5.6.6 GM_CalcCenterAndRadius
Description Calculation of centre coordinate and radius result from 3 points.
Declaration
GM_CalcCenterAndRadius(
Pt0 AS GM_Point_Type,
Pt1 AS GM_Point_Type,
Pt2 AS GM_Point_Type,
dRadius AS Double,
Center AS GM_Point_Type,
dMRadius AS Double )
Remarks This function is calculating the coordinate of the centre and the
radius result from 3 given points.
Note Used formula: see Appendix, Geodesy Math. Formulas.
Parameters
Pt0 in
contains the coordinate and the exactness
of the 1. point
Pt1 in
contains the coordinate and the exactness
of the 2. point
Pt2 in
contains the coordinate and the exactness
of the 3. point
dRadius out
calculated radius [m]
Center out
calculated coordinates and exactness of
the centre
dMRadius out
middle error of the radius [m]
Return Codes
GM_PTS_IN_LINE
The 3 points are located on one line, the
calculation not possible. All output values
are undefined.
