Oh no, remote #GeoParquet is much less fun in #QGIS than I thought. These few polygons took ~50 Megabytes to fetch. I guess it is not enough to just use #GDAL defaults.

GIS file format comparison chart
Why #GeoParquet is the superior GIS file format? For one, file size. Here is a comparison between different formats using cadastral boundary data from the Estonian Land and Spatial Development Board. Note that GeoParquet is roughly 8× smaller than a #Shapefile.

I would add WebGL-based visualization libraries (e.g. #deckgl and #mapgl). They are not exactly super new but they're really centraly in how spatial data science has changed over the past 10-ish years.
ps. #GeoParquet, and #DuckDB + spatial ! would also be at the top of my list!

A discrete global grid (DGG) is a mosaic that covers the entire Earth’s surface. Mathematically it is a space partitioning.
What are the most exciting trends you’re seeing in spatial data science lately?
Some of mine:
- New file formats (e.g. #GeoParquet)
- Geospatial DBs (e.g. #DuckDB + spatial)
- Global discrete grids
What would you add?

Providers of geospatial data throughout the world: please move away from your dysfunctional APIs and download portals and embrace cloud optimized geospatial formats for both raster and vector. It will be less work for you and much better usability for us. #geoparquet #stac #cog

Why did #OvertureMaps choose #GeoParquet?
We asked our CTO Amy Rose how we’re breaking #geospatial data out of silos — from global scale to tool compatibility.

"It’s a true pleasure to share that in the time since my last couple of posts about the #QGIS plugin to download #GeoParquet data there is now a real community of contributors making awesome advances to the plugin."

The #GeoParquet initiative has always aimed to make geospatial data “boringly interoperable.” With Parquet and #Iceberg now supporting geometry types natively, GeoParquet is entering its next phase.

Pour afficher plus rapidement encore des couches cartographiques volumineuses avec le format #Geoparquet, pensez à les trier avec la fonction ST_Hilbert() de #DuckDB Spatial : cet article de @opencholmes.bsky.social l'explique de façon lumineuse.

www.shpshifter.com now supports GeoParquet files via @planetlabs.bsky.social github.com/planetlabs/gpq wasm library - but be careful - those parquet files can be huge - shown is Barbados buildings from source.coop

The #QGIS #GeoParquet Downloader plugin by Chris Holmes makes it really easy to download #opendata from #Overture and other sources. Watch my latest video to see how it works (and use it to create a wood-carved style map in :qgis: ). https://youtu.be/PRvadvTccEE

I'm curious, what's your experience with #geoparquet so far, #GISChat ?
Are you all in? Excited? Cautious? Disillusioned?
Why?
