How do I interpret the `isea3hcellcode` column in the occurrence cube results?

Miscellaneous

I’m trying to work with the occurrence cube output from GBIF in a Python project. I conceptually understand what an occurrence cube is, and what a hexagonal grid is. But when I try to read the ISEA3H cell code value using Python grid libraries, it doesn’t work because GBIF’s ISEA3H Java library is using a different variation of ISEA3H than the libraries I’m using. See this GitHub issue for more information about that:

So what I’m wondering is, how does GBIF expect users to interpret the ISEA3H column? Are there specific libraries we need to be using, and if so is that documented anywhere?

Alternatively, is there any opportunity to have GBIF’s occurrence cubes offer a simpler to understand grid like h3geo(dot)org?

Hello @coreyfarwell1912350

I have recently generated some shapefiles that address exactly this problem. I only generated up to resolution 9. So let me know if you want higher resolution since it might justify me spending more time on this project.

I am working with resolutions beyond 9, so this approach won’t work for me.
