A cadastral community is like a big imaginary puzzle piece that helps keep track of who owns different pieces of land in a certain area. Imagine you have a big cookie that you want to share with your friends. You might use a knife to cut the cookie into smaller pieces so that each of your friends can have a piece. That's kind of like what a cadastral community does - it divides up the land in an area into smaller pieces and keeps track of who owns each piece. This helps make sure that people don't accidentally build on someone else's land or try to claim ownership of land that doesn't belong to them. The cadastral community also keeps records of any changes made to the land, like when someone sells their piece to someone else. So, essentially, a cadastral community is like a big book of land ownership that helps keep everyone organized and playing fair.
