It is indeed super hard to collect or create better data. We were considering cooperation with indigenous lands non-profit https://native-land.ca/ that would be amazing! Do you know of a better source?
If you have tips for how to improve or data - please - post it via "Feebdack" button on the edge of the website for area and selected time...
To make this project well is super hard.
Is there a process to provide feedback and correct errors on the map?
