Value too high or too low for decimal

[daveal81]

The Problem

What went wrong?
A DOD between two clipped DTM did not work (in QGIS the DTMs difference works)

Reproduction steps

1. I did this: import the survey and pre-existing DTMs
2. Then I did that...: Star to make DoD.

Paste the exception message you are getting from the app here. It really helps us. 

Anything else?

Here two original DTM that did not works

@daveal81 thanks for sharing the data. I was able to reproduce the problem in:

The problem is definitely associated with the 21 raster, and this is also the raster I point out in the video has poorly curated extents (see here for hints). I suspect that recreating that raster from the original data to be perfectly orthogonal with the 19 raster will fix the problem.

However, @philipbaileynar this is a new error we have never seen, so I am curious why. It is crashing out when creating the histogram (it seems to blow up), even though it is able to create the rawdod.tif. I tried seeing if I could make reference surfaces off of this or error models off of this and I was able to. I also looked at elevation ranges and there is nothing tell-tale in there. Anyhow, I'll be curious what you think.

Thank you Joe!,
I will try to fix what's going wrong with 21 raster

[daveal81]

Using a simple smooth filter (R=2=) of QGIS on 21 raster now it works. Thank you

@philipbaileynar and I have logged the issue still as a bug 🪲. Glad a workaround got you through.
