| ProjectionAnalyzer | | final class ProjectionAnalyzer (Code) | | Returns a conversion from a source to target projected CRS, if this conversion
is representable as an affine transform. More specifically, if all projection
parameters are identical except the following ones:
Then the conversion between two projected CRS can sometime be represented as a linear
conversion. For example if only false easting/northing differ, then the coordinate conversion
is simply a translation.

| Method Summary | |
| public static Matrix | createLinearConversion(ProjectedCRS sourceCRS, ProjectedCRS targetCRS, double errorTolerance)
Returns a conversion from a source to target projected CRS, if this conversion
is representable as an affine transform. |
| createLinearConversion | | public static Matrix createLinearConversion(ProjectedCRS sourceCRS, ProjectedCRS targetCRS, double errorTolerance)(Code) | | Returns a conversion from a source to target projected CRS, if this conversion
is representable as an affine transform. If no linear conversion has been found
between the two CRS, then this method returns
null .
Parameters:
sourceCRS - The source coordinate reference system.
Parameters:
targetCRS - The target coordinate reference system.
Parameters:
errorTolerance - Relative error tolerance for considering two parameter values asequal. This is usually a small number like 1E-10 . The conversion from sourceCRS to targetCRS as anaffine transform, or null if no linear transform has been found. |
