Callback method for CURL when fetching data.

void RemoteRaster::createRaster	(	const std::string &	str,
		int	categ = `0`
	)

virtual

Open a raster (read only). Method needed by RasterFactory.

Parameters

str	WCS 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.

Reimplemented from GdalRaster.

void RemoteRaster::createRaster	(	const std::string &	str,
		const MapFormat &	format
	)

virtual

Create a new raster for projections. If called will throw an exception since the WCS driver in GDAL does not support creation. Method needed by RasterFactory.

Parameters
