TERYT Map Plotter
A civic tech side project for turning TERYT-coded datasets into interactive maps of Poland.
Current status
Work in progress
I'm building this tool as a practical way to visualize Polish administrative data without forcing people to wrestle with shapefiles, GIS software, or fragile name matching.
The core idea is simple: bring a CSV with TERYT codes, pick a geographic level, and get a clean map you can explore, share, and export.
The source lives in the public GitHub repository, and I have now pulled it into this website repo so I can iterate on the product and presentation in one place.
What it already does
- Plots municipalities, counties, voivodeships, or the whole country from TERYT-based data.
- Supports built-in election datasets as well as uploaded CSV files.
- Offers shareable map views and PNG export for quick publishing.
- Keeps TERYT as the primary key, which makes the matching far more reliable than plain-text place names.
Why I care about it
I spend a lot of time around participatory budgeting, elections, and public datasets. A surprising amount of that work still gets blocked by one boring problem: the data is structured, but the map tooling is not. This project is my attempt to make that step much easier.
