I have two data sets: one for Thurston County, Washington and one for all of Washington state. I created a map of hydrology features in Thurston County, and now I want to take the data from the Washington state data set and overlay it on top of the Thurston County data set, so that all of the WA state data points inside the county boundary are added, but nothing else is. How would I do this in ArcGIS or QGIS?
I'd be interested in instructions on how to do this, but just knowing if there is a name for this type of operation so I can search for more references would be helpful.
