Distance between municipalities:
The distances have been automatically calculated by obtaining the quickest route by means of an algorithm applied to the vectorial representation of the complete Gipuzkoa road network. The distances are taken to be as those between the municipality halls of each respective municipality and have been rounded up and down to kilometres.

You can use OpenStreetMap to calculate the route between two Gipuzkoa place names.
