I've come across the following coordinates:

x = 600907.76
y = 2437133

It's a coordinate located in Hawaii. I thought it was UTM, but the negative x coordinate makes me think otherwise. Anyone know what it should be?

    There are at least 5 State Plane coordinate systems for Hawaii and there's no reason to believe any of them are it. Where did you come across this? The actual source is always the best place to look, the evidence comes in many forms.

  • Sometimes in utm when you see a negative x they are using one zone adjacent to the right I think Jan 10, 2016 at 17:53
  • Good to know. I'll keep that in mind. Jan 10, 2016 at 17:54
