Surveying & Land Tools

Almost no plot of land is a rectangle, yet almost every quick area formula assumes one. Land Area Calculator drops that assumption: list the corners as coordinates, or walk the boundary leg by leg with a bearing and a length for each side, and the shoelace formula returns the enclosed area however irregular the outline is. Results arrive in square metres and feet alongside acres, hectares, square yards, decimal, katha and bigha, with each local unit stating the definition it used.

Geodetic Distance Calculator sits here too, from GIS & Mapping, since the distance between two marks is the other half of a survey. Levelling reductions, traverse adjustment, cut and fill, curve radius, road gradient and earthwork volumes are what this page grows into.
