The initial focus is on baseline mapping of Bangui and the regions in which the needs are most crucial. All these activities are meant to support the growth of a local OSM group in Central African Republic and the growth of the OSM project. In December 2012, considering a rebellion took a great number of cities in the country, the EUROSHA Project has been canceled in the country and HOT activated the OSM communities in order to map specific areas of interest for the humanitarian community (see Current activities) with specific Tasking Manager tasks (see below). The residential areas of these towns have been 80-100% mapped, except for Bambari (20%), only covered by Orbview3 imagery. On March 24, 2013, after months of relative statu quo along with violence in some towns, the Seleka rebels took over Bangui, ending the hope to see the situation to go back to normal. A HOT Activation has been started to map Areas of Interest and start importing the humanitarian data provided by UNICEF (see below the Data Imports section). [modifier] RCA crisis - HOT Activation - mapping goals [modifier] Highlights In November 2013, the UN warned the country was at risk of spiraling into genocide and France described the country as "..on the verge of genocide." The increasing violence was largely from reprisal attacks on civilians from Seleka's mainly Muslim fighters and Christian militias called "anti-balaka", meaning 'anti-machete' or 'anti-sword'. Christians make up half the population and Muslims 15 percent, according to the CIA World Factbook. As many Christians have sedentary lifestyles and many Muslims are nomadic, claims to the land were yet another dimension of the conflict (source: Wikipedia) Useful links to get more info about the situation in the country: The Wikipedia page Central African Republic conflict (2012–13) relates the events since the rebellion rose up. The ReliefWeb page for CAR gathers all the maps and reports made by the humanitarian organizations. The last UNICEF situation report, dated December 5-7, 2013. The Human Rights Journalists Network for CAR website (in French) provides a lot of news from the field The Diaspora Multimedia & Audiovisuel is a communication agency in CAR that publishes a lot of pictures in its Facebook page The Humanitarian and Development Partnership Team (HDPT) unites all organizations working to alleviate the humanitarian and development crisis in the Central African Republic (CAR). They post several articles (in English and French) a day concerning the situation in CAR on their facebook page. The facebook page of the United Nations in the Central African Republic provides also a lot of news (in French) about the situation in the Central African Republic. [modifier] Ongoing: Mapping of affected cities and towns As part of a HOT activation, mapping selected towns affected by the rebellion starting in December 2012 with satellite imagery, based on Areas of Interest identified by local humanitarian stakeholders. Go to the HOT Tasking Manager and map tasks in the featured jobs. Regarding what has done so far, see the table below and please edit it after every contribution. [modifier] Ongoing: Mapping the country main frame: roads, place names and residential areas Providing a consolidated road network is one the main aims of this activation. Unfortunately, the country is not fully covered by high resolution Bing imagery. It may occur some extra imagery would be released. To map the road network efficiently, different tools are being tested. Please provide any feedback of useful tools that would serve this purpose on the hot arobase openstreetmap.org talk list. It would make sense to map the residential areas while mapping the roads, taking the time to map quickly a landuse=residential around every crossed village or hamlet. For the place names, see Populated Places section]. It would make sense to use the GNS files when importing UNICEF data (see next section), so that the two datasets tend to offset together their potential inaccuracy. [modifier] Ongoing: Importing UNICEF data UNICEF authorized the import of their data covering the western half of the country, and made of the following: UNICEF data for health facilities. Data coming from 2012, constituted of 342 nodes spread on 6 regions (half a country). UNICEF data for schools. Data coming from 2012,constituted of 934 nodes spread on 6 regions (half a country). UNICEF data for water points. Data coming from 2012, constituted of 1937 nodes spread on 6 regions (half a country). The way to process the imports has been described in this page As imports are a relative complex process that requires experience, the TM jobs supporting the imports are not open to anyone. If you are interested to contribute, please send an email to hot arobase openstreetmap.org. [modifier] Done: Mapping Bangui and Zongo Bangui has been intensively mapped by the EUROSHA volunteers during their deployment in the country. Use this Tasking Manager job to complete and validate the tiles. The northern parts of Bangui are still to be mapped. Following the Rebellion in Bangui, numerous refugees are crossing the border to DR Congo. The area around Zongo needs to be mapped in detail to help humanitarian organizations. A specific TM job has been created.

