The final source of pollution was determined by the location of graphics to identify specific coordinates, and this has affected to a certain extent, the source of pollution in the accuracy of data to allow case, you can find good models with a more precise calculation.

But to the final source of pollution position is through the graph determined the concrete coordinates, this has affected the source of pollution precision to a certain extent, in the data permission situation, may seek with the good model carries on a more precise computation.

But to the last position of the pollution sources is to determine the specific coordinates by graphics, which to a certain extent, affected the accuracy of the pollution sources, in the case of data allows, can find a good model for a more precise calculation.
