Tools for OpenStreetMap and geospatial tasks
- osmx-rs: a Rust port of OSMExpress, a fast database file format for OpenStreetMap
- sourdough: a free vector tile schema for OpenStreetMap data, with a Planetiler reference implementation (demo)
- duckdb-osmium: a DuckDB extension for reading OpenStreetMap PBF files using libosmium
- roadzilla: generates road layers for MapLibre stylesheets to achieve sophisticated road cartography
- osm-cli: fetch data or subscribe to edits from OpenStreetMap
- overpass-cli: use the Overpass query language to fetch OpenStreetMap data
- shapely-cli: transform GeoJSON using Python one-liners with the help of the shapely library
- usfs-to-osm and nps-to-osm: scripts to convert official USFS and NPS datasets to an OSM-compatible schema
- parks.osm.fyi: website which lists parks, nature reserves, and protected area boundaries in OSM
General-purpose CLI tools
- xpath-cli: evaluate XPath expressions on XML documents using libxml2
- grex: transforms XML into a flat, line-oriented form; like gron but for XML instead of JSON
- loc: count lines of code in files (reads filenames from stdin)
- ngrams: computes the frequency of sequences of characters (n-grams) in a text file
- barchart: prints barcharts in the terminal, helpful for commands that output lists of numbers
- uu: show the Unicode code points, names, categories, etc of each character in a given text
- gh-log:
a
logcommand for theghCLI to remind you what you did last week
Web development things
- postcss-minify: a CSS minifier in 50 lines of code (it's surprisingly effective)
- remark-sectionize: wrap headings and the content that follows them in
<section>elements
Miscellaneous stuff
- I made some explorables with d3 and Observable, like a satellite ground track visualizer and a map tile visibility demo
- I wrote about how to use Hobby's algorithm to make nice looking Bézier splines
