Draw on Google Maps
free — with real measurements.
Terramapr gives you a full drawing layer on top of Google Maps satellite imagery. Draw any shape, measure the area and perimeter, and save your work — free, in any browser, no install required.
Google Maps lets you drop a pin or get directions. It doesn't let you draw a polygon and measure it. Terramapr fills that gap: a proper drawing tool built on top of real Google Maps satellite data. Draw polygons with automatic area measurement, draw lines with length readout, add markers with labels.
Every shape you draw is measured geodetically — accounting for the curvature of the earth. A 10 ha farm measured with a flat-map approximation can read up to 3% wrong. Terramapr gives you the accurate number.
Works for any use case: farm planning, property layout, site planning, landscape design, fence quoting. Draw the area, read the number, make the decision. Start in the live demo with no account.
