Re: [GRASS-user] Cut a floodplain polygon with 1meter wide polygons perpendicular to its river channel
Just one quick thing, do you know if dleft and dright can snap to the polygon edge? Thanks On Domh 14 DFómh 2018 at 23:30, Shane Carey wrote: > Super, thanks Johannes.

Re: [GRASS-user] Cut a floodplain polygon with 1meter wide polygons perpendicular to its river channel
Shane, have a look at the GRASS v.transect add-on: https://grass.osgeo.org/grass74/manuals/addons/v.transects.html The manual says: "Creates transect lines or quadrilateral areas at regular intervals perpendicular to a polyline."

[GRASS-user] Cut a floodplain polygon with 1meter wide polygons perpendicular to its river channel
Hi, I need to cut a floodplain polygon into one meter strips which are perpendicular to the river. This needs to be an automated process. Just wondering has anyone ever done this or similar in Grass GIS through python or a bash script? The link attached shows two slides. Stage one is the first slide and slide two is what I hope to end up with. https://docs.google.com/presentation/d/1x7IQ3BJlLLSb6R2atxIIiaeWzyCqCZQ3uWaGPZyo6ds/edit?usp=sharing Any help would be appreciated.
