package org.apache.sis.referencing.operation.builder
Helper classes for creating Math Transforms from a set of points. The builder classes require a matched set of known positions, one from a "source" data set and another from a "target" data set. The builder will then provide a transformation positions from the "source" CRS to the "target" CRS.

Algorithms in this package use a least squares estimation method. The matching parameters are estimated by minimizing the sum of the squared distances between the given points and the fitted points (i.e. the points calculated using the transform). Note that "distance" here is not necessarily the Euclidian distance or a geodesic distance. It may be an approximation of Euclidian distance for implementation convenience.
