Looks great! Another seemingly extremely similar project released in the last few days: https://github.com/raulcd/datanomy

Agreed, I find this to be a super productive environment, because you get all of vscode's IDE plus the niceties of Jupyter and IPython. I wrote a small vscode extension that builds…

This worked for me last month on a Mac M2: https://www.portingkit.com/game/278

https://visgl.github.io/react-map-gl/ is a react interface to MapLibre

I develop Lonboard [0], a Python library for plotting large geospatial data. If you have small data (~max 30,000 coordinates), leaflet-based Python libraries like folium and ipylea…

It can read from HTTP urls, but you'd need to manage signing the URLs yourself. On the writing side, it currently writes to an ArrayBuffer, which then you could upload to a server …

Arrow JS is just ArrayBuffers underneath. You do want to amortize some operations to avoid unnecessary conversions. I.e. Arrow JS stores strings as UTF-8, but native JS strings are…

That's why I'm working on the GeoParquet spec [0]! It gives you both compression-by-default and super fast reads and writes! So it's usually as small as gzipped CSV, if not smaller…

Your issue is that you're using the default (old) binding to GDAL, based on Fiona [0]. You need to use pyogrio [1], its vectorized counterpart, instead. Make sure you use `engine="…

Sorry, this is not true _at all_ for geospatial data. A quick benchmark [0] shows that saving to GeoPackage, FlatGeobuf, and GeoParquet are roughly 10x faster than saving to CSV. A…

Is this open? Is there a way to read more about it? Issues/pull requests?

nodejs-polars is node-specific and uses native FFI. polars can be compiled to Wasm but doesn't yet have a js API out of the box. As for the fastest way to serialize data to Pandas …

pmtiles are only the counterpart to the "overviews" part of COG. pmtiles doesn't give you analysis-ready data. For that, look to FlatGeobuf or GeoParquet (once it gets a spatial in…

10,000 coordinates are certainly not enough to see the difference, but at some scale this would be faster on the GPU. This is implemented in an nvidia geospatial library call cuspa…

I'm working on bringing GeoRust algorithms [0] (which include boolean operations) to the web via WebAssembly. See this blog post [1] for an intro. There's also separate work on bin…

I'm surprised this link works and doesn't redirect given https://macwright.com/2022/09/15/hacker-news.html
