All data sets are downloadable as compressed files in ZIP-format; each ZIP-file contains both documentation and data files. Please refer to the viewable metadata files and to the General Comments section at the bottom of this page for additional information about data files. Information about projection is at the bottom as well.
For additional datasets, see also the 'related data' page.
If you have difficulties
downloading (large) files, you may alternatively order
a CD-ROM containing the same data.

All data sets in the Baltic Sea drainage basin database were re-projected onto the Lambert Azimuthal Equal Area projection system using the following coordinates:
Upper right corner: X = 1,000,000
, Y = 1,300,000
Lower left corner: X = -1,000,000
, Y = -1,300,000
Most images are converted into Byte/packed binary (run-length encoded) format. In some cases, images were converted into Integer format because values exceeded 256. Please refer to the metadata files for more specific information.
Images and associated metadata files were PKzipped with Version 2.04g.
PLEASE NOTE: The Administrative Units data set is not provided as an IDRISI image file due to its size (500 meter resolution = 40 MB). Instead, it is provided as an IDRISI vector file. Please read the following section for conversion instructions.
