<font size=3>For a system showing dynamic species distributino maps I am
looking for a way to count the number of points in each polygon of a
polygon layer. I am using MapScript to dynamically add the points from
data stored in MySQL. The polygon layer is a regular shapefile that can
either be a regular grid or a shapefile of countries or regions. Due to
the larger application this will be part of I am limited to MySQL and
won't be able to use PostGIS or any other spatial database. I could
probably loop through all points and polygon in MapScript and use the
$status = $polygon->contains($point); function, but considering
that there can be 100'000 or more points this can get really slow. Is
there any function that will do this? <br><br>
Thanks,<br><br>
