URock analyzer problem

[biglimp]

I just removed my java and installer openjdk version 21 instead as my Uni does not allow us to use commercial java. I was able to run URock prepare and Urock v2023a but the analyzer fails. I worked before. I use the new line with only two vertices.

Yes, you used stream plotting which does not work with the way I interpolate the data. Extra code is needed to make it work in all situations.

[j3r3m1]

I remove the stream option for now

By the way what are the resolution of you voxels ? Are they same height than width ?

[biglimp]

I think so but maybe not. I resample to 1 meter i horisontal but that maybe is only for the geotif?

You are correct, it works using arrows.

The issue is that it is a little hard to see...

Yes normally it is fine with the resolution it should work. I can remove this functionnality temporarily what do you think ?

[biglimp]

Sure, just disable and than fix it when you got time...

@j3r3m1 , is really an issue any longer or can we close?
