I have multiple files each loaded as a layer. Each file has just an easting northing and a count value, as below.
easting,northing,count 435575,804275,15 435625,804225,29 435625,804275,39 435625,804325,53 435675,804075,8 435675,804125,11 435675,804175,45 435675,804225,60 435675,804275,81 435675,804325,117 435675,804375,83 435725,804025,16 435725,804075,21 435725,804125,64 435725,804175,76 435725,804225,113
All the easting and northing points are on the same 50m x 50m grid.
I have used the count value to colorize this data, selecting a 50m square though the geometry manager which looks good for each layer in isolation.
What I can't work out how to do is :
These layers overlap each other. Where they overlap each other I would like to sum the count from each point at the same easting and northing position, to produce a single data set.
