#1627: Vector analysis tool that outputs corssing points of two dataset line or
line/boundary cross points
-------------------------+--------------------------------------------------
Reporter: marisn | Owner: grass-dev@…
Type: enhancement | Status: new
Priority: normal | Milestone: 7.0.0
Component: Vector | Version: unspecified
Keywords: | Platform: Unspecified
Cpu: Unspecified |
-------------------------+--------------------------------------------------
v.crosspoints module should take as an input two vector datasets and
output a new vector data set containing points only at line and/or
line/boundary crossing points.
Attribute data should be copied form the source datasets in to separate
layers. Module should provide an option to skip attribute data transfer
and just move CAT values.
Bonus feature (has to be discussed) - ability to store the distance from
the line start point to the crossing point.
Problems - a design decision needed - what to do if there are more than
single line crossing at the same point. Creating a geometry is easy, still
how should attribute data be handled in such case?
Currently it is possible to obtain two line dataset crossing points by
working around like it's described in this e-mail thread.
