Four regions, five years, 94 countries, one billion people

In 2019, the HOT community developed a Strategic Plan, which stated an audacious goal: to map an area home to one billion people in OpenStreetMap. But one key question remained: where?

What if we could map an area home to one billion people currently missing from the world’s maps?

HOT’s Journey through Salary Transparency

In September 2018, HOT held an in-person meeting of staff alongside our annual Summit in Dar es Salaam, Tanzania. After gathering ideas from staff, we ran a survey. The results: highest priorities for improvement were salary, benefits (specifically health care) and learning. This is the first post about what action we're taking based on what we heard, focusing on what we believe is a major leap forward for HOT: salary transparency.

HOT Endorses the Principles for Digital Development

In October 2018, HOT officially endorsed the Principles for Digital Development, joining just over 100 organizations who have done so to date. The Digital Principles are nine “living” guidelines designed to help digital development practitioners integrate established best practices into technology-enabled programs. The Principles focus heavily on many of HOT's core values, including community, openness, collaboration, and innovation and will continue to guide our work going forward.

HOT Joins the Group on Earth Observations

In July, HOT was voted in as a participating organization of the Group on Earth Observations (GEO). Forums like GEO that emphasize sharing of free and open Earth observation data are critical to evolve the methods and standards to make data and information more accessible. GEO is building the Global Earth Observation System of Systems (GEOSS) to connect the world's environmental and socio-economic data sources. Membership in the global data-sharing body brings opportunities for HOT to contribute to use of Earth observation data and information for better decision-making.

HOT's Commitment to the Sustainable Development Goals, and How You Can Help

When I speak with HOT staff and volunteers in our community, I often ask what they've heard about the Sustainable Development Goals, or SDGs for short. Sometimes, people have heard of the term, or know that the term is somehow related to the United Nations. I often chat about the types of mapping projects they're working on. In the past month, the answers have been incredibly varied: HOT staff are mapping safe bicycle routes and access to sanitation (public toilets) in Tanzania; banks, ATMs, and mobile money agent locations in Uganda, and are about to start mapping critical disaster "lifeline" infrastructure in two of the biggest cities in Indonesia. In addition, HOT volunteer leaders are working on dozens more projects throughout the world across sectors: education, environment, health, transportation, water and sanitation. These projects are all taking place in challenging contexts: megacities in developing countries, refugee camps, and unplanned urban and rural housing settlements.So what does this have to do with the SDGs?
