Hi,

A request from an ecologist has turned into a bit of a mission for me. I'm looking to count the number of unique points within a polygon. This is to assess the number of unique species sightings within an area and not just the total number of sightings. Surely there is an easy way to do this at the desktop level? I can do it at the DB level but want to leave the ecologist with a method they are comfortable with.

Thanks!
Andy, Dublin, Ireland
