Transverse Mercator Zoned Grid System projection (EPSG codes 9824).
This projection is valid for all the world in a given hemisphere, except the poles.
The Earth is divided into zones, usually 6° width. The zone number is determined
automatically from the longitude and is prefixed to the Easting value.
This map projection is not suitable for geometric calculations like distances and angles, since there is discontinuities (gaps) between zones. Actually this operation is not handled as a map projection by Apache SIS, as can be seen from the different class hierarchy.
Note:
current implementation can only be backed by the Transverse Mercator projection,
but future versions could apply to some other projections if needed.
Examples of CRS using this projection are WGS 84 / UTM grid system EPSG:32600 (northern hemisphere) and EPSG:32700 (southern hemisphere).

getParameterValues
Returns the parameter values of this zoned grid system projection.- Specified by:
getParameterValuesin interfaceParameterized- Overrides:
getParameterValuesin classAbstractMathTransform- Returns:
- the internal parameter values for this zoned grid system projection.
- See Also:
-
getDomain
Returns the domain of input coordinates. The limits defined by this method are arbitrary and may change in any future implementation. Current implementation sets a longitude range of ±180° (i.e. the world) and a latitude range from 84°S to 84°N.- Overrides:
getDomainin classAbstractMathTransform- Parameters:
criteria- controls the definition of transform domain.- Returns:
- estimation of a domain where this transform is considered numerically applicable.

transform
public Matrix transform(double[] srcPts, int srcOff, double[] dstPts, int dstOff, boolean derivate) throws TransformException Projects the specified (λ,φ) coordinates and stores the result indstPts. In addition, opportunistically computes the projection derivative ifderivateistrue. Note that the derivative does not contain zone prefix.- Specified by:
transformin classAbstractMathTransform- Parameters:
srcPts- the array containing the source coordinates (cannot benull).srcOff- the offset to the point to be transformed in the source array.dstPts- the array into which the transformed coordinates is returned. May be the same thansrcPts. May benullif only the derivative matrix is desired.dstOff- the offset to the location of the transformed point that is stored in the destination array.derivate-truefor computing the derivative, orfalseif not needed.- Returns:
- the matrix of the projection derivative at the given source position,
or
nullif thederivateargument isfalse. - Throws:
TransformException- if the coordinates cannot be converted.- See Also:
-
inverse
Returns the inverse of this map projection.- Specified by:
inversein interfaceMathTransform- Specified by:
inversein interfaceMathTransform2D- Overrides:
inversein classAbstractMathTransform2D- Returns:
- the inverse of this map projection.

computeHashCode
protected int computeHashCode()Computes a hash code value for thisZonedGridSystem.- Overrides:
computeHashCodein classAbstractMathTransform- Returns:
- the hash code value.
-
equals
Compares the given object with this transform for equivalence. If this method returnstrue, then for any given identical source position, the two compared map projections shall compute the same target position.- Specified by:
equalsin interfaceLenientComparable- Overrides:
equalsin classAbstractMathTransform- Parameters:
object- the object to compare with this map projection for equivalence.mode- the strictness level of the comparison. Default toComparisonMode.STRICT.- Returns:
trueif the given object is equivalent to this map projection.- See Also:
