eHealth Africa Foundation has different kind of geographical data that has just been released with an ODbL compatible license. The license is the HOT letter of authorisation that many of you probably know already.</div><div style="font-family:arial,sans-serif;font-size:12.800000190734863px">
Some data is probably very interesting to be imported. Among these data, we have the boundaries of all Local Government Areas (LGA's) and their Wards for 10 states of North Nigeria (Nigeria is divided in 36 states plus the Federal District of Abuja, each state divided further in a total of 774 LGA's (equivalent to districts), and each LGA is further divided in between 10 to 15 Wards (equivalent to municipalities)). The 10 states are the following: Kano, Borno, Yobe, Sokoto, Zamfara, Katsina, Jigawa, Bauchi, Kebbi and Kaduna.</div>

For example, the boundary of Kano state is missing a large area in the south, where three LGA's are mistakenly given to Kaduna state. Regarding the LGA's we noticed that only for a few of them a polygon was drawn. </div>

It is easily converted to .osm with the JOSM OpenData plugin. With an ad-hoc script we can convert the areas to relations, and add the corresponding tags. Then, we would import these data state by state, replacing the existing Maplibrary data. All the process would be carefully validated before being uploaded to the OSM database. As there are 10 states involved, the import would therefore consist of 10 changesets in total.</div>

eHealth Systems Africa Foundation (eHealth Africa) is a nongovernmental organization (NGO) dedicated to improving health care in developing countries through strengthening health workers and the systems that support them. eHealth Africa works towards this goal by creating sustainable eHealth and mHealth systems, providing technology infrastructure, performing training and capacity building workshops, publishing research on our work in Africa, and by providing consulting and support for other organizations working on health care in Africa. Based in Santa Ana, California, in the United States, eHealth Africa’s main office is located in Kano, Nigeria.</div>

eHealth Africa is supporting polio eradication in Northern Nigeria. A GIS is being deployed in Nigeria to help health workers collect data and target specific areas for immunization efforts in the fight to eradicate polio. High resolution satellite imagery has been used as a basis to map the communities. This work is currently mapping communities in ten Northern States. Subsequently vaccination teams will use the GIS to locate the communities. Using GPS technology the whereabouts of the vaccination teams are monitored and inputted into GIS to cross-check the mapped communities with the visited settlements. By doing that the GIS is updated with “missed” communities and the vaccination teams are guided.</div>

In 2011 the programme started in the 8 northern states of Nigeria (namely Kano, Borno, Yobe, Sokoto, Zamfara, Katsina, Jigawa and Kebbi), and the area has been expanded after that with another 2 states (namely Bauchi and Kaduna). Using high resolution satellite imagery and manual extraction of the features currently most of the states are finished mapping, while the rest is being worked on by the GIS department of eHealth Africa (consisting of around 20 GIS specialists). The mapping activities are focused on the collection and marking of each and every settlement in the whole area, since that information is required to provide polio immunization to the complete population. Besides mapping and naming all the settlements, the administrative boundaries are mapped as well as the roads, rivers, water bodies, health facilities, schools, mosques, wells, markets and more.</div>
