Floating-point MRF w/ LERC compression depth maps are correctly read, but the viewer is all black and measuring tools cannot be used about oriented-imagery

Can you share the sample with @abhiataero? I will look into it.

Hi Alex,

I looked into it. The MRF files with LERC compression that you provided have issues. They are not encoded properly. I can't even load MRF file in ArcGIS Pro.

If the file is corrupt, then why does the pixels array have correct values

[kushu493]

Pixels array also have wrong values. You can try to load the .lrc file with the sample app provided here. https://github.com/Esri/lerc
This is a lerc reader.

I see, thanks!

I know why the issue occurs now:
Under addDepthValues() in viewer.js:

                    var d = t.statistics[0].minValue,
                        u = t.statistics[0].maxValue,
                        g = 255 / (u - d);

u happens to be Infinity because I forgot to handle them, and g equals 0

Thanks Kushagra, the European dataset is all fixed now!
