Hello All,
Can anyone tell me whether there is a way to count up the number of point objects from
one table that are contained within certain regions in another layer. I have a table
of points which are particle positions from the output of a model. I also have a grid
which makes up many rectangular regions over the area. I want to count the number of
particles contained within each grid section so that I can thematically map the
result. I could do this by changing my model so that it does the calculation before
outputing the point positions but this may take a lot of time and I was wondering if
there is an easier way via mapinfo.
Alternatively, I could make up regions from a grid which can have differing lon and
lat increments so that the mapinfo grid can each time match the grid from my model. I
can't find a way to do this either as the gridmaker always keeps the grid spacing the
same in x and y.
Any help would be greatly appreciated
Thanks very much
Elliot Tinton.
