"Web3. Perpendicular bisectors for each of the sides of the triangle are drawn and these bisectors form a polygon around each station. 4. The boundary of the catchment if it cuts the bisectors is taken as the outer Iimit of the polygon. Thus for station 1 the bounding polygon is abcd. For station (2) kade is taken as the bounding polygon. " - Other term of thiessen polygon
