Just released an update to my point-in-polygon library. Now smaller and faster, but most importantly more accurate with robust floating point maths thanks to the excellent robust-predicates library by @agafonkin.com github.com/rowanwins/po...

Published a long overdue update to my js sweepline-intersections library to make use of the excellent robust-predicates library for improved intersection detection. github.com/rowanwins/sw... This library is downloaded >100k times a week thanks to TurfJS which is a tad scary when doing a release 😅

For anyone interested in displaying a flatgeobuf file efficiently on a maplibre-gl / mapbox-gl map I've created a little library that helps make tiled requests to your flatgeobuf datasource, this is particularly handy if your datasource is very large. github.com/rowanwins/ma...

Hey #geospatial brains-trust: what cloud-native #GIS data format should I use for my data? I have a largish point dataset (27 million points, 36 columns) that I want to put on AWS S3 for remote access. Ideally, I'd love users to be able to load data for a small AOI without downloading everything!
