All MapInfo data sets below
have kindly been prepared by Mr.
Mats Elfstrom, from the ArcInfo data sets found on this web site. The
data sets are downloadable as compressed files in ZIP-format created using
WinZip v7.0. Each ZIP-file contains data files along with a *.txt file
with the extracted header from the MIF file. Regarding additional metadata,
please refer to (1) the corresponding ArcInfo metadata
files, and (2) the general MapInfo readme.txt file
prepared by Mr. Mats Elfstrom,
located at the bottom of this page.

The ARC/INFO e00 files found
under http://www.grida.no/baltic/htmls/arcinfo.htm were used as input data.
As MapInfo does not support
the Lambert Azimuthal Equal Area projection other than in a polar aspect,
a new co-ordinate system was created and added to the MAPINFOW.PRJ file.
The parameters used for this are:
"Equal-Area Projection (GRID-A)",
9, 28, 7, 20, 60, 55, 65, 0, 0
(the above line can be pasted
into the file, under the heading 'Regional Equal-Area Projections'). The
variables are:
9 = projection, Albers Equal-Area
Conic
These parameters gave the best
results compared with the MapInfo standard world map. Thus, it is possible
to view the Baltic GIS data along with other projected data sets. A "small"
error (< 10 km) persists, notably in the far corners of the area.
All of the e00 files content
was converted. Some unmappable datafiles, and the tic files were excluded
from further processing. If needed, these files can be downloaded as datafile.zip
and ticfile.zip, respectively; the
e00 file names are retained.
For the rest of the data, further
editing was undertaken.
Each zip-file contains a MID/MIF
file pair, along with a *.txt file with the extracted header from the MIF
file. The MID/MIF file can be imported into a MapInfo table using the MapInfo
import command.
Administrative Units
The Administrative Units data
consists of a zip-file that contains a MID/MIF file pair, along with a
*.txt file with the extracted header from the MIF file.
Arable Lands
The Arable Lands data consists
of a zip-file that contains a MID/MIF file pair, along with a *.txt file
with the extracted header from the MIF file.
Land and Ocean (Coastline)
The Land and Ocean (Coastline)
data consists of a zip-file that contains a MID/MIF file pair, along with
a *.txt file with the extracted header from the MIF file.
Land Cover
The Land Cover data consists of
a zip-file that contains a MID/MIF file pair, along with a *.txt file with
the extracted header from the MIF file. For an updated dataset, with a higher resolution, see the 'related data' page.
Pasture Lands
The Pasture Lands data consists
of a zip-file that contains a MID/MIF file pair, along with a *.txt file
with the extracted header from the MIF file.
Population Density
The Population Density data consists
of a zip-file that contains a MID/MIF file pair, along with a *.txt file
with the extracted header from the MIF file.
Sub-watershed Drainage Basins
The Sub-watershed Drainage Basins
data consists of a zip-file that contains a MID/MIF file pair, along with
a *.txt file with the extracted header from the MIF file.
Wetlands Distribution
The Wetlands Distribution data
consists of a zip-file that contains a MID/MIF file pair, along with a
*.txt file with the extracted header from the MIF file. For an updated dataset, with a higher resolution, see the 'related data' page.
readme.txt
- MapInfo files.
The MapInfo files were
converted with ArcLink v3.1.4, which is shipped with MapInfo Professional
v4.5.2.
28 = datum, European 1950
(ED50)
7 = units, meter
20 = origin long
60 = origin lat
55 = Standard parallel 1
65 = Standard parallel 2
0, 0 = false easting and northing,
not used
The MIF/MID files were compressed
using WinZip v7.0 SR-1
