English Abstract A table has been constructed to make transformations
between the following regionalizations: acidification regions, agricultural
regions, EXPECT-ecodistricts, EXPECT soil type, EXPECT groundwater type and
EXPECT landuse type. These regionalizations cover the main input and output
regionalizations for the EXPECT models. The table has been constructed as
an attribute table of a grid map with cell size of 500 x 500 meter, which
covers the whole terrestrial part of the Netherlands. The total number of
unique combinations is 4371. The transformations are performed in square
surface units of 25 hectare.
