Spatial data variables are exported as maps, one for each year, in [[http://geotools.codehaus.org/GRASS+ASCII+Grid+format|Grass ASCII Grid]] or [[http://geotools.codehaus.org/ArcInfo+ASCII+Grid+format|ArcInfo ASCII Grid]] format (both very similar).

Together with the map a grass classification legend and a color legend is created ((To display the lagen in Grass just run the command d.legend))
(we use [[http://grass.itc.it|grass]] for display and/or analyse the data).
