Grid Definition Template 3.20 - Polar stereographic projection



Octet No.	Contents
15	Shape of the earth (see Code Table 3.2)
16	Scale factor or radius of spherical earth
17-20	Scaled value of radius of spherical earth
21	Scaled value of major axis of oblate spheroid earth
22-25	Scaled value of major axis of oblate spheroid earth
26	Scale factor of minor axis of oblate spheroid earth
27-30	Scaled value of minor axis of oblate spheroid earth
31-34	Nx - number of points along X-axis
35-38	Ny - number of points along Y-axis
39-42	La1 - latitude of first grid point
43-46	Lo1 - longitude of first grid point
47	Resolution and component flags (see Flag Table 3.3 and Note 1, below)
48-51	LaD - Latitude at which Dx and Dy are specified
52-55	LoV - orientation of the grid (see Note 2, below)
56-59	Dx - X-direction grid length (see Note 3, below)
60-63	Dy - Y-direction grid length (see Note 3, below)
64	Projection center flag (see Flag Table 3.5)
65	Scanning mode flag (see Flag Table 3.4)


Notes:

(1) The resolution flag (bit 3-4 of Flag Table 3.3) is not applicable.

(2) LoV is the longitude value of the meridian which is parallel to the Y-axis (or columns of the grid) along which latitude increases as the Y-coordinate increases (the orientation longitude may or may not appear on a particular grid).

(3) Grid length is in units of 10^-3 m at the latitude specified by LaD.

(4) Bit 2 of the projection flag is not applicable to the polar stereographic projection.
