Section 3 - Template 41 : Rotated Gaussian latitude/longitude

Octets Key Type Content
15-72 Same as Grid Definition Template 3.40 (see Note 1)
73-76 latitudeOfSouthernPole signed Latitude of the southern pole of projection
77-80 longitudeOfSouthernPole unsigned Longitude of the southern pole of projection
81-84 angleOfRotation real Angle of rotation of projection
85-nn pl unsigned List of number of points along each meridian or parallel (These octets are only present for quasi-regular grids as described in note 4)
Notes:

( 1) Basic angle of the initial production domain and subdivisions of this basic angle are provided to manage cases where the recommended unit of 10-6 degrees is not applicable to describe the extreme longitudes and latitudes, and direction increments. For these last six descriptors, unit is equal to the ratio of the basic angle and the subdivisions number. For ordinary cases, zero and missing values should be coded, equivalent to respective values of 1 and 106 (10-6 degrees unit).

( 2) The number of parallels between a pole and the equator is used to establish the variable (Gaussian) spacing of the parallels; this value must always be given.
