elements

If elem_tot = 1, there can be only one element in the Landscape Unit, whose number (id in rout_unit.ele) is specified in this column. If elem_tot >1, this column is followed by additional columns listing the elements included in the Landscape Unit, but those columns will not have a header. If there are several elements with consecutive numbers in a Landscape Unit, they can be listed by specifying the first one in one column and the last one with a hyphen in front of it in the next column.
