This is the official page for OpenStreetMap U.S., a 501(c)(3) charity advocating and supporting OpenStreetMap in the United States. OpenStreetMap U.S. is a local chapter of the OpenStreetMap Foundation. Some of the United States OSM community resources are found on the OpenStreetMap U.S. website.


Main article: Foundation/Local Chapters/United States/History

OpenStreetMap U.S. was first proposed in 2009 and was incorporated on April 19, 2010, in Washington, D.C. The inaugural State of the Map U.S. conference took place in August 2010.

In September 2020, OpenStreetMap U.S. officially became a local chapter of the OpenStreetMap Foundation.


OpenStreetMap US strives to support the OpenStreetMap project in the United States through fostering awareness, ensuring broad availability of data, continuous quality improvement, and an active community.

Strategic Planning 2020

In 2020, OpenStreetMap US leadership came together to define a vision and strategic priorities for the organization that would complement our longstanding mission and provide guidance for the organization in the coming years. Below is the work that resulted from this year-long process.


As we work to manifest our mission, we envision a future where communities:

  • Have the knowledge, tools and support they need to use the power of OpenStreetMap to improve their world by mapping their world.
  • Are building digital literacy by accessing and contributing to OpenStreetMap for community benefit that contributes to a just and equitable society.
  • Inspire and support new leaders who carry forward and shape the future of OpenStreetMap as a trusted map and community.

Strategic Priorities

  • Maximize the impact and value of OpenStreetMap and our community.
  • Grow and sustain a thriving, connected OpenStreetMap US community with representation from and in all sectors.
  • Deepen educational and outreach efforts, with a focus on developing emerging leaders in ways that broaden equity and diversity in OpenStreetMap

Mapping for Impact

Mapping for Impact is a community partnership program led by OpenStreetMap US to support organizations in civic, environmental, and social sectors to solve targeted challenges and data gaps across the US using OpenStreetMap. Through Mapping for Impact, OpenStreetMap US works to:

  • Create data that is needed, where it’s needed. There are still unmapped places in the United States. By working with partnering organizations, we can focus efforts and energy on completing mapping projects with direct impact. And by focusing mapping efforts through tools such as MapRoulette and the Tasking Manager, we can help ensure that the data that is mapped meet the quality standards our community expects and our partners need.
  • Connect mappers with partners. OpenStreetMap US collaborates with local groups on how to support Mapping for Impact partners when and where geographies overlap. Where on-the-ground mapping and support are needed, we’ll need the support of local mapping groups, meetups, and individual mappers based in those areas.
  • Catalyze meaningful learning opportunities for students. In collaboration with TeachOSM, we’re developing lessons for educators to bring Mapping for Impact to the classroom. This will provide educators with service-based learning opportunities with direct impact here in the US. In the future,  we would love to create opportunities for university students and groups to further engage with these partners.

Mapping for Impact projects are also documented as Organized Editing Activities here. If you have any questions, concerns, or want to get involved with Mapping for Impact, please contact OSM US Program Director Jess Beutler at

KABOOM! Mapping for Playspace Equity in Philadelphia -

TM Project #252

Completed & Validated KABOOM! is working to achieve playspace equity by building quality playgrounds and playspaces in the United States where they're needed the most. You can help support this cause by mapping playgrounds in Philadelphia. Remotely mapping playgrounds will provide KABOOM! data on the number and size of playspaces in Philadelphia. After completing remote mapping, there will be opportunities for local mappers to support by filling in features with quality data on the ground. KABOOM! is the national nonprofit that works to end playspace inequity for good. We define playspace inequity as a lack of access to and a sense of belonging in quality playspaces due to the effects of systemic racism in communities across the country. Read more about the project and partnership here. #kaboom #mapping-for-impact #play-mapping #play-mapping channel on OSM US Slack Jess Beutler
Parks & Playspace Mapping in Colorado -

