GeoEllipsoid
This struct provides properties for a particular World-Ellipsoid. It is defined by ist two radii: "a" and "b".
Constructors
| Constructor | Description |
new(a, b, f)
Signature: (a:float * b:float * f:float) -> unit
|
Construct a geo-ellipsoid from semi-major axis a (bigger radius), semi-minor axis b (smaller radius) and flattening f. Since only two of these are necessary for specification, use the static functions and to construct ellipsoids given their defining parameters. |
Instance members
| Instance member | Description |
E2Q
Signature: float
|
Returns the second eccentricity squared: e2^2 = (a^2-b^2)/b^2. |
EQ
Signature: float
|
Returns the first eccentricity squared: e^2 = (a^2-b^2)/a^2. |
InvF
Signature: float
|
Returns the inverse of the flattening: 1/f. |
Static members
| Static member | Description |
FromAB(a, b)
Signature: (a:float * b:float) -> GeoEllipsoid
|
|
FromAF(a, f)
Signature: (a:float * f:float) -> GeoEllipsoid
|
