Thanks Noli. The approach I took was (following a hint from Alex from "Wild Intellect") was:
1. to make a new shape file from my yellow polygon, (Layer > Save Selection as Vector file ...) 2. importing the new layer and placing the "dots" layer above the new layer, then 3. Vector>Research Tools>Select by location... and follow the GUI instructions This did exactly what I needed. A great tool! best regards, Nick From: Noli Sicad <[email protected]> To: [email protected] Cc: [email protected] Date: 25/01/2011 03:18 PM Subject: Re: [Qgis-user] Intersection between vector layers Hi Nick, I think there are two ways to accomplish this, 1, Select the yelllow polygon using the "Select Features" tool then Tools > Geoprocessing Tools > Intersect. Create a new shapefile in "Output Shapefile" and "OK" or 2. Using the "Select Features" tool again, Press Control button, select all the points in inside the polygon and then Tools > Geoprocessing Tools > Clip. Create a new shapefile in "Output Shapefile" and "OK" Noli On 1/25/11, [email protected] <[email protected]> wrote: > Hi Noli, > > Thanks for your email. > > I attach the screen grab. > > The small circles (aka 'dots') are all on one layer.
