You can point on a map for details, you do have to pay for details though, I've only use it for property, though I'm sure you can get details about land as well.
It's a nice comfortable bag, I bought one last year as i wanted a centre zip bag. I found it very warm. I agree with the comments about the zip and have found it quite sticky when fully zipped up ,however most of the time i've used it i havent had it fully zipped up. I think it has gone up...
