Benoît Bovy @benbovy.github.io · 18/02/2025The development was supported by @numfocus.bsky.social (small development grant for the #GeoPandas project). A lot of the credit goes to Joris Van den Bossche and @paleolimbot.bsky.social (through S2Geography). Also many thanks to the new contributors! github.com/benbovy/sphe...github.comGitHub - benbovy/spherely: Manipulation and analysis of geometric objects on the sphere.Manipulation and analysis of geometric objects on the sphere. - benbovy/spherely 131
Benoît Bovy @benbovy.github.io · 18/02/2025It still misses a lot of features but already provides all the basic functionality: IO functions (WKT, WKB, GeoArrow), most predicates / measurement / overlay operations as well as a few constructive operations... All exposed as vectorized functions. spherely.readthedocs.iospherely.readthedocs.ioSpherely Documentation 100
Benoît Bovy @benbovy.github.io · 18/02/2025Finally 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). 🧵 152
Benoît Bovy @benbovy.github.io · 17/01/2025I also did `pixi global install micromamba`, because why not? I still find the "conda workflow" (explicit environments + manual activation) relevant for some of my uses cases. 000

Benoît Bovy @benbovy.github.io · 09/01/2025It leverages Xarray indexes so the CRS information is propagated seamlessly through operations and is used for auto-alignment of Xarray objects. It also provides some mechanisms to integrate it with other Xarray extensions (TBD). 2/2 030

Benoît Bovy @benbovy.github.io · 08/01/2025This 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! 030
Reposted by Benoît BovyKyle Barron @kylebarron.dev · 08/01/2025Spatial indexes, and RTrees specifically, are at the core of geospatial software. But ever wondered how an RTree is actually implemented?

Benoît Bovy @benbovy.github.io · 13/12/2024💯 Very much like relying more and more on GPS and has slowly eroded our ability to navigate ourselves... 000
Benoît Bovy @benbovy.github.io · 11/12/2024Nice! We should provide similar s2 cell utility functions in Spherely as well to allow such things! 🙂 042

Benoît Bovy @benbovy.github.io · 28/11/2024I 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. 140

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). 2142
