Connecting the Geospatial Dots with Raku

Geospatial programming often requires stitching together a variety of formats, interfaces, APIs, libraries, tools and languages. How can we fluidly download data from OpenStreetMap using the Overpass Query Language, run performant queries with GEOS, store and manipulate GeoJSON or WKT-formatted data with duckdb's spatial extention, and then visualize things with a javascript library like Leaflet or Deck.gl?

This talk explores Raku's expressive and powerful style as we mesh together all of these things, creating new modules along the way, and leapfrogging ahead of other implementations with some of Raku's unique features such as NativeCall for native libraries, Grammars for parsing, multiple modes of interacting with command line tooling, and plentiful concurrency models. Also let's see how we can rein in large language models so that we can apply them judiciously to our data and our code.
