Class GridHorizCoordSys

java.lang.Object
  ucar.nc2.iosp.grid.GridHorizCoordSys

public class GridHorizCoordSys
extends java.lang.Object

A horizontal coordinate system created from a GridDefRecord

Note on "false_easting" and "fale_northing" projection parameters:

• false_easting(northing) = The value added to all x (y) values in the rectangular coordinates for a map projection. This value frequently is assigned to eliminate negative numbers. Expressed in the unit of measure identified in Planar Coordinate Units.
• We dont currently use, assuming that the x and y are just fine as negetive numbers.
