[Gsoc-orga] A project to fix the Polish government data import pipeline

Wed Apr 2 14:00:02 UTC 2025

Hi everyone,
Indeed, Cristoffs and I discussed adapting the tool to the import of the Spanish Cadastre (https://wiki.openstreetmap.org/wiki/Spanish_Cadastre/Buildings_import). The import has been accepted for years, but due to a lack of proper tooling, the import has been embarrassingly slow and painful. An improved toolchain will greatly benefit the import process, ultimately adding building and address data in most of Spain (The Cadastre covers 46 out of the 50 Spanish provinces, and the autonomous cities. The other 4 provinces have each a different Cadastre because of historical reasons.).

Best,
Héctor

The goal of this project is to create a new tool that will help process data from Polish Head Office of Geodesy and Cartography, identify missing addresses/buildings and make it easier to add them to OSM using JOSM. This is in line with GSoC's goal of writing software. The actual data import will not be part of the GSoC project itself, but rather the development of a tool for processing and preparing data.
> > * Reuse and Sustainability: We fully agree that open-source projects should be reusable and sustainable. The current platform allows users to download missing addresses/buildings in a structured .osm format, ensuring it can be reused for similar projects in the future. We are considering starting fresh to ensure a more stable and maintainable platform.
