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 and add the count 
to a table.   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 and add the 
result as a column in the table 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.
