About the data
snoop compares successive snapshots of the official cadastral survey from swisstopo and derives each split, merge and new parcel from that comparison. A change is counted in the month it first appeared in the published data, so a month keeps its figure once it is out. Only municipalities with at least one change in the period have a page. For legally binding information, check the land register.
