+1, I'd extend this to "do not get arrested", "do not get fined", "do
not break local law" (where local is referring to the country from
which the mapper is operating, not the country which he is mapping).

-1, you might map the sign as "toy factory" (maybe I am
misinterpreting what you said? I never met a building that "said"
something ;-) ) but if _on the ground_ it is a military installation
and you ("everyone") know about this, mapping it as a toy factory
would be plain wrong and also a violation of the on the ground rule.

you might map it like this if it is not forbidden in your country to
do so (but in many/most countries it will indeed be forbidden to map
military installations).

I guess that in many jurisdictions it would be less safe to map
something that you can only see from the public road (i.e. locally) in
respect to something you can derive from an aerial image publicly
available (i.e. globally).

> If these areas are mapped it's helpful so you can avoid hiking through them.

usually there would be measures taken to prevent you from hiking
through those areas anyway ;-)
