Lambert Conformal Conic Projection Parameters dialog

In order for your scanned map to display correctly, ExpertGPS needs to know the details of the projection used when the map was printed. This information should be printed in the margin or a corner of your map.

Lambert Conformal Conic Projection Parameters
Standard Parallels
Enter the latitude of the two standard parallels, in degrees and decimal minutes.
Central Meridian
Enter the longitude of the central meridian. This is the only line of longitude on the map that is vertical. All other meridians are at an angle.

Tip

  • If the Central Meridian is not explicitly listed in the map margin, determine the line of longitude that is vertical on the map. In the example below, the 0º and 20º East lines of longitude slope away from the vertical at the same angle. Therefore, the vertical Central Meridian lies halfway between them, at 10º East.
