FOSS4G 2024 Workshop

Overture Places + OSM: Deduplication and Verification
12-02, 16:00–18:00 (America/Belem), Room Guajará (C Block)

Overture Maps Foundation provides millions of points of interest (POIs) as open map data. This gives OpenStreetMap users a chance to improve the map using open source geospatial tools in Python, along with various open APIs, to compare and validate the data. This workshop will let users learn how to do it in a place on the map of their own choosing.


Overture Maps Foundation has released open data with various points of interest around the world, which are compatible with OpenStreetMap to be validated and added to the map. In this workshop, attendees will be able to fork and modify collaborative Python notebook in order to learn how to fetch and preview Overture Places, as well as apply filters, including using a bounding box or place polygon to get POIs in a specific neighborhood or city. They will then have the chance to request data from OpenStreetMap that is in the same area and explore methods for finding which POIs already exist in OSM, how they might be updated by adopting some of the attributes from Overture, and also finding which Overture POIs are eligible to be added to OSM, ans how to check which might have evidence that they really exist.

Attendees should have their own laptop, some basic Python knowledge, and an OpenStreetMap account to get started.
