openocc_data

[RuanBispo]

Hi could you explain better the openocc_v2 data? what is the "instances" field? Are there 17 classes inside of the semantics? could you provide the labels?
For example
0 = car
1 = vegetation
...
16 = empty

I see that in you code you are using the visible mask, but I was not able to find it too.

Thank you!
