=== Description === | ===Description=== | ||
Both datasets were "compiled by Finnish Meteorological Institute (<nowiki>http://en.fmi.fi/</nowiki>) based on weather service observations on sea ice extent in the Baltic Sea from satellite observations (2005-2009). The maximum ice extent map shows the areas which were at least once covered by ice within the study period. The minimum ice extent map displays the area which was covered by ice in every year of the study period. The maps were derived by digitizing existing ice extent maps to picture format and then to GIS shapefiles. Due to this reason the ice extent area should be considered as indicative especially within coastal areas. For further information, see http://www.iceservice.fi/." | |||

Both layers were combined in one layer only that depict the maximum and minimum ice coverage. The geometries were simplified to optimise rendering in the game engine. | Both layers were combined in one layer only that depict the maximum and minimum ice coverage.
