Topo to raster / Cliff function problem

fsbusschers — Fri, 30 Apr 2021 11:14:33 GMT

Dear members,

I'm using topo to raster to create a base of a geological surface in combination with faults. I thought this would be doable using the Cliff option in topo to raster.

But:

* If I run topo to raster using a sinlge faultline (see result_polyline2_single_fault.pdf) it works.

* If I run topo to raster using a shape with multiple faultlines (see result_polyline3_multple_fault.pdf) the faults are not taken into account (it just runs the ''normal topo to raster function).

The shapes are the same. Orientations are ok. Changing id's does not help, dissolving the multiple faults into one id also does not.

Is it possible anyway to run multiple cliffs at once?

I'm running topo to raster via pyhton 2.7 and arcmap 1.6 (see below).

Can anyone help me out?

Cheers, Freek, Geological Survey of the Netherlands !

p.s.: input datasets are gven in the attachment (file with the single fault, file with the multiple faults and the input borehole data from which I use the field "bottom")

Topo to Raster (3D Analyst)—ArcGIS Pro | Documentation

out_stream_cliff_error_feature

out_contour_error_feature

Did you try to run it with those optional parameters?

Could you test if Spline with Barriers gives you the desired result?

Dan, I (now 🙂 ) did (see below). About in the middle it says: "WINDOWED CLIFF SIZE 7 EXCEEDS MAXIMUM 35". You have any idea what that means? Cheers Freek!

Can't find anything in the help documentation, but since you said you had 7 cliffs but there are CLIFF HEIGHT ERRORS 6 my guess would be ...

Dear Jayanta, spline works like a rocket..... a very exact interpolator by the way. Not sure how it deviates from topo to raster but this seems very good... still I can't compare it with topo to raster... Cheers Freek
