Fact & precision ? Multiple contributors ?

How precise need a fact to be so that it becomes a fact ? The GPS positionning is precise up to a certain limit. Plus there are potential issues (hardware, user errors, etc..) that make the data in the database unique.

Think about a group of painters trying to reproduce a landscape, each with different tools. Althought the end result might be very similar to the reality (the facts), it could be slightly different enough to be seen as a creation. Futhermore, as the work is always in progress and uses so many contributors make it a special case. It's not like the creation was directed/controlled and the current result (a sub set of the reality) is some sort of community art. Or do we need changes in the law to manage those community gathered 'facts' ?

Finally: what about using colors to represent the GPS positions ? :) Or losing some precision/introducing small errors voluntarily in order to make the result a creation ?
