Case Study: PointPlot achieves precise, hassle-free land surveying and site marking with what3words

PointPlot Surveying App & what3words

PointPlot is an iOS surveying app from ndm.io that makes it easy to mark corners, take photos, add notes and calculate area, distance and perimeter. The challenge was giving users a simple, reliable way to capture and share accurate location data in the field—particularly when sight lines between corner posts are obstructed (for example, a landowner fencing a large wooded plot who couldn’t see the next corner and feared misaligned boundaries).

PointPlot integrates what3words alongside coordinates, OS Grid References and natural-language search so every point and photo is tied to a precise 3‑word address; users can create plans made up of multiple surveys, mark points, view one survey while mapping another, and even build surveys from 3‑word inputs. The result is faster, more accurate on-site surveying—users can verify fence lines and property corners, streamline land measurements and simplify field-to-plan workflows.
