Here are a couple of maps that show places around Port Isaac where they have filmed street scenes.  
The red circles contain the series number (1 - 7) when they filmed in that location.  You can see that
there are several locations that have been used in every series.

The two red boxes contain a lot of filming areas and you can see the details in the detail maps below.
