Sensors used by municipalities in public spaces should preferably be compulsorily included in a national sensor register. The Land Registry argues that.

Municipalities use sensors to collect information on parking behavior, crowding, temperature and noise, among other things. The basis for a sensor registry was developed by a partnership of municipalities, the Ministry of the Interior and the Land Registry.
"There is a lot of use of sensors in public spaces, both by business and government. But people are not always transparent about this. The register should change this," explains Marc van Andel of the Kadaster. For now, Amsterdam is the only municipality in the Netherlands with a reporting requirement for sensors.
Ronald Bokhove of the Land Registry explains why: "First, there is the financial picture. Who will pay for the whole rollout to a national sensor register? There is no clarity on that yet. Second, there are questions about governance. How are we going to govern the whole thing and who is ultimately responsible? And finally, one has to determine under which laws and regulations a national sensor registry can be built and managed."
"If there is going to be a national sensor registry, there must also be some certainties attached to it, such as timeliness and completeness of the data. And not only for the government, but also for the citizen. For maximum transparency, they will benefit from a complete map of the Netherlands on which all sensors can be found," van Bokhove said.
