Interested to learn how I converted Swedish street network from Trafikverket.se to R5R compatible format (that is, osm.pbf)? See my other draft R package nvdb2osmr github.com/e-kotov/nvdb... based on nvdb2osm Python scripts github.com/NKAmapper/nv... .

#r5rgui v0.2 for r5r (@urbandemog.bsky.social) New: - compare routes and transport modes - compare networks! (e.g. OSM vs official streets Trafikverket.se) - query speed - custom basemaps (via `mapgl` @kylewalker.bsky.social ) Still in one line of code! www.ekotov.pro/r5rgui/ #rstats #gischat

#rstats osrm.backend 0.2 is out. I fixed a bug that might have caused lockup if you tried to calculate too large origin-destination matrices. REST API limits still apply. Get it from CRAN! osrm.backend::osrm_start("data_folder") 📘 Quick Start: www.ekotov.pro/osrm.backend... #OSRM #routing #gischat

DuckDB now supports reading from and writing to the Vortex file format! The DuckDB Labs and Spiral teams have worked together to make Vortex available as a core extension in DuckDB. We gave it a test drive, and it performed very well. Read the full article to learn more lnkd.in/eZfGzPiZ

I've been posting about PMTiles for geospatial visualization for good reason. However - you can push mapgl quite a ways without tiles! In this post, I cover how to map all 85,000+ Census tracts in the US without pre-tiling, along with performance tips. walker-data.com/post...

Having used VScode and Positron for the past year instead of RStudio, I wanted some familiar shortcuts for Zotero to quickly toggle side panels. Unfortunately, Zotero does not allows this easily, but there are hacks. I stored brief instructions here github.com/e-kotov/zote... . Setup in 3 minutes.

From a Q2 (according to @elsevierconnect.bsky.social ) journal asking for a review. They are not even trying. According to them, I have an "expertise in areas related to linguistics (if any)" [I love this "if any"!] , makes me "an ideal candidate to review the manuscript".

Speaking of tabulapdf, could everyone please have a look at the personal message from the dev pacha.dev/blog/2025/08... he needs some help

@htenkanen.bsky.social @waeiski.bsky.social , hi, have you had any experience with these Finland-wide GTFS files and #r5r or #r5py? www.fintraffic.fi/fi/digitaali... I am having issues with making those work, routing just fails. I suspect there must be some cleaning done on those GTFS files.

#Accessibility modelers using #r5r #rstats, check this GUI for playing around with R5 network. If many people find it useful, I would get signal if I should invest any more free time into it. github.com/e-kotov/r5rgui (uses #mapgl by @kylewalker.bsky.social and #r5r by @urbandemog.bsky.social et al)
