[GRASS-user] Help with v.select with GRASS GIS 7.2

Hi all!

I’m trying to use v.select to find the intersection/crossings of a pipeline path across a stream network…

v.select -r --overwrite ainput=pipeline_streams@teaiii atype=line binput=mvp_path@teaiii btype=line output=mvp_stream_crossings operator=crosses

I’ve tried several options of crosses, intersects, overlap, etc., with and without ‘reverse’, each time getting:

Output:

Processing features…
ERROR: IllegalArgumentException: point array must contain 0 or >1 elements

Any thoughts with this??

Thank you,

Tom

Could you create an example with the NC sample dataset?
