasthan, Bihar, Jharkhand, West Bengal, Assam, Gujarat, Madhya Pradesh and Bangladesh; and Nepal's bigha, kattha, dhur, ropani, aana and paisa. Lengths in metres, feet, yards, miles, chains and links.

A FIELD AREA MEASURE APP FOR REAL WORK
Farmers checking a plot before sowing or buying, landowners comparing a field with the land record, surveyors and contractors who need a quick land measurement, gardeners and sports clubs. Plotline gives the answer in the unit you think in.

PRIVATE BY DESIGN
No account, no sign-up, no ads and no analytics. Your fields stay on your phone. Location is used only while you walk a boundary, and Plotline never uploads it.

PLOTLINE PRO: ONE-TIME PURCHASE, NO SUBSCRIPTION
Unlimited saved fields, plus KML and PDF export. Pay once and keep it. Measuring, GPS walk, all units and text sharing stay free.

Good to know: phone GPS is usually accurate to a few metres under open sky. For the best result, wait for good GPS before you start and walk at a steady pace. Plotline is a measuring tool, not a legal survey.
