I was making a map of Alberta, Saskatchewan, and Alberta, thinking I would use a UTM projection, however, these provinces cover zones 12-16, so this likely isn't ideal. What other options are there?

  • Which application you are using ? – Shiko Oct 23 '16 at 4:42
  • What are your objectives: to preserve area? distance? cartographic appeal? – Aaron Oct 23 '16 at 6:35
  • I'm using ArcMap and trying to minimize distortion. – J. Doe Oct 23 '16 at 15:15

You could try Albers Equal Area Conic or Lambert Conformal Conic, they would be good choices.

If you choose Lambert, adust the central meridian to 105° west, and the parallels to 50°N and 60°N. Canada Lambert Conformal Conic

> Central Meridian -105°
> Standard Parallel 1 50°
> Standard Parallel 2 60°
> Latitude of Origin 40°

eg. Change the Coordinate System to Albers Equal Area and adjust central meridian. Data Frame Properities

  • Thanks! How did you figure out how much to adjust the central meridian (to 105 degrees west), and the parallels adjustment? – J. Doe Oct 24 '16 at 20:43
  • The central meridian is approximately in the middle of the three provinces. 60 deg N is the northern border of all provinces, the southern border is actually 49 deg so you could use that instead of 50. – Mattropolis Oct 24 '16 at 20:46
  • Thank you! If I use Albers Equal Area Conic, should I also adjust the central meridian? – J. Doe Oct 24 '16 at 20:51
  • Yes, I added an image to my answer. – Mattropolis Oct 24 '16 at 21:56
