In cartometry, a special branch of cartography, a number of different methods have been developed to determine areas from maps. Maling (1989) specifies, among other things, area determination based on simple geometric figures, by comparison with standard figures, the square method, the method of counting the nodes of a square grid, the method of measuring by going around the edge of a territory (planimetrics), the weighing method.U kartometriji, posebnoj grani kartografije, razvijen je niz različitih metoda za određivanje površina s karata. Maling (1989) navodi, među ostalim, i određivanje površine na temelju jednostavnih geometrijskih likova, usporedbom sa standardnim likovima, metodom kvadrata, metodom brojenja čvorova kvadratne mreže, ...
