Overture's Release Artifacts: STAC, GERS Registry, Changelogs, & More - Jennings Anderson, Meta
Wednesday April 22, 2026 10:30 - 10:50 CEST
Michelangelo
While Overture's regular release of more than 4B map features is the main character, each release also includes a number of other data artifacts that play significant supporting roles in making it easier to find, consume, and understand the larger Overture ecosystem.

This talk will cover each of the items in the GERS Ecosystem and show how the SpatioTemporal Asset Catalog (STAC) is a powerful, single entry point.

If you've ever wondered "How do I make sure I'm using the latest Overture data?" — this is for you!

Introducing the Places+Imagery Task Force and Vector Map Embedding Tiles - Sean Gorman, Zephr.xyz
Wednesday April 22, 2026 10:50 - 11:10 CEST
Michelangelo
At the beginning of 2026 Overture kicked off a new task force with a mission of improving places data using imagery. Initially this work has been focused on using street level imagery to improve the geolocation accuracy of POIs, and in the process confirming their existence. This session will share the early benchmark results from this work; testing the accuracy of POI placements to real world survey measurements. The conflation of street level imagery with places opens the door to several follow on opportunities 1) accurate conflation of buildings and places, 2) seeding the discovery of new/changed places and 3) generating AI native places data. For the last point we'll introduce the concept of vector map embedding tiles: a data format that augments Overture place and geometry layers with semantic and visual embeddings, entrance and signage primitives, and lightweight visual-language descriptions derived from street-level imagery. The goal is to demonstrate how Overture datasets can be transformed into agent-ready assets, small and simple enough to be utilized by on-device spatial memory that is suitable for modern AI assistants.

Deep Dive: Overture Place Categories Taxonomy - Ron Rice, Meta
Wednesday April 22, 2026 11:10 - 11:30 CEST
Michelangelo
Let's dig into the Overture Place Categories taxonomy, covering its history, evolution, and plans for ongoing governance. We'll explain how the taxonomy is organized, introduce the concept of "basic level categories", and describe some of the ways the taxonomy can be used.

The Overture Places theme is focused on points of interest (POI)--real-world entities such as hospitals, museums, parks, and schools. A core component of the Places theme is a taxonomy of about 2000 categories, organized into a hierarchy to facilitate exploration and discovery.

The taxonomy has been significantly updated in recent months to improve ease of use, provide greater interoperability between different systems and platforms, and optimize the accuracy and coverage of POI classifiers. In addition to overhauling the taxonomy, we introduced the notion of "basic level categories"--a subset of Place Categories used for generalization and industry alignment. There are a wide range of user-facing and backend use cases for the taxonomy, ranging from labeling and iconography in mapping interfaces to AI-assisted data ingestion and classification.

Building a Self-Healing Places Dataset With Signals - Greg Nieuwenhuis, Sparkgeo
Wednesday April 22, 2026 12:20 - 12:40 CEST
Michelangelo
Modern maps cannot be static. Places open, close, change sentiment, and shift relevance constantly. A single data point can be useful, but it is rarely trustworthy on its own. The real value emerges when signals are observed over time and in aggregate.

This session explores how historical and regular signals help create a self-healing Places dataset. Weekly signal updates allow the system to continually validate place confidence, improve accuracy, and prevent failures like navigating to a business that closed last week.

We will ground this discussion in the Overture Maps Foundation approach to Places and Signals, with a focus on the Contributor Club. Attendees will learn how the system aggregates signals from multiple providers to strengthen place confidence while protecting proprietary data.

This session is designed for members and contributors who want to understand how data fits into the pipeline, how signals compound in value, and what we can do to make contribution easier and more impactful.

Agents for Places Data Evaluation - Sajjad Anwar, Development Seed
Wednesday April 22, 2026 14:40 - 15:00 CEST
Michelangelo
I'd like to present on our ongoing project to build a toolkit that uses agents and LLMs to evaluate places data sources quickly. This process can prepare a QA report about potental places data to decide if they are worth considering for ingesting to Overture Places.

LLMs are somewhat good at these evaluation tasks. Combined with good instructions, evals, and deterministic tools the toolkit can scrape arbitrary data source web pages, transform the source data in different formats into Overture Places schema along with matching categories, and finally do several hueristics based QA and comparisons.

We'll walk through some examples and discuss the future of this toolkit as part of the Overture Places ecosystem.

DuckDB + H3 for Fast Entity Conflation in the Browser - Max Lenormand, Fused
Wednesday April 22, 2026 15:00 - 15:20 CEST
Michelangelo
DuckDB is rapidly becoming the FOSS tool of choice for fast, local analytics. Beyond being the onboarding tool for many to explore Overture data, DuckDB can also be used to build more powerful analytical tools. In this talk, we will discuss our experience at Fused using DuckDB and open source extensions like h3-duckdb to perform interactive cross-filtering and aggregation.

H3, an open source project originally developed by Uber, enables efficient entity conflation through fast spatial indexing for identity matching and deduplication, especially when combined with DuckDB for scalable local joins. This pairs naturally with Overture data and Overture’s Global Entity Reference System (GERS)—reducing reliance on brittle string matching and custom reconciliation pipelines.

In this talk, we describe the preprocessing and partitioning of Overture data, SQL analytics using DuckDB, and developing interactive and beautiful dashboards in the browser—highlighting how open, accessible entity IDs via Overture’s GERS and H3 make joining, sharing, and onboarding datasets dramatically easier.
