The Northeast Nigeria has been affected for years now by a complex humanitarian crisis fueled by the insurgency of the Boko Haram group which has gradually gained in intensity and impact affecting over the past months its neighbouring countries and turning into a regional crisis (see ReliefWeb - Nigeria page).

Baseline data (places, residential areas and buildings as well as road networks) over this large affected region are needed for the various actors engaged in the response of this complex regional emergency. Several OSM initiatives have been lead in some areas (Nigeria's eHealth Africa data imports, mapping by local OSM groups from Niger and Cameroun, as well as the efforts of individuals) and individual efforts are still continuing. Discussions with humanitarian actors highlighted the relevance of OSM data in this crisis and the need for a continued effort.

Biu city and its district (Local Government Area) is one of the areas hosting more than 50,000 IDP's (Internal Displaced Persons) from the ongoing NE Nigeria Crisis at the moment.

The aim of this TM project is to map in detail the city of Biu.

The aim of this TM project is to map in detail the city of Biu.

  • Map all roads, street and paths, using the Highway Tag Africa as a reference.

  • Map also any river/stream in the area.

  • Check in the vector data is correctly aligned on Bing imagery, that is the reference for the georeferencing. Move/redraw the data if necessary.

  • Please trace ALL individual buildings and tag it as building=yes. Please SQUARE THE RECTANGULAR BUILDINGS if you do not use a mapping tool that does it automatically. With iD, you just need to click on the building once drawn and then a few icons show up as extra tools, and there is a square icon to square buildings. you can also type 'S' as a shortcut. Same thing for round buildings: there is an icon and the shortcut is 'O, to get perfect circles. For clusters of buildings, DO NOT enclose the whole area as one building. It is important to trace individual structures for future damage analysis. For that purpose, you may find this document useful.

  • Add source=Bing to the changeset
