I really took a deep dive into #datashader with this map: Locals & Tourists in Germany, as derived from 67 Million Geo-Social Media Posts (2007-2022) in Germany. The data includes public shared posts from Instagram, Flickr, Twitter and […]
#python #bokeh is a very cool #datavis tool.
It interfaces neatly with #xarray and allows for interactive visualisations of >10k particles.
Throwback to last month in Bologna! 🌊
EGI, CMCC, UniBo, and EDITO hosted the Cloud Native Ocean Data Analysis School, empowering 40 scientists with #Pangeo, #Xarray, and cloud tools for marine data.

why in #xarray a simple operation such as querying what are the different group's name is stored in a netcdf involves using backend calls? the same operation so much easier if using the #netCDF4 module.
I wasted 2 hours figuring out that group name identification is easier using netCDF4. #python
finally got some legs on this #GDAL #xarray backend:
github.com/mdsumner/gdx
in combination with the upcoming 'gdal mdim mosaic' this should be pretty fun
if you wonder about coordinates in arrays and netcdf and Zarr and #xarray check out this awesome video and gallery, to see where xarray is going

excellent presentation by @deepakcherian.bsky.social of #earthmover
What if all your lab and ML data lived in one place? Index chaos is optional—xarray keeps everything aligned. I show how this cuts errors and makes analysis smoother. Would this help your workflow? Repost or comment! buff.ly/6QXFDY4 #xarray #datamanagement
A top alternative discussed is Xarray. It adds named dimensions to arrays, greatly simplifying broadcasting & alignment compared to raw NumPy operations. Makes working with complex datasets much cleaner. #Xarray 2/6

Anyone familiar with cfgrib?

This code all worked fine for years, until I updated #metpy last week. Updating the dependencies broke... everything, basically. Very annoying.

I am really looking forward to a time when scientific data analysis is less of a constant fuckaround and fight with technical bullshit. I'd *really* like

Hey folks, I just released xagg==0.3.3, with a new backend that can result in a massive speedup for huge datasets.
Use
`with xa.set_options(impl='numba'):`
and let me know your results!
(I just got 2 orders of magnitude speedup on `xa.aggregate()` on a test )

Released xproj: a small, generic (and experimental) #xarray extension to manage the coordinate reference system(s) of geospatial data cubes.
github.com/benbovy/xproj
1/2
It takes @xarray.bsky.social and #geopandas inputs, and outputs back to #xarray, #pandas, csv, and more (keeping polygon metadata intact!), so it can plug into many existing workflows.
There are some pretty substantial performance improvements in the pipeline as well, so stay tuned.
Computer room with participants working on code exercises in xarray.
Second day of UGent doctoral schools "Python for GIS and Geoscience" together with @jorisvandenbossche.bsky.social. Today focus on raster data #xarray. Great to see the wide variety of backgrounds, ranging from climate science to criminology.
Exporting an #xarray array containing an irregular mesh to geotiff is still something that is “not a breeze”
Justus made a great intro on using #DGGS through #xarray #xdggs at the #Pangeo showcase talk. Xdggs is now in a stage where you can use it fairly robustly with #HEALPIX and #H3. Other integrations like for #DGGRID are developed as separate plugins.
