Map pollution data as a HeatMap? -

-

i have route (or: list of points) associated weighted pollution value between 0 , 10. want map these points google maps.

the first thing came head use google maps heatmaplayer , weightedlocations. weights use pollution values , google maps rest me.

however, solution raises 1 issue: displayed heat (green-to-red color) depend on density of points. if 2 points close (and can case data), heat increase, irrespective of weight.

is there better solution create such pollution map google maps not take account density of points, takes account weight?
