In Niamey along with members from OSM Communities from Niger, Benin, Burkina Faso and Togo, with the support of Organisation Internationale de la Francophonie, we have been coordinating since last Monday a couple of two-weeks long workshops about free Geomatics tools and opendata, for the benefit of Geography students and professionals from various backgrounds. As usual, we will organize a mapathon during the first Saturday, involving all the workshop participants and members of local OSM community. We will continue the work the days after, at least during our "maptimes" when starts every new training day.
The area has been identified by OCHA Niger with the aim of using the data produced during a two-days workshop including InaSAFE for the local IM GIS Working Group they lead: the Diffa Region on the Southern-Eastern part of the country around the border with Nigeria, unfortunately affected by frequent terrorist attacks from Boko Haram.
Analysing the existing OSM data shows almost all the inhabited places have been mapped as residential areas. Extracted with Overpass, they allowed us to create a large Tasking Manager project focused only on them. A priority area has been added between Diffa and Bosso (see in pink) thanks to the recent UNOCHA maps and OCHA Niger IM GIS request.
The goal is to map all the buildings and huts in order to use InaSAFE to get impact scenarios of attacks on both structures and the population (estimated from the buildings) as we did last week in Mali for the flooded area in Markala.
For sure the tasks are numerous on this priority area but many of them are quick and easy to achieve considering the hold only a few buildings.
