Detailed Description

This class extends the MapDataSet base type for a polar- stereographic projection. It encapsulates a rectangular area of interest that can be located anywhere on the X-Y plane of the map. The implementation is based on two coordinante systems. The first is a standard Cartesian coordinate plane. The origin of the X,Y axes represents the north or south pole (depending on the hemisphere used), with the X-axis along the base longitude of the MDS (positive to the right) and the Y-axis completing a right-handed coordinate system (positive upward). Any latitude line forms a circle around the pole (origin), with the equator being the outmost such circle. Any longitude line is a straight line from the pole to a point on the equatorial circle.
Eastward motion is counterclockwise (for the northern hemisphere) or clockwise (for the southern hemisphere) along any cirlce of latitude. The second system consists of the row-column coordinate plane of the MDS rectangle. The center of the upper- left pixel is at the origin (row 0, column 0) for the convenience of other software already in use. WIth row #'s increasing downward and cloumn #'s increasing to the right, this is actually another right-handed Cartesian coordinate system in the map plane. The common relationship between the two coordinate systems is that the X-axis is parallel to the top of the MDS rectangle. Also note that it does not matter whether the long
side of the rectangle is considered left-right or top-down.
