I'm looking for a tool that would be able to automatically snap features closer than a given distance. Is there such a tool/plugin for QGIS/GRASS/OpenJump? Would it be possible to achieve that with PostGIS?
I have a river network where some of tributaries don't touch the river they flow in and I need to get them snapped.
Answer
In GRASS GIS, you can use v.edit for this. There is " snap: Snap vector features in given threshold" along with the possibility to define a box or polygon to spatially constrain the snapping to a certain area in the map as well as "where" to constrain with attribute selection.
