IN DUBIO PRO GEO Adjustment : Adjusting surfaces

Through given data points in 3D-space an adjusting (i.e. best fitting) surface (plane, sphere, ellipsoid or general quadric) is computed. Also a plane through 3 points, a sphere through 4 points etc. can be computed. Additional points may be projected onto the surfaces.

Note

Data points	Pointnames and three coordinates per point
Type of system: Column format:
	for first, second and third coordinate
	Pointnames and

for first, second and third coordinates
Points to be projected	Pointnames and coordinates
type & format as above 2D point: Find third coordinate such that point lies on the surface. 3D point: Find closest point on the surface and compute distance.	Suffix for names of projected points

Compute adjusting

1 more example

Forthcoming: : Use of grid systems, transfer of an adjustment model to for re-computation with extended options, degenerate quadrics, application of weights also to points to be projected
