Image 1: A slide from Stefan Keller's presentation at State of the Map 2024 titled "Catching OSM Up with External Data with a Workflow and Tools for Conflation and Validation." The slide outlines the motivation for the talk, focusing on enhancing OpenStreetMap (OSM) through conflation and validation, showcasing interesting OSM activities, and introducing tools like OSM Conflator and DiffedPlaces. The slide includes an overview of the topics covered and a small portrait of Stefan Keller.

Image 2: A slide titled "Conflation in OSM: A general workflow," providing a step-by-step guide to the conflation process. Steps include discussing the import, mapping external data to OSM schema, validating data, calculating differences, and performing the import using tools like JOSM. The slide includes a portrait of Stefan Keller in the bottom right.

Image 3: A slide discussing "DiffedPlaces," a work-in-progress tool created as part of a master's thesis in data science by Claudio Bertozzi. The slide outlines the goals of DiffedPlaces, including implementing map matching algorithms with machine learning, calculating diffs for OSM data, and showcasing these diffs as GeoJSON on a public website. The slide includes a portrait of Stefan Keller.

Image 4: A slide titled "OSM Conflator: The data flow (and workflow)" depicting a flowchart illustrating the process of matching external data to OSM using the OSM Conflator tool. The diagram shows the steps involved, from data matching to validation and upload to OSM. The slide includes a small portrait of Stefan Keller.
