All of these datasets are held in geographicals, i.e. latitude and longitude. This allows users to projection data on the fly to a suitable projection. These projections are conformal, that is, they preserve shape and angles over small areas. When working with precise referencing and directional relationships, it is necessary to develop a plane coordinate system, preferably one that is conformal. The Polar Stereographic is a planar perspective projection where the south pole is viewed from the north pole.
True scale is represented along the standard parallel.
The true scale equals 0 if the plane is tangential to the Earth's surface at latitude 90 . Projection parameters used to define the Polar Stereographic Projection Polar Stereographic Projection and the appearance of the graticule. It is not possible to project a dataset from geographicals to polar stereographic using a standard parallel of 71 S on the fly using ESRI's ArcView 3.2 software. Users who want to map using this projection must hold their data in this projection, i.e. not project on the fly. The Universal Transverse Mercator is a cylindrical projection made up of sixty zones which cover the globe.
