Just about every colonial New England town had one of these stone wall enclosures for containing livestock which had strayed from their owner’s land and were causing problems on other people’s property. The sheep, cattle, or other animals would be held in the pound until the owner could collect them and pay a fee. Many are still standing today, in varying states of repair, as historic reminders of these towns’ agricultural past. Hear about my efforts to find and “armchair map” these...| OpenStreetMap US All Posts

Despite heroic efforts by mapping communities on HOT’s Tasking Manager, many parts of the world are still unmapped. Often the data does not reflect the reality on the ground, particularly when it comes to OSM tags. Field-TM aims to help validating existing data with field verified information, and to add additional tags based on the situation on the ground. The goal is not to re-invent the wheel, but to leverage existing tech and coordinate the mapping amongst teams.| OpenStreetMap US All Posts
Train travel is often considered an environmentally-friendly alternative to other transit modes; however, the United States rail network is primarily served by diesel locomotives. Amtrak is currently rolling out newer locomotives that drastically reduce pollutant (nitrogen oxide, particulate matter) emissions. In this work, we use OSM rail shapefiles and speed limit attributes to investigate the impact of these upgraded locomotives on regional air quality in the United States.| OpenStreetMap US All Posts
My session will review my personal method for correcting TIGER roads. My process is idiosyncratic, but I find that though I do not follow the common method, it results in more accurate streets that are easier to comprehend than moving around the nodes on the street. I will be going over the pros and cons of this method. You may remember me from my talk “The Teenage Mapper” last year.| OpenStreetMap US All Posts
Stamen’s Map Stack was a platform created in 2013 for customizing existing basemaps by stacking, blending, and compositing raster tiles. This unique experience enabled quick, user-friendly map prototyping and endless creative expression by users on the web. A decade later, we are now retiring the service and spending some time visualizing the massive database of maps from the tool’s archives. This presentation will showcase some of the creativity enabled by Map Stack over its ten-year run.| OpenStreetMap US All Posts
MapSwipe is a mobile and web app that enables crowdsourced data collection for OpenStreetMap (OSM). Today, MapSwipe helps prioritize mapping efforts by identifying areas needing updates.

Mapping POIs accurately can be challenging at scale especially to include entrances. Often POIs in OSM aren’t aligned well to buildings or other features. Using smartphones and increasingly smart glasses it is possible for mappers to contribute their geographic pose (view) for a POI. These poses can be used to confirm or improve the location of POIs. To demonstrate the approach we’ll demo a mobile app that uses captured poses to improve the location of POI in a simple point and tap interf...| OpenStreetMap US All Posts
At SOTMUS: SLC, I told the story of how I became the owner of the oldest map store in New England. I discussed challenges of small business ownership, insights into how the public uses and perceives maps and how to support contemporary cartography in a marketplace that doesn’t know what maps are for. So much has happened since then and I want to provide the next chapter of my journey and share what I’ve learned after two years running this legacy company.| OpenStreetMap US All Posts
A simple-sounding challenge - running every street in a city - has a surprisingly complex definition. What counts as a street? What defines a city? OpenStreetMap’s data reflects the world’s messiness, from paths to freeways and boundary schemes for many different definitions of place. This talk explores how StreetFerret interpreted OSM data for pedestrian challenges, covering key tagging practices, boundary selection, and edge cases that challenge our understanding of how the world is org...| OpenStreetMap US All Posts
NYC streets have Honorary Street Names proposed by different local community leaders. This presentation centers on an area between Washington Heights and Inwood, Manhattan, and looks at the honorary names. It includes a feminist perspective, in line with the mappers’ collective Geochicas, to ask what’s in these names, why they should be part of OSM, and how the community can learn by visualizing the names. Finally, it reflects on the importance of extending the exercise to NYC in general.| OpenStreetMap US All Posts
Cycling infrastructure is essential for sustainable mobility, but its impact relies on accurate mapping in OSM. A pilot project in Bogotá, Medellín, and Villavicencio developed a methodology to map bike lanes using Mapillary and JOSM. This enhances cyclist routes, influences public policies, and fosters global collaboration. Documented on the OSM wiki, this replicable model is vital for creating more sustainable cities worldwide.| OpenStreetMap US All Posts

Food environments are viewed as the interface where individuals interact with the wider food system to procure and/or consume food. Data collection was undertaken based on GIS open-source technologies and collaborative mapping platform OSM using a systematic approach involving 3 phases: remote mapping, ground-truthing, and food-outlet survey. Spatial analyses were performed using QIS. Food outlets were spread out unevenly, with many of them (NCD-unhealthy) being closer to where students lived.| OpenStreetMap US All Posts
Overture Maps will have been around for 2-½ years in June. Its goals and mission are distinct from those of OSM but it is also a huge user and beneficiary of the data created by the OSM community. Come for a quick update on Overture Maps and to discuss something you may not know about Overture’s mission: The mission of Overture is not to make all spatial data open.| OpenStreetMap US All Posts
When preparing OSM data for use in a routing engine, graph topology is typically simplified to reduce network complexity. This compresses detailed ways into single edges, ideally between single-node intersections. However, complex intersections, such as those involving dual carriageways, can result in multiple nodes as well as small, intermediate edges. This talk shares some approaches that Mapbox uses to identify these subsystems and categorize possible maneuvers through them.| OpenStreetMap US All Posts
In this talk, we will explore how we can use Uber H3 indexes for both vector and raster analysis. We’ll discuss performance considerations, limitations, advantages, and how H3 tiles with raster cell values can be presented on maps. We’ll also cover Raster-to-H3 conversion strategies. Our toolkit will include rasterio, gdal,COG,PostgreSQL and their integration with H3 Python and h3ronpy libraries.
