Humanitarian OSM Team
From the early days of OpenStreetMap it was anticipated that open, free map data would be a tremendous benefit for humanitarian aid and economic development. The idea was proven during the Haiti earthquake in 2010. HOT was incorporated in the immediate aftermath, August 2010, as a U.S. nonprofit under the name HUMANITARIAN OPENSTREETMAP TEAM UNITED STATES INC and then became a registered 501(c)3 charitable organization in 2013. Anyone is welcome to contribute to the HOT mission via our Tasking Manager. All you need is an OpenStreetMap Username.
HOT Mission and Objectives

- To be the connecting point between humanitarian actors and open mapping communities
- To provide remote data creation during crises
- To collect and organize existing data sources
- To support deployments to the field
- To be a distribution point for free data
- To develop open knowledge and tools
Advocacy, Training and Outreach
- mapping parties
- Communicating and meeting with humanitarian actors and United Nations technical communities
- HOT Toolbox
Thinking and Design
- To promote crowd-sourcing and simple web standards for data sharing
- To develop technical improvements to OSM and OSGeo in response to field requirements (off-line support, verification, format adaptors, multimaster sync..)
How to Get Involved
Most of our volunteer needs are for remote mapping and project work. To find out more about what HOT does and how to get involved see the HOT Guide
Learning to Map
The largest volunteer need of HOT is for OpenStreetMap contributors. To get started contributing to OpenStreetMap, the community has developed a simple-to-use beginners guide called LearnOSM (learnosm.org). A series of quick lessons will guide any new user through setting up an account and beginning to map. New material is always being developed and added.
What to Work On?
Notice: A formal definition of various HOT Programs (humanitarian projects and activations) is being developed, see HOT activation for information regarding urgent response.
Humanitarian projects can be the immediate responses to natural disasters, political crises and other destructive events or projects designed to mitigate or plan for disaster risk or economic development. They are launched where up-to-date geographic data is needed and where OSM data currently is being used or will be used by local communities and/or responders. Generally, these projects are launched by active participants in the HOT community who will coordinate the remote mapping with the needs of humanitarian actors and other first responders, and with any local OSM community as guidance. If a situation becomes complex, individual(s), humanitarian actors or local communities are encouraged to reach out to the HOT Activation Working Group. If the working group decides that HOT currently has the resource and capacity to facilitate the request, it will announce an official "activation," which indicates that this crisis is a high priority for the organization. The team also may invite other NGOs to collaborate, make requests for needed resources and will document the progress and conclusion of the activation. These decisions take into account which humanitarian mapping projects and/or activations HOT currently is supporting or monitoring, as well as the potential impact on the project beneficiaries and our current capability to provide assistance.
Organised Editing Projects
Please see our dedicated wiki page for organised editing projects led by HOT. These include both remote digitising projects and community led projects on the ground.
The Tasking Manager
The Tasking Manager is a tool that divides large mapping tasks into small sections to make them easier for volunteers to manage. The Tasking Manager also includes background information on the locale to be mapped, as well as information about what kind of data is needed (road, schools, etc., and how to recognize them). Volunteers can contribute directly to current activities through HOT's Tasking Manager.
See HOT Tasking Manager Organizations for a list of organizations which are present on HOT's Tasking Manager. If your organization is not listed there and you'd like to create projects on HOT's Tasking Manager, please complete this form to register your interest.

