The invention discloses a method and system for constructing an electromagnetic map based on weight distribution, and belongs to the technical field of image data processing. The method comprises the following steps: deploying a plurality of sensing nodes in a target area to obtain a sensing matrix, obtaining electromagnetic observation data of the target area through sampling, and constructing electromagnetic related data of an electromagnetic map based on the sensing matrix and the electromagnetic observation data; the method comprises the following steps: acquiring geographical sampling data of a target area through sampling on the basis of a plurality of deployed sensing nodes, and predicting geographical correlation data of an unsampled position according to geographical correlation among the geographical sampling data so as to obtain geographical correlation data of an electromagnetic map; weights are assigned to the electromagnetic related data of the electromagnetic map and the geographically related
