 org.geotools.coverage.processing.operation.Resample
| Resample | | public class Resample extends Operation2D (Code) | | Resample a grid coverage using a different grid geometry. This operation provides the following
functionality:
- Resampling
The grid coverage can be resampled at a different cell resolution. Some implementations
may be able to do resampling efficiently at any resolution. Also a non-rectilinear grid
coverage can be accessed as rectilinear grid coverage with this operation.
- Reprojecting
The new grid geometry can have a different coordinate reference system than the underlying
grid geometry. For example, a grid coverage can be reprojected from a geodetic coordinate
reference system to Universal Transverse Mercator CRS.
- Subsetting
A subset of a grid can be viewed as a separate coverage by using this operation with a
grid geometry which as the same geoferencing and a region. Grid range in the grid geometry
defines the region to subset in the grid coverage.
Geotools extension:
The
"Resample" operation use the default
org.opengis.referencing.operation.CoordinateOperationFactory for creating a
transformation from the source to the destination coordinate reference systems.
If a custom factory is desired, it may be supplied as a rendering hint with the
org.geotools.factory.Hints.COORDINATE_OPERATION_FACTORY key. Rendering
hints can be supplied to
org.geotools.coverage.processing.DefaultProcessor at construction time.
