Dutch cycling and wandering source data available for our research
The Dutch Stichting Landelijk Fietsplatform and Stichting Wandelnet maintain a national route database with all national and regional cycling and wandering routes and networks (including e.g. all fietsknooppunten).
See: https://www.routedatabank.nl/menu/index.php
Through my contact at the Stichting we now got direct access to the source data if we want to use these data for our research, or the research of MSc and PhD students. You can obtain the username / password from me.
