Round 10 of the Outreachy program has come to an end! Running for three months, from the 25th May till the 25th of August, the interns were involved in a number of key HOT OSM projects including OpenAerialMap, the Tasking Manager, the Export Tool and LearnOSM. To find out more about their work, please see our Outreachy page, which provides links to their individual blogs. The interns will also be presenting their projects to the community on Wednesday the 16th September to those who are interested on hearing more about their great work. Please look out for an email and tweet about the exact time and ‘virtual’ location where it will be held. On behalf of HOT and the OSM community, we would like to thank all the interns for their invaluable work, and Outreachy for making it all happen.

Small Unmanned Aerial Systems (sUAS), also known as drones or UAVs, are revolutionizing the way we do remote sensing and aerial imaging.  With less than $1,000 needed to build or buy one, anyone can now put a camera in the sky and collect images that mosaiced together allow for detailed mapping and modelling of the earth's surface. These systems are becoming the preferred tool of GIS professionals to survey small sites rapidly and affordably. Digital humanitarians are seeing the same opportunity and are now flying sUAS after disasters to improve damage assessment or during preparedness projects to support local community mapping.

During the recent Nepal earthquakes, digital humanitarians were suddenly flooded with data, a lot of data, especially aerial imagery collected with satellites and small unmanned aerial systems (sUAS, also known as drones), and openly shared with anyone.

HOT has been developing an 'Activation' training curriculum over the last several months in order to build and improve the skills of it's 'Activators'. This was all made possible by a generous grant from the Hewlett Foundation who were inspired by the West Africa Ebola epidemic response and wanted to contribute to improving HOT's capacity to support future events. As part of the grant and the development of the curriculum, two workshops will be held in order to train and certify activators, as well as receive first hand feedback for further improvements. The pilot workshops will take place in Dar es Salaam, Tanzania and Jakarta, Indonesia in September later this year. Designed as a three-day course, the participants will be guided through the on-line open curriculum, learning the necessary theory and skills it takes to support a HOT activation before engaging in a simulation where this newly gained knowledge can be put into practice.

The "Dar Ramani Huria" Scale Up Workshop took place at Nkrumah Hall, University of Dar es Salaam, on Monday 6th of July. Over the next three months, the Ramani Huria project ‘Community Mapping for Flood Resilience’ will be building on previous work and expanding its mapping activtities to 10-14 additional wards across Dar es Salaam. "Dar Ramani Huria" (Dar Open Map) is the local name of the "Community Mapping for Flood Resilience" project run in Dar es Salaam, Tanzania by HOT.

  Aerial imagery is key to the work that HOT undertakes each day of the year. During a crisis, the need becomes even more acute. Pre-disaster imagery helps HOT volunteers all over the world trace homes, buildings and the road network into OpenStreetMap; enabling first responders to carry out search, rescue, and relief activities. Post-disaster imagery facilitates identification of damage to roads and buildings and can serve as a first step in identifying camps and temporary shelters for internally-displaced persons. The response of the international community to the Nepal earthquake was unprecedented. More than 7000 volunteers helped trace satellite and aerial imagery to create base maps used on the ground, initially for relief and now for recovery. This simply would not have been possible without the generous support of the imagery community.

This year has presented many challenges to HOT. We have been incredibly active and successful in all of our programs: Disaster Mapping, Community Building and Technical Projects. However, as many of you know, 2015 has been a year of tremendous change in HOT leadership.
