add map plotting to xarray tools #41

Open annefou opened 3 years ago

annefou commented 3 years ago

I am planning to add an xarray tool to plot 2D xarrays on a geographical map.

Should I add it here in https://github.com/galaxyecology/tools-ecology/tree/master/tools/data_manipulation/xarray?

Hi Anne,

It seems to me of interest for ""our"" users, so I would say yes if you think this is ok !

Don't hesitate to say if you need help / review or feedback !

Cheers,

Yvan

Hi Anne. Is it possible to use the opportunity to work on this xarray_select tool to also systematically add an output dataset (maybe with log of the run written on it?) when using this tool as this tool is creating ""only" dataset collection and if there is an issue, user can't rerun and/or see what happen. A manner to face it is to automatically create a "flat dataset" as output of any run of this tool. Is it something you are agree with @annefou @bgruening ?

Thank you for your help and improvments !

Cheers,

Yvan

Yes, I am sure it can be done. I'll look at it ASAP.

We have been asked to add 1D plotting too (for time series; with proper dates on x-axis). Maybe something I can add too.

A few problems that have been raised with xarray map plotting tool:

Spaces in title and label do not work properly (for now you need to add for instance underscores...).
Meteo-france Weather Forecasts (AROME and ARPEGE) are now available on AWS and have been added as remote source. Format is grib2 and can be "ingested" by xarray tools if , engine='cfgrib' is added when opening the file.
xarray operations are very limited now. Simple operation for instance to convert from Kelvin to degrees Celcius should be offered.
