Documentation (overview)
		The BALANS land cover dataset has been assembled
	from satellite data from the IRS 1C/1D WiFS satellite.
	The reference data has been collected from national
	sources. Note that the product is not homogenous due
	to that. The approach has been to produce the best possible
	product pixelwise within the frame of the BALANS project
	The quality of the product is still homogenous within
	a country though.
		From this the percentage of wetland cells, out
	of other cells that have been classified in the
	BALANS land cover classification have been calculated
	for 1500 x 1500 meter blocks. This is presented as
	integers in this dataset.
