Member Function Documentation

void TerralibRaster::createRaster	(	const std::string &	str,
		int	categ = 0
	)		[virtual]

Open an existing raster file or a raster in a TerraLib database (read only).

Parameters:

str	TerraLib string pointing to the raster.
categ	if != 0 this is a categorical map (ie it can't be interpolated). Othewise this is a continuos map.

Needed by RasterFactory..

Implements Raster.

void TerralibRaster::createRaster	(	const std::string &	str,
		const MapFormat &	format
	)		[virtual]

Create a new file for projections.

Parameters:

str	TerraLib string pointing to the raster.
format	It is the output format specification.

Needed by RasterFactory.

Create a new file for projections.

Parameters:

file	is the name of the output file
format	is the output format specification.

Implements Raster.
