Every year during the rainy season, the largest city in Tanzania, Dar es Salaam, suffers from devastating floods that wipe out roads, destroy houses, and result in deaths, sickness, and millions of dollars worth of damages. By helping communities to map their wards, the Ramani Huria project is able to support disaster prevention and response to areas that were previously off the map, literally. One key element of these maps is drainage systems. We have dedicated mappers working to ensure these, as well as wetland zones and flood-prone areas, are included accurately in our maps.

Inspired by our response to the West Africa Ebola epidemic, a grant was generously made by the Hewlett Foundation to HOT in late 2014. This funding was aimed at improving the ability of HOT to fulfill its large scale and long running Ebola response, as well as have the capacity to respond to future events. It was determined by the community that the grant be divided and focus on three projects, addressing the development of the online tools Field Papers and the Export Tool, as well as building the numbers of Activation Coordinators.

  As the new Export Tool has been successfully rolled out, the earlier version is to be switched off as it is held on the GeoFabrik servers and we will no longer be enlisting their generous services. We will create a read-only version of the old Export Tool and host it on the HOT servers alongside the new Export Tool.

HOT, in coordination with the OSM MX community, has been active the past two days tracking the hurricane's progress and mapping vulnerable areas in its path. We have two mapping tasks open on the OSM Tasking Manager ( a task covering coastal areas in the storm's path and a task mapping more inland areas. We do not anticipate opening additional tasks but we are monitoring the situation in case landslides, floods or other post-hurricane hazards create additional humanitarian situations we can contribute to.