Global Volunteer Community
There are many ways to contribute to the mission of HOT. See the HOT Guide for the basics. All we ask is that contributors govern themselves using our Code of Conduct, which is found on our website: HOT Code of Conduct
Dedicated volunteers who have been elected and make up the voting community are listed here:
- Main article: Humanitarian OSM Team/Members
Membership Code can be found here.
Board of Directors and Officers
HOT's Board of Directors (Board) is elected from the membership. Information about the Board can be found at the Board page.
Sub-pages include current and previous Board members, as well as links to all previous Board election documentation.
Board Meeting Minutes and Board documents (such as Board Annual Reports, Board President's Reports and Board Procedures) can also be accessed from the Board page.
HOT's name, legal name and registration
The Humanitarian OpenStreetMap Team (or HOT for short) is registered in the USA as a 501(c)(3) charitable organisation under the legal name HUMANITARIAN OPENSTREETMAP TEAM UNITED STATES INC (see Legal Doctrine for documentation). The usage of the OpenStreetMap mark in HOT's name is currently being clarified between HOT's executive director and board and the OpenStreetMap Foundation board. The usage of the phrase is not meant to imply that HOT has any direct affiliation with the OpenStreetMap Foundation beyond that agreed between the two organisations.
- Humanitarian_OSM_Team/U.S. Bylaws
- Humanitarian_OSM_Team/U.S. Articles of Incorporation
- In March 2013, HOT was officially recognized as a 501(c)(3) charitable organization.
- Many issues and plans emerged from the Haiti response, leading to a medium-term plan for HOT. Access the Humanitarian OSM Team/Haiti Strategy And Proposal for more information.
Solving global challenges requires an understanding of our physical environment that is grounded in direct knowledge and observations. Open mapping helps us build that understanding together, which enables humanitarian, development, and community organizations to take more informed and locally appropriate action. Impact Areas connect open mapping with real world applications through spatial data use in the humanitarian and development sectors. Each impact area at HOT provides a framework for technical and subject matter expertise for partnerships, grantmaking, and community support.
Our humanitarian work is centered on 5 Impact Areas which are;
- Disasters & Climate Resilience
- Sustainable Cities & Communities
- Public Health
- Displacement & Safe Migration
- Gender Equality
Are you working with OSM in one of HOT’s impact areas? We’d love to hear from you on what data you are using, what analysis has worked, and other feedback at firstname.lastname@example.org.

The Missing Maps Project
The Missing Maps Project is an open collaboration founded by HOT, Medecins Sans Frontieres / Doctors Without Borders (MSF), American and British Red Cross. It aims to map, within two years, the parts of the world where the most vulnerable people live. Building on the excellent work done by OpenStreetMap and others in emergency-response mapping, the Missing Maps Project aims to map in a proactive way. Instead of responding to a natural disaster, conflict or epidemic, it will identify regions vulnerable to crises will map them in anticipation of crises. This means that, when a crisis does occur, local people, NGOs and other responders can start using the maps and the data immediately, saving valuable time and, potentially, lives.
Visit the Missing Maps website for more details.
The Humanitarian OpenStreetMap Team (HOT) Community Support Program supports local people to leverage OpenStreetMap (OSM) data, tools and community to help solve local challenges. One of the ways in which we do this is by providing OSM communities with microgrants to support local mapping activities.

How we think about data quality at HOT
There are many organizations, communities, and individuals that contribute data to OpenStreetMap and all have a different background as to why they contribute to OpenStreetMap. Some contribute because they are doing research, academic or spatial analysis and the context of data quality is looked at differently. HOT contributes to OpenStreetMap from the perspective of humanitarian and from our side, the perspective of data quality is OSM data has to be fit for purpose; it must be able to address and inform the most critical and impactful use cases and decision-making to aid our (humanitarian) partners and communities’ use of maps and data.
It is therefore our concern to understand what fit for purpose is in terms of humanitarian response and how we maintain the quality of existing OSM data and improve the quality of new contributions. HOT’s global data Team leads on Quality Control & Assurance, pulling the Data Quality strategy with the HOT regional hubs, supporting the open mapping communities, coordinating data quality internships, conducting training and preparing training materials, and giving feedback to contributors.
Our approach to data quality - what we do to promote good data quality
Bearing in mind that it is paramount to contribute good quality data to OpenStreetMap, a number of tools, processes and workflows and resources have been developed to enable mappers to improve the OSM contribution., etc
Processes and workflows
- Data cleaning
- Improved project creation
Data Quality Internship Program
Data Quality Internship is an annual program that was established in 2020 with the main objective of supporting and raising not only great mappers and validators, but also leaders and advocates of open data, open mapping, and OpenStreetMap. Please watch out for the 2023 Data Quality internship program and don't miss the opportunity.
Data Quality Issues
HOT has prioritized top 10 data quality aspects in line with our intended humanitarian and development uses, in which we want to minimize errors. These aspects have been categorized under 3 categories - Positional Accuracy, Semantic Accuracy, and Completeness. HOT is focusing on prioritizing these aspects and implementation on how to minimize/eliminate them through HUB-centered community engagements in form of trainings, collaborating with partners, and developing tools that can be used to improve the quality of mapping.
top 10 data quality aspects include;
- Spatial offsets.
- Temporal inconsistencies.
- Feature tracing inconsistencies.
- Road network inconsistency.
- Completeness of health facilities.
- Completeness of public service data for sustainable communities.
- Administrative boundary inconsistencies.
- Logical inconsistencies of map features.
- Tasking Manager project inconsistencies.
