October 6, 2022: DGGS and their potential impact in Geoscience and Geospatial communities

Thank you for joining the Pangeo online Show & Tell 🎬 💬 !

We're delighted to have you here 🎉

What? Pangeo is a community-centric initiative that promotes open, reproducible, and scalable geoscience.

Show and Tell are online calls to gather feedback informally, but more importantly, it's a monthly celebration of what the Pangeo community has accomplished.

S&T are organised by members of Pangeo Europe continental meetings (see notes of previous meetings here).

When? 8 October 2022, 14:00 - 15:00 CEST (see in your time zone)

Next call: TBC, November 2022

• Q: What library should we use to "interpolate/convert" from geotiff to DGGS? I mean for physical quantities.

  A: Depends.

• Q: Can the ID of hexagons be made to be intuitive (i.e. to include notions of lat and lon for for instance)?

  A: No, it's systematic.

• Tips:

  • check the Binder and the Presi

• Q: plotting is based on matplotlib/hvplot like in python? how is it different from python enviroment?

  A: In this example, the backend is matplotlib. It can be something else.

• Q: when plotting plot(europe.time.values,europe[Variable="air_temperature_2m", lat=50, lon=11].data) do we need to provide the exact lat/lon or the nearest? point is selected?

• Q: Can users set the strategy for imputing missing values?
  A: yes, it needs to be passed through the function

• Q: Can you transform YAXArray objects to sort of xarray.Dataset?
  A: There is DataSets object

• Tips: cutting connection to rmprocs(workers())
  starting process : addprocs, it can be for on the same node as threads, it can be process outside the node that main julila process is running.

• Tips: docstring is with '?' , for example ?addprocs

• Tips: 'a .+ b ' is for applying the '+' operation for all the element of 'a' . For example if you have a=rand(3,3) b=rand(3,3), 'a .* b ' and 'a * b' do not have same answer.
