What projections are used for gridded Operation IceBridge data sets?

This article describes the Arctic and Antarctic projections used for gridded Operation IceBridge data sets.

Arctic

The standard projection parameters for Northern Hemisphere Operation IceBridge data are:

  • Polar Stereographic
  • Standard Parallel 70° N
  • Longitude of the origin (central meridian): 45° W
  • WGS 84 ellipsoid

This projection is defined as EPSG:3413. Examples of other NSIDC DAAC data sets using this projection include:

Antarctic

The standard projection parameters for Southern Hemisphere IceBridge data are:

  • Polar Stereographic
  • Standard Parallel 71° S
  • Longitude of the origin (central meridian): 0°
  • WGS 84 ellipsoid

This projection is defined as EPSG:3031. Examples of other NSIDC DAAC data sets using this projection include:
