A lot of people fall into the trap of loading data as fast as possible. I say, take your time with it. Introducing, Pencil Map: pencil-map.netlify.app

one of the more awesome things you can do with DuckDB query geospatial data straight from github this is from the excellent Natural Earth Data, and contains the boundaries for all countries in the world

The GeoParquet 1.1 revision is out, adding support for spatial partitioning and native GeoArrow geometries Both have potential to massively speed up working with very large geospatial datasets. Next step is ensuring the ecosystem works with this version github.com/opengeospatial…

We recently sponsored Hack4Her, a female-focused student hackathon in the Netherlands. During the DuckDB Challenge of the event, teams built a community-driven app providing safe walking routes in Amsterdam using DuckDB and its geospatial library. networkinstitute.org/2024/06/18/hac…

Really exciting to see GeoPandas 1.0 released! Among a bunch of new features I'm most excited about native GeoArrow interoperability! Remember to pass use_arrow=True in geopandas.read_file for best performance! github.com/geopandas/geop…

Did you know you can reliably query 10X larger-than-RAM datasets with Python dataframes thanks to DuckDB? The threshold for "big" data is larger than ever. ibis-project.org/posts/1tbc

The initial goal of GeoParquet might have been modest. Its ultimate goal is a future where #geospatial data is integrated across the data landscape. Read Chris Holmes & Javier de la Torre's blog post to learn more about breaking the 'GIS' data silo. cloudnativegeo.org/blog/2024/07/e…
