Shape of the Earth (See Table 3.2) |
16 |
Scale factor of radius of
spherical Earth |
17-20 |
Scale value of radius of
spherical Earth |
21 |
Scale factor 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 |
Nj—number of points along a parallel |
35-38 |
Nj—number of points along a meridian |
39-42 |
La1 ― latitude of first grid point |
43-46 |
Lo1 ― longitude of
first grid point |
47 |
Resolution and component flags
(see Table 3.3) |
48-51 |
LaD — latitude(s) at which the Mercator
projection intersects the Earth (Latitude(s) where Di and Dj are
specified) |
52-55 |
La2 ― latitude of last grid point |
56-59 |
Lo2 — longitude of last grid
point |
60 |
Scanning mode (flags ― see Flag table 3.4) |
61-64 |
Orientation of the grid, angle between i
direction on the map and the Equator (see
Note1) |
65-68 |
Dj — longitudinal direction grid
length (see Note2) |
69-72 |
Dj ― latitudinal direction grid length
(see Note 2) |
Notes: 1. Limited to the range of 0 to 90 degrees; if the angle of orientation of the grid is neither 0 nor 90 degrees, Di and Dj must be equal to each other. 2. Grid lengths are in units of 10-3 m, at the latitude specified by LaD. |
