| Sep 4, 2015 at 1:44 | comment | added | PolyGeo♦ | I was told many years ago, in South Australia where Port Pirie straddles a zone boundary, that as long as the data did not go further than 30 minutes into an adjacent zone then it was perfectly acceptable to treat that adjacent data as if it was in the main zone and project it into that false zone. | |

| Sep 3, 2015 at 23:24 | comment | added | Michael Stimson | I don't know if the USGS Quad maps have a specification that discusses this, I haven't had much to do with them. I'd say they do it for convenience. I used to make 250k maps, with a zone change on the ephemera it was a right pain to add a new grid/graticule and project the data. Nowdays I would use the zone for the majority of the data and continue the same zone over an edge - so long as you don't go too far the distortion isn't too bad. If you're going well into an adjacent zone it's time to think about non-UTM projections like Albers Equal Area or Lamberts... | |
