Grid 8: Albers equal-area, secant or tangent, conic or bi-polar
Grids
| Octets | Key | Type | Content |
| 7-8 | Nx | unsigned | Nx number of points along x-axis |
| 9-10 | Ny | unsigned | Ny number of points along y-axis |
| 11-13 | latitudeOfFirstGridPoint | signed | La1 latitude of first grid point |
| 14-16 | longitudeOfFirstGridPoint | signed | Lo1 longitude of first grid point |
| 17 | resolutionAndComponentFlags | codeflag | Resolution and component flags (see Code table 7) |
| 18-20 | LoV | unsigned | LoV orientation of the grid; i.e. the east 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) |
| 21-23 | DxInMetres | unsigned | Dx x-direction grid length (see Note (2)) |
| 24-26 | DyInMetres | unsigned | Dy y-direction grid length (see Note (2)) |
| 27 | projectionCenterFlag | unsigned | Projection centre flag (see Note (5)) |
| 28 | scanningMode | codeflag | Scanning mode (flags see Flag/Code table 8) |
| 29-31 | Latin1 | unsigned | Latin 1 first latitude from the pole at which the secant cone cuts the sphere |
| 32-34 | Latin2 | unsigned | Latin 2 second latitude from the pole at which the secant cone cuts the sphere |
| 35-37 | latitudeOfSouthernPole | signed | Latitude of the southern pole in millidegrees (integer) |
| 38-40 | longitudeOfSouthernPole | signed | Longitude of the southern pole in millidegrees (integer) |
| 41-42 | Set to zero (reserved) |
( 1) Latitude and longitude are in millidegrees (thousandths of a degree).
( 2) Grid lengths are in units of metres, at the secant cone intersection parallel nearest to the pole on the projection plane.
( 3) Latitude values are limited to the range 0-90 000; bit 1 is set to 1 to indicate south latitude.
( 4) Longitude values are limited to the range 0-360 000; bit 1 is set to 1 to indicate west longitude.
( 5) Octet 27 (projection centre flag):
bit 1 set to 0 if North Pole is on the projection plane
bit 1 set to 1 if South Pole is on the projection plane
bit 2 set to 0 if only one projection centre is used
bit 2 set to 1 if projection is bi-polar and symmetric.
( 6) If Latin 1 = Latin 2, then the projection is on a tangent cone.
( 7) The resolution flag (bit 1 of Code table 7) is not applicable.
