| Constructor Summary | |
| protected | Spheroid(Map properties, double radius, boolean ivfDefinitive, Unit unit)
Constructs a new sphere using the specified radius.
Parameters:
properties - Set of properties. |
| Method Summary | |
| public double | orthodromicDistance(double x1, double y1, double x2, double y2)
Returns the orthodromic distance between two geographic coordinates.
The orthodromic distance is the shortest distance between two points
on a sphere's surface. |
| Spheroid | | protected Spheroid(Map properties, double radius, boolean ivfDefinitive, Unit unit)(Code) | | Constructs a new sphere using the specified radius.
Parameters:
properties - Set of properties. Should contains at least "name".
Parameters:
radius - The equatorial and polar radius.
Parameters:
ivfDefinitive - true if the inverse flattening is definitive.
Parameters:
unit - The units of the radius value. |
| orthodromicDistance | | public double orthodromicDistance(double x1, double y1, double x2, double y2)(Code) | | Returns the orthodromic distance between two geographic coordinates.
The orthodromic distance is the shortest distance between two points
on a sphere's surface. The orthodromic path is always on a great circle.
Parameters:
x1 - Longitude of first point (in decimal degrees).
Parameters:
y1 - Latitude of first point (in decimal degrees).
Parameters:
x2 - Longitude of second point (in decimal degrees).
Parameters:
y2 - Latitude of second point (in decimal degrees). The orthodromic distance (in the units of this ellipsoid's axis). |