TM Project #284

TM Project #286

TM Project #287

Completed & Validated KABOOM! is working to achieve playspace equity by building quality playgrounds and playspaces in the United States where they're needed the most. You can help support this cause by mapping parks & playspaces in Colorado (Otero County, Rio Grande County, East Colfax Corridor). The Colorado Health Foundation is supporting KABOOM! to develop a strategic roadmap that details not only where playgrounds are, but their condition- enabling KABOOM!, community members, municipal leaders, and other philanthropic partners to accurately understand what playspace inequity looks like within these communities and address it through advocacy and data-guided investment. This playspace location data will become the basis of this roadmap. #mapping-for-impact

Rising Tide Effect Swimming Pools in NYC Active Mapping Rising Tide Effect is working to reduce social inequity and make our communities safer for children and parents by sharing the aquatic experience. You can help support this cause by mapping indoor and outdoor swimming facilities, and adding critical details where possible, in New York. Mapping these features will provide Rising Tide Effect with to help advocate for and improve youth access to swimming facilities. #mapping-for-impact #risingtideeffect-nyc #swimming-pools channel on OSM US Slack


Charter Projects

With the OSM US Charter program, OpenStreetMap US actively encourages the development of tools, programs and services that contribute to the growth and sustainability of the OpenStreetMap platform in the United States, and beyond. The Charter Project program provides a framework for long term stewardship and is loosely based on the fiscal sponsorship model for governance of non-profit organizations. Projects are given a home and the ability to fundraise through the OpenStreetMap US organization, a 501(c)(3) charity incorporated in Washington, DC. Applications are now open on a rolling basis. If you think your initiative may be a good fit to become an official OSM US Charter Project, we would love to learn more and get to know you! Check out the Guidelines document here.

Current charter projects:

Public Domain Map

Public Domain Map (PDM) is a project of OpenStreetMap US to develop a toolstack that will allow map contributors across the United States to edit, contribute to, and consume federal datasets via a collaborative user environment and OpenStreetMap tools; simultaneously improving government datasets and OpenStreetMap. Learn more on the official website of the project.

12 Months of OSM

12 Months of OpenStreetMap was inspired by the Project of the Month done by mappers in France, Switzerland and Germany. See the French wiki page Projet du mois and the German "Wochenaufgabe for examples. Setting a monthly theme provides the opportunity to learn and work together around a certain OpenStreetMap theme and can also used for targeted data improvement in under mapped places in the US. Learn more and check out the monthly themes here.

US Trails Stewardship Initiative

Main article: United States/Trail Access Project

OpenStreetMap US is leading efforts to support responsible mapping of trails on recreational land in the United States. Many navigation applications amalgamate this trail data from multiple sources and rely heavily on OpenStreetMap data. In late 2021 OSM US was approached by a land manager for support in improving the data. In response, OpenStreetMap US formed the Trails Working Group to help address how applications use OpenStreetMap data and the impacts on trail navigation. Bringing together a diversity of perspectives on trail mapping practices, trail safety, and protecting the environment, this group is working to address on-the-ground challenges, tagging schemes, authoritative data, and other topics related to mapping trails in OSM. The work of this group will be the basis for the implementation of a national campaign.

State of the Map US

The State of the Map US (SOTMUS) conference is the annual, regional conference for OpenStreetMap in the United States. Organized by OpenStreetMap US it has been held each year since 2010. Please note that regional SotMs like SOTMUS are organised exclusively by local teams, which run their own sponsorship programs and have separate budgets from the OpenStreetMap Foundation. Interested in hosting the next event? Learn more on the State of the Map US Planning page!

Mappy Hours

OpenStreetMap US hosts various remote "Mappy Hours" on different topics, usually every other week (once a month during summer months).

Geo-Ladies Meetups

OpenStreetMap US periodically hosts Geo-Ladies Night bringing together the women in the OpenStreetMap US community (and beyond), typically every 6 months. Expect to meet like-minded women from the OpenStreetMap community, connect, network, and converse on ways we can engage and empower more women through OSM. Event attendees will be limited to anyone who perceives themself as a woman. This women-only event is meant to create a safe space for participation by women and encourage diversity in OSM.
