If I provide a topographic product, I require a signed form that basically states:Sometimes a topic can bring up a side issue, that is extremely important. It is because of this I placed a disclaimer on my website regarding images that we provide...though I've not been approached by any licensing authority, its just a CYA (as best I can) so there's no mistaking any representation of usability.
- We are not a licensed surveyor
- We are not representing the data as accurate to any measure
- The client is using the data at their own risk
- Full stop
They seem to find the data usable and sufficient and come back again !
