Questions on quantitative indicators APLS and TOPO

[Sysilia]

I ran the project with my own 512*512 sized dataset and got pretty good visualization results, but when I was quantifying the results I referred to spacenet's evaluation metric to quantify my own results, and I got topo results where a large portion of the prec was 1.0 and a lot of results close to 1, which I thought was very unreasonable, but didn't I don't know what's wrong with it, do you need to adjust any parameter when you quantize it?
