Hello Jody,
thank you for your reply!
I tried the shapefile in uDig and it was displayed without errors.
The shapefile consists of approx. 3 million linestrings only with a start-
and endnode.(It is an ESRI TINfile saved as shapefile)And I need the
coordinates of each start- and endnode of each line.