Based on this methodology, we can consider that the road connecting the capital cities of prefectures should be tagged highway=primary. Theses cities are: Bangui, Bozoum, Bossangoa, Berbérati, Bimbo, Bambari, Mobaye, Mbaïki, Bouar, Bangassou, Sibut, Kaga Bandoro, Nola, Bria, Obo, Birao, Ndélé. A list of prefectures with population census can be found on Wikipedia. The Bing high res imagery is sometimes missing, but it might happen the road is nonetheless visible on the low res, LandSat based, imagery. It then can be complemented this way, but a fixme tag can be added to point out the bad accuracy. highway=secondary would be dedicated to road joining Préfectures and Sous-préfectures or Sous-préfectures together. Sous-préfectures can be tagged place=city or place=town considering their population. As a first step, we will start by creating or completing the primary road network linking these prefectures capital together. If someone considers that extra cities should be added considering their economic importance, this can be discussed over the HOT list. The admin levels for CAR have been proposed this way, to be discussed. According to Proposed_tag:capital, the prefectures should then been tagged capital=4 and the Sous-prefectures places capital=6 Missing road section OSM view Approx.

Village locations were taken with GPS in a systematic way." Unfortunately, as the source of this data is mixed and sometimes unknow, it appeared to be not compatible with ODbL and thus cannot be imported in OSM. The only ODbL compatible gazeeter known so far is the NGA Country file (GNS) for CAR, that counts 17,000+ places (not only populated, but also hydrographic, administrative, vegetation, etc., as explained in the metadata). It is unfortunately, generally outdated and tests showed the accuracy is not very precise, but nevertheless it is a good source of information to be compared with the places hold in the UNICEF humanitarian data (see the import section). The data will be proposed on a specific Tasking Manager job as a downloadable file gathering the Populated Place spread into each grid extent. Most of time each populated place is close to a specific populated landuse visible on Bing imagery. Towns, villages and hamlets have to be create at their exact location, approximately in the middle of the populated landuse. This latter has to drawn and tagged and a landuse=residential.</strike> [modifier] Quality control You can participate by checking the mistakes with Keep Right! or Osmose.

[modifier] Imagery & sources Bing coverage for Central African Republic is available at a high resolution in many areas including Bangui, Bangassou,Bamingui, Berberati, Bambari, Batangafo, Bria, Kabo, Kaga-Bandoro, Ippy, Birao, Mbaiki, Ndele, Mrbes, Ouadda, Ouanda Ndjalle and Zemio. The imagery is relatively recent (2011). Bambari is not covered by high resolution Bing imagery but there are 2 Orbview-3 images covering it. These two images, with enhanced contrast, are available online from OpenStreetMap France imagery server, as TMS and WMS. For JOSM, add the following TMS supplier in Preferences/WMS-TMS/+ : tms[19]:http://wms.openstreetmap.fr/tms/1.0.0/centrafrique/{zoom}/{x}/{y}. For Potlatch2, add the following background: http://wms.openstreetmap.fr/tms/1.0.0/centrafrique/$z/$x/$y. Check the quality of the imagery with Bing Image Analyzer [modifier] Information To get information on the situation in the field you can consult: the Network of Journalists for Human Rights in Central African Republic website(in French) who publishes a lot of located news and hosts a Crisis Map - CAR, using Ushahidi the Humanitarian and Development Partnership Team website, that collects the different humanitarian reports and maps about CAR. HDPT gathers all the humanitarian and Development stakeholders in the country and have weekly meetings.
