Thanks JohnI'll have a lookbut yes my requirements are pretty
basic, so I was hoping there might be a UDF or some other custom doo-dad
to help me get it done ;-)
Cheers

I have to do this in an application and used this UDF:
http://www.cflib.org/udf/inPolygon
I think it performs the task you described.

Thanks for the tip Paul ;-)

Thanks Jochem,
This is still preliminary, but I assume these shapes are already defined
in a GIS system (which one I don't know).
I should be able to get the shape files (or data) that define these
areas, but may not have access to the GIS system itself (so can't use it
for comparison etc.).

lots of good info there!
Just to be clear, there would not be any visualization or anything
fancyjust checking to see if the point is in the box/shape or not -

no, but it can hurt like the dickens.

just use postGIS/postgreSQL. has tools to load shape
You might also take a look at the GIS capabilities that are now baked
into sever DB systems. MS SQL 2008 and the newer versions of PostGres
come to mind as having native support for geographic data. A lot of it
will come down to figuring out your actual requirements, which seem to
be rather fuzzy
Thanks Rob/Paul,
Rob, you confirmed what I thought.this shouldn't be rocket science.
Paul...yes I'd certainly prefer to let the right tool do the job.
This is an initial check to see what is available. I'm in no way
married to any ideas about what tools would be involved.
Currently, I can

Bryan,
Well it really sounds like what you need to do is the number crunching. Are
the coordinates going to be stored in a database? or read straight off of a
shape file lets say? All you really need to do is incrementally check your
bounds or your coordinate pairs to the location. You should
Hi All,
Quite new to GIS, but not CF..
I'm wondering if anyone has any advice on performing a task that
involves determining if a given lat/long is within a given oddly shaped
(not a simple rectangle) area/box?
I would assume the hard part is defining the boundaries of an irregular
shaped b
