for navigation calculations.

Every list item should be a string of the form "UTMX,UTMY".

The returned area is in square Km.

n is the polygon's size.

UindxX and UindxY are the indices of the parameters UTMx and UTMy in the array.

The returned area is in square Km.

The calculated "straight line" is a Great Arc which is the shortest on a sphere.

the length of the total route in Km.

Every list item should be a string of the form "Lat,Long".

the length of a route which starts at point "start" and ends at "last".

GindxLat and GindxLong are the indices of the parameters Lat and Long in the array.

The result is in Km.

Parameters:

double a: Ellipsoid semi-major axis, in meters.

(For WGS84 datum, use 6378137.0)

double f: Ellipsoid flattening.

(For WGS84 datum, use 1 / 298.257223563).

int utmXZone:

Upon exit, this parameter will contain the hotizontal

zone number of the UTM coordinate.

The returned value for this parameter is a number

within the range 1 to 60, inclusive.

char utmYZone: Upon exit, this parameter will contain

the zone letter of the UTM coordinate.

The returned value for this parameter will be one of:

CDEFGHJKLMNPQRSTUVWX.

double easting: Upon exit, this parameter will contain

the UTM easting, in meters.

double northing: Upon exit, this parameter will contain

the UTM northing, in meters.

double lat, double lon: The lat/lon coordinate to convert.

The returned double array is in this order:

easting, northing ,utmXZone, utmYzone.

which is defined in the list parameter.

Every list item should be a string of the form "Lat,Long".

The returned area is in square Km.

n is the polygon's size.

GindxLat and GindxLong are the indices of the parameters Lat and Long in the array.

The returned area is in square Km.

from point 1 to 2.

The calculation is done as if the area is flat.

the length of the total route in Km.

Every list item should be a string of the form "UTMX,UTMY".

the length of a route which starts at point "start" and ends at "last".

UindxX and UindxY are the indices of the parameters UTMx and UTMy in the array.

The result is in Km.
