Class RasterLayer

java.lang.Object

repast.simphony.space.gis.RasterLayer

public class RasterLayer
extends Object

RasterLayer provides Repast ValueLayer like functionality using geographic coordinates and can be displayed when part of a Geography instance. Contains an instance of a WritableGridCoverage2D that allows read and write capabilities on an underlying GridGoverage2D. Current write capability is limited to a single band. The WritableGridCoverage2D needs to be updated to allow multi-band writes. TODO GIS provide multiple band write capability.

Constructor Details

RasterLayer

public RasterLayer(String name,
 org.geotools.coverage.grid.GridCoverage2D gridCoverage)

Create the RasterLayer from the provided GridCoverage2D. This is useful when creating GridCoverage2D from other readers or data types.

Parameters:

name -

gridCoverage -

RasterLayer

public RasterLayer(org.geotools.coverage.grid.GridCoverage2D gridCoverage)

RasterLayer

public RasterLayer(String name,
 File rasterfile)

RasterLayer

public RasterLayer(String name,
 File rasterfile,
 boolean forceLonLatAxisOrder)

Create the RasterLayer using a raster file. The coverage returned by the file reader will be wrapped with a WritableGridCoverage instance so that this layer can be written to.

Parameters:

name - the name of the GeoValueLayer

rasterfile - a georeferenced raster file such as GeoTif

forceLonLatAxisOrder - forces lon,lat coordinate order on read
