Sorry for asking a question which I found in similar ways already here, but I am trying this for days and just got no result:
How do I calculate the area between certain contour lines (e.g. 0-800, 800-1400, 1400-2100...) from a given shape file. What I need is the area of the the certain elevational levels.

- shape file is from vogis-data download (via FTP vogis.cvn.at - Gelaendemodell - Hoehenschichten - Vlbg), vector polylines, altitude is ranging from 200 - 3300 m, but not equidistances
- lines to polygone seems not to work (too complex/large data?)
- fieldcalculator $area did not (only lines?)
- there is no DEM in raster format
