There are many flavors of #OSM, from the classic style on openstreetmap.org to Americana, OpenTrailMap, OpenCycleMap, and more. Some people create physical maps too, using QGIS or other GIS apps. But what about physical maps drawn with plotting machines where each layer requires swapping a pen and hoping everything stays aligned? This #SOTMUS2026 talk shares stories from experience making maps with these drawing machines using favorite OSM tags.

This #SOTMUS2026 presentation offers a first look at the new #MapRoulette interface. The redesign aims to give users a fresh interface with targeted improvements, without breaking the "flow" that has worked for mappers for 13 years. Whether you are new to MapRoulette or a veteran user, try out the public beta to improve the #map, create tasks for the community to solve, and give feedback.

#OSM users want to know whether the map reflects reality at their location and for their points of interest (POIs). This #SOTMUS2026 talk covers a statistical model using changesets to estimate OSM's data fidelity for POIs, including shops, amenities, leisure, and healthcare. It explores the model and demonstrates its uses for understanding change over time in a city, prioritizing reviews, and conflating OSM #POIs with other #open-source #datasets like Overture Maps.

#OpenHistoricalMap is more than a map. As an #opendata project, it aims to help people discover and understand the wealth of information that mappers have contributed, whether or not it fits on the main rendered map. In this #SOTMUS2026 talk, learn about OHM's analysis tools, what you can do with them, and the shortcomings the project wants to address with community help.

I wrote a recap of the #SOTMUS2026 conference on the @stamen blog:
-
This #SOTMUS2026 presentation shows how #OpenSidewalks (OSW) data has been published as reference layers and surfaced directly inside the Rapid editor, so mappers can use it today as part of their workflow while mapping pedestrian infrastructure in #OSM.
-
On June 29, 2025, the Metrobus network in the Washington, DC area was radically altered overnight. Every route number changed, bus stops closed, and some routes became entirely different from the day before. This #SOTMUS2026 session explores how a few mappers quickly incorporated new data into OSM and inspired others to update bus networks in the surrounding area.

GrabMaps' KartaDashCam transforms everyday ride-hailing trips in Southeast Asia into a passive mapping fleet. This #SOTMUS2026 talk shares the architecture, results from thousands of deployed units, and the technical and operational challenges of scaling edge-first map-making.
-
In 2025, the OSM US & Mapillary Camera Grant Program distributed 40 cameras to the #OSM US community. This #SOTMUS2026 talk describes the grant program's impact from the perspective of one local mapper. It also discusses scaling street-level imagery collection in the US on Panoramax, a federated, free, and open-source platform.
-
This #SOTMUS2026 presentation covers using official government datasets from the Bureau of Land Management, the National Park Service, and the U.S. Forest Service, and processing the data to update OSM with useful information, such as trail names or road reference numbers.
-
OSM has been the basis for several transportation network datasets, such as SharedStreets, OSMnx, and, most recently, Overture. This #SOTMUS2026 presentation explores how road network owners and transportation specialists can benefit from well-structured networks, making OSM the true worldwide datum for transportation.

#OSM data quality evaluations typically focus on measuring the accuracy and usability of the data. But how do diverse contributors collectively decide what "good quality" data actually looks like? This #SOTMUS2026 session shares a study showing (1) how data quality is shaped, and (2) how navigating data quality conventions helps contributors build expertise and belonging within the community.

Emma Farahay explores the history of Sanborn Fire Insurance Maps in Sandusky, Ohio, in this #SOTMUS2026 presentation. How might these maps be used by local agencies versus local history buffs and mapping enthusiasts? Consider the possibilities of analyzing the minute details preserved in the Sanborn Fire Insurance Maps.

The Eastern Turnpike operated between the areas of Albany, NY, and Williamstown, MA, from 1799 into the late 19th century. A private toll road, it was typical of the period, and there were many such roads in upstate NY. Sources discussed in this #SOTMUS2026 talk include NYS lidar data, highway department records, old topo maps, and NYS State Archive records.

#AI models are increasingly integrating #openmapdata into their corpus. Should the community leave AI labs to their own devices or help mediate this interaction? This #SOTMUS2026 talk proposes vector map embedding tiles: a data format that augments open map data with semantic and visual embeddings, as well as lightweight visual-language descriptions derived from imagery.
-
When HIFLD Open was taken offline in 2025, a community effort launched to restore its 400+ critical data layers. This #SOTMUS2026 talk explores how HIFLD was prepared for this agent-driven future by minimizing entropy, formalizing interfaces, and leveraging #OSM as a foundation for durable, machine-ready infrastructure data.
