Missing attributes on ICGEM datasets

Description of the problem

We currently have three sample datasets that have been downloaded from the ICGEM Calculation Service:

• Earth Topography
• Earth Gravity
• Earth Geoid

Each dataset can be fetched through its own function. Every one of these functions claims to have more details regarding the generation of the grid under the attrs attribute of the Dataset. The problem is neither of the returned Datasets have non empty attrs.

Would be nice to correct this and include the attributes related to the grid generation. I think these grids where generated by @leouieda, so maybe he has more idea of what information should be included on the attrs.

Just by naming some possible attributes that appear on the ICGEM Calculation Service:

• Reference ellipsoid
• Height above the ellipsoid
• Grid step
• Model used (for gravity and geoid)
• Tide system
• Zero degree term (yes/no)
• Gaussian filter and filter length
• Low-pass filtering
  • Start gentle cut
  • Maximum degree

@nshea3 have you made any advances on this?

I’m thinking we might want to solve this (along with #124) before completely moving the datasets to Rockhound, which won’t live inside its repository, but on a Zenodo archive (cc @mtb-za).

Please, @nshea3 don’t feel pushed to work on it. Just do it if you have the time. Otherwise, please let me know.

Hi all! This one slipped my mind during the spring. I have not started on it yet but I have plenty of time to work on it this week. I’ll let you know how I progress.
