Earth Science, open-source software development (https://xarray.dev/, https://fastscape.org/, https://github.com/geigr, Spherely, etc.) and music creation. https://benbovy.github.io/
Finally released Spherely 0.1.0! If you are using Shapely with latitude / longitude data, you might want to try Spherely instead. It provides similar API but relies on spherical geometry (via S2Geometry). 🧵
I started using #pixi for some projects that I maintain and also through `pixi global` (it might replace homebrew at some point for me). I must say it's a breeze! Great work @prefix.dev ! github.com/fastscape-le...
Setup pixi by benbovy · Pull Request #170 · fastscape-lem/fastscapelib
add tasks (cpp, python, dev, doc) update doc instruction (install, build and configuration, contributor guide) test pixi in CI

This blog post by @kylebarron.dev nicely fills a (frustrating, in my experience) gap between high-level descriptions vs. raw code implementations when trying to have a deep understanding on how spatial indexes work!
Kyle Barron@kylebarron.dev · 2y agoSpatial indexes, and RTrees specifically, are at the core of geospatial software. But ever wondered how an RTree is actually implemented? In this post we’ll dive into the implementation of Flatbush, an elegant, blazing-fast, memory-efficient RTree. kylebarron.dev/literate-fla...

📣 Hiring! I am looking for PhD/postdoc candidates to work on foundation models for science at @ULiege, with a special focus on weather and climate systems. 🌏 Three positions are open around deep learning, physics-informed FMs and inverse problems with FMs.

💯 Very much like relying more and more on GPS and has slowly eroded our ability to navigate ourselves...

New #gischat post! This one following up as a practical Ibis/ @duckdb.org-powered exploration into a few of the spatial partitioning methods suggested in a recent GeoParquet discussion. Let me know what I missed! dewey.dunnington.ca/post/2024/pa...
Partitioning strategies for bigger-than-memory spatial data | Dewey Dunnington
There’s a great discussion going on in the GeoParquet repo about how exactly to split up GeoParquet datasets for optimal querying. This post is my adventure giving the partition strategies a shot for ...

How do deformation, erosion, and precipitation interact during orogenic growth? ⚒️ Find out in this new study led by Xiaoping Yuan where we used a 3-code coupling between #ASPECT, #FASTSCAPE, and #LFPM. Article here: www.nature.com/articles/s41... 🧪 @natureportfolio.bsky.social @gfz.bsky.social
I might be wrong but Blender seems still heavily underused for scientific visualization. It has so much potential, and the example below illustrates it well! Blender learning curve is pretty steep, though. That's the cost for such a powerful and flexible 3D modelling / rendering software I guess.
Aafke Gros@aafkegros.bsky.social · 2y agoMicroscopy Nodes 2.0 is out! This includes a new channel interface and OME-Zarr support! 🔬🎉 www.youtube.com/watch?v=ybQc...
I enjoyed watching this video! The title of the video makes me realize I loved "playing" at Flight Simulator not so much I dreamed being a pilot as I love exploring maps.
Max Lenormand@maxlenormand.bsky.social · 2y agoIn a few days Flight Simulator 2024 is out You might think it's just another video game In reality it's the latest in a 40y+ series pushing the boundaries of graphics & mapping Let me tell you the Story of how Microsoft accidentally made the best map -> youtu.be/JIQxJWoKcPs
Running landscape evolution models (Fastscape) on a global (HEALPix) grid. It is pretty fast: the simulation below took ~25s on a old(ish) macbook pro intel (~800k grid nodes, 100 time steps, uplift + single flow routing + sink resolving + stream power law).
