Dear all
I am trying to do something which should be straightforward but can't
quite manage and any suggestions would be appreciated.
I have geo-referenced a largish point file (13,500 records) against a
large polygon file (c9000) polys. In most cases the points produce
represent one record per poly but for a number of the polys there are
between 2-250 records 'hidden' behind the visible point. I've used
disperse to get a more detailed map but what I really want to do is to
find a way of counting the number of points within each poly and add the
results as a new column in the poly file ( so I can produce choropleths
of the true numbers in each poly). Any suggestions on how to do this -
if you're confused by the question let me know and I'll try and simplify
it - i suspect it may be a cleverly produced sql query ??
any help gratefully received,
ronan foley
