data_date Unknown
description Land cover data obtained from the Swedish National Land
Survey. For each 500 m by 500 m pixel the landcover is
given as one of the following classes: forested, unforested
or water. To increase the information SMHI have combined
these data with their own data base on lakes.

For hydrological purposes Sweden has been divided into a
number of so called standard basins with a mean size of
approximately 40km2 (about 10000 basins). The land cover
database has been used to compute the forested, the
unforested and the lake areas for each standard basin.
This information is stored in a separate data base.

This standard basin data base does not at present contain
information on glaciers. Digitized information on
glaciers is available, although this information has not yet
been combined with the standard basin database. SMHI
entered the data on glaciers into the HBV model
files by hand, but using the areas from the digital data
base.
