What is the actual update frequency of GWR-RegBL-REA? Presumably it varies by canton/location and type of feature.
It haven’t found a building in Geneva that isn’t in there, but for other places, buildings can be visible on Swisstopo aerial images, but still not in there.
On the other hand, there are occasionally streets or squares in there, that don’t exist, that have been renamed or will be renamed.
