There are laws making it illegal to collect data on open land

7. My opinion on the law changes whether the "open land"

in question is public versus private property.

No private citizen generally has the right to go onto someone else's property without permission, regardless of the purported good intentions.

If someone suspects illegality, report it to the relevant authorities who can seek a court order (or use existing legislative or executive authority) for inspections or other appropriate investigative and remedial procedures.
