which vertical datum do we use in OBIS?

[Ayush Anand]

Overview

Some endpoints in OBIS ask for an additional z coordinate over (x,y) for a location. I hope z means vertical datum here. So, which particular datum do we follow - WGS 1984 or NAD 1983?

One of the endpoints that ask for (x, y, z) is occurrences/tile/{x}/{y}/{z}

A sample query:

I'm fairly certain it's WGS 1984

@albenson-usgs is this true?

[Abby Benson]

Yes WGS84 is what is required for OBIS and GBIF.
