In advanced GIS modeling, if one needs to model the *potential* influence of scattered pollution sources across an entire watershed area, which technique moves beyond simple proximity checks?

Question

Accepted Answer

Employing spatial interpolation (like IDW) on measured concentration data.. Interpolation estimates values across unmeasured space, which is necessary when modeling continuous phenomena like pollutant spread from discrete sources.
