Map Projections

ARMAP's web mapping applications and web services utilitze variations of the "North Pole Lambert Azimuthal Equal Area" map projection. The information below will be helpful to GIS users interested in the Arctic.

Projection	EPSG Code	Coordinate System Name
LAEA Alaska	3572	WGS_1984_North_Pole_LAEA_Alaska
LAEA Bering Sea	3571	WGS_1984_North_Pole_LAEA_Bering Sea
LAEA Canada	3573	WGS_1984_North_Pole_LAEA_Canada
LAEA North Atlantic / Greenland	3574	WGS_1984_North_Pole_LAEA_Atlantic
LAEA Northern Europe	3575	WGS_1984_North_Pole_LAEA_Europe
LAEA Russia	3576	WGS_1984_North_Pole_LAEA_Russia

ARMAP's web services support all of these map projections and more, but are currently only optimized for performance (cached) in LAEA Alaska.

Technical specifications are available in a detailed report.
