Assessing Overture POI and Address Data: An Uber Perspective - Ran Li, Uber

Tuesday April 21, 2026 10:45 - 10:55 CEST

In this talk, we share Uber’s approach to evaluating Overture’s global POI and address datasets from a production maps perspective.

We will describe the goals and scope of our evaluation, including the international markets we focused on and the practical questions we aimed to answer as a downstream consumer of open geospatial data. The talk will outline how we assessed net-new coverage, data quality, and enrichment attributes, with an emphasis on understanding where open data provides incremental value and where gaps remain.

A key focus will be our evaluation methodology. We will walk through a multi-pronged approach that combines standalone sampling, comparative analysis against existing datasets, and trip-based coverage headroom to better approximate real-world user impact. Rather than relying solely on raw feature counts, this framework prioritizes where missing or incorrect data most affects actual usage.

Finally, we will share high-level findings and lessons learned from the evaluation, including observations on strengths, limitations, and areas where closer collaboration between data producers and consumers could improve outcomes.

From Global Maps To Local Meaning: Admin & Natural Features in Bing - Dami Onwah, Microsoft

Tuesday April 21, 2026 11:00 - 11:10 CEST

Global search products break down when they treat geography as a flat and uniform monolith. This session argues that administrative boundaries and natural features are not “background/secondary data”, but core product anchors that enable search products like Bing reason about Places the way users actually think (by country, region, colloquial area, or natural landmark). Drawing from Bing’s experience evolving its Admin & Natural Features layer, we show how a strong, consistent regional model can enable region specific queries, reduce market by market hacks, and unlock scalable relevance across the world. The talk reframes Admin & NF investment as a product decision, one that directly shapes user intent understanding, regional correctness, and long term search quality, rather than a purely infrastructural concern.

How Overture Helps GEM Perform Global Seismic Risk Analysis and How You Can Join In - Paul Henshaw & Marco Baiguera, Global Earthquake Model Foundation

Tuesday April 21, 2026 11:15 - 11:25 CEST

This presentation will outline how the Global Earthquake Model (GEM) Foundation is currently using Overture data to assess risk due to earthquakes and other natural hazards around the world, the limitations of currently available data, and potential opportunities for future improvements.

We will also present the outcomes of a workshop hosted by GEM earlier this year, bringing together organizations actively collecting and disseminating datasets regarding the built-up environment.

GEM has a number of open software tools, datasets and standards that can be used freely for risk analysis and we believe that there are a number of other organizations that might also be prepared to contribute their own tools, data and expertise.

We would like to use this presentation to invite other parties interested in working in Disaster Risk Reduction/Climate Adaption/Humanitarian Response and related fields to join us to explore ways in which we can collectively improve the Overture data ecosystem to reduce the barriers to risk analysis and risk reduction.

Connecting Data: Geospatial Insights Made Simple - Andy Bell, Precisely

Tuesday April 21, 2026 11:45 - 11:55 CEST

Increase awareness of the value proposition of connected geospatial data and how companies are exploiting that capability.
As geospatial data becomes increasingly critical for organisations seeking to make informed decisions, data enrichment, augmenting internal data with curated third-party data, is fast emerging as a key strategy.
In this presentation, we will show how using unique and persistent IDs, such as GERS, and the PreciselyID, makes it easier to integrate different geospatial datasets. This allows organisations to use and consume a wealth of trusted data for additional insight, including address and property data, points of interest, streets, demographics, boundaries, natural hazards, and more. We will also discuss the common challenges that organisations face when onboarding data and explain how connected data solutions solve these issues with our connected data solutions.
We will share examples of how leading companies use these capabilities to transform their operations and make geospatial insights accessible to everyone using a combination of Overture Places and Address GERs along with the extended attribution that can be connected to from Precisely.

Beyond the Dataset: Why Overture's Schema Matters - Bogdan Bebić, Microsoft

Tuesday April 21, 2026 15:40 - 16:00 CEST

In the AI era, data usability matters as much as data quality. At Bing Maps, we've learned that Overture's most lasting contribution to the Addresses theme may be its schema, not its rows. This talk shares lessons from our ongoing journey: escaping closed-ecosystem formats, adopting TomTom Orbis Maps address data, migrating our pipelines toward GeoParquet and Overture-aligned schemas, and starting conversations about format convergence. The work is not finished — but the direction is clear, and the early wins are already tangible.

Closing the Data Gap: Human-contributed Data in Overture in the Age of AI - Paul Uithol, Humanitarian OpenStreetMap Team

Tuesday April 21, 2026 16:00 - 16:20 CEST

In many areas of geospatial data, we believe human experience and interactions are what makes data usable. While AI/ML generated datasets are steadily improving in quality, these can’t capture numerous aspects of daily life.

It is, however, still difficult to access and tap into the many sources of local knowledge. To improve this, HOT is introducing the “Open Mapping Marketplace”, which provides a platform for organizations, including commercial companies, to procure open geospatial data that is locally sourced by mapping communities all over the world.

Data creation tasks can include imagery acquisition (mainly drone imagery for now), ground truthing of AI models, creating locally relevant and applicable training datasets in a sustainable and ethical way, and more traditional data collection and mapping activities.

This session will offer attendees a practical framework for engaging with open mapping communities in a way that drives data quality while ensuring long-term sustainability and mutual benefit.

From Multiple Sources to One Map: The Challenges of Data Integration - Ksenija Bulatovic, Microsoft

Tuesday April 21, 2026 16:20 - 16:40 CEST

Modern mapping systems depend on data coming from many different sources, including internal datasets, external providers, and community contributions. While each source may be valuable on its own, combining them into a single, consistent map is far from trivial. Differences in schemas, coverage, update cycles, and quality standards often lead to conflicts, duplication, and inconsistencies that must be resolved before the data can be reliably used.

This session explores the practical challenges of turning multiple heterogeneous datasets into one coherent map. Drawing from real world integration experiences, it highlights the types of issues that commonly arise when aligning data across sources and the trade offs involved in resolving them. The talk frames data integration not just as a technical task, but as a continuous process that directly impacts map quality, scalability, and the ability to maintain a trusted representation of the world.

Introducing the Places+Imagery Task Force and Vector Map Embedding Tiles - Sean Gorman, Zephr.xyz

Wednesday April 22, 2026 10:50 - 11:10 CEST

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

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

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.

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.

DuckDB + H3 for Fast Entity Conflation in the Browser - Max Lenormand, Fused

Wednesday April 22, 2026 15:00 - 15:20 CEST

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.

Graphlication: Making Overture Themes AI-Ready With a Provenance-Aware Spatial Knowledge Graph - Daniel Smith, Wherobots

Thursday April 23, 2026 09:05 - 09:25 CEST

Large language models are improving quickly, but place understanding still breaks in predictable ways: unclear building/POI containment, conflicting addresses, and duplicate or near-duplicate POIs. Graphlication turns Overture themes (Buildings, Places, Addresses, Transportation) into a provenance-aware spatial knowledge graph and retrieves small, evidence-bearing subgraphs for a specific query so an LLM can answer with traceable support. Rather than forcing early "golden record" merges, Graphlication keeps relationships (containment, adjacency, access, candidate conflation) explicit and audit-friendly. The talk shares a repeatable architecture and practical patterns that teams can apply to ship grounded place Q&A, streamline conflation review, and run systematic quality checks.
