Site specifications

coordinate system/grid data:
datum (e.g. WGS84):
WGS84
ecosystem type classification:
lakes (classification mainly according to WFD):
altitude typology:
 lowland: < 200 m
depth typology based on mean depth:
 < 3 m, 3 - 15 m
size typology based on surfcae area:
 0.5 to 1 km², 1 to 10 km², 10 to 100 km²
geology:
 calcareous, siliceous
other site classification parameters:
Geology is based on alcalinity. The threshold between calcarous and siliceous is 0.2 meq.
site coding:
site coding available:
yes
numerical
number of digits:
5
example:
45003
number of sites:
100 - 1000
exact number of sites:
276
comments:
Most Danish lakes are less than 0.5 km2, consequently the size typology based numbers are less than the total of 276 lakes.
