One reason for the large numbers is that so when data is imported into a drawing it is immediately obvious whether it shares the same coordinate system. If multiple sets of points from different disciplines are imported into the program then the draftsman knows whether the coordinate systems are the same by visual inspection (to a rough degree).
Also because nobody wants to use negative numbers or have the possibility of a negative number showing up.
- pavlov 6y ago> “... nobody wants to use negative numbers” It’s hard to understand these priorities. An unholy mix of base-12 and base-16 is fine, but negative numbers are too difficult to work with?
- abduhl 6y agoWhen you’re working with a couple guys who probably went on a bender last night out in the middle of nowhere with no cell service and a piece of shit walkie talkie that has spotty transmission you sometimes end up having to throw up hand signs to signal northing and easting values. There’s no hand signal for negative. So yeah, negative numbers are hard to work with in that case.
