Context: I want to cut *.xyz data for a river channel below the free surface.
I assume I want to use ArcGIS to generate a polyline based on my free surface data, and to clip out all topographic data that exceeds it. However, this isn't a method I've used before and it's been a long time since I've used ArcGIS. I've not found a method online either. Does anyone know where I could start, or what tools would be applicable?
Thanks in advance!
Thanks Xander,
I've snapped the points to the centre-line, however I'm still at the early stages of learning python (I only recently started a course) so in terms of processing the data I'd be on unsteady ground. What would I need to write to process the data?
Sorry for the delay. We're having the Colombian User Conference at this momento that has consumed a lot of my time.
If you could share a small part of you data (or some dummy data with the same schema) I could explain it a bit better and provide some example code.
Not to worry, that's fine. Would you rather me email you or message you on here (if that's possible - looking at the DM it looks like you can only attach links and pictures?)
If you attach it directly to this thread, you will enable other to collaborate too. I think that would be better.
