HOT in Chad
HOT started its activities in Chad in October 2012, conducting a mapping project in Southern Chad (Goré), as part of the EUROSHA project together with ACRA and France Volontaires. The initial focus was on baseline mapping of Goré and surrounding refugee camps and villages. Lately the EUROSHA projet's activities expanded to other Chadien towns - Maro, Doba, Moundou, N'Djamena and Mongo. The field activities of HOT and of the EUROSHA volunteers were finished in April 2013.
All these activities are meant to support the growth of a local OSM group in Chad and the growth of the OSM project Chad.

If you have a goal that you are working towards or one that you would like to see get done then add it to the list here, create a section where it can be coordinated and tracked, and a way of measuring progress.
- Place names. This item is especially important if you are located in Chad: remote mapping can do a lot, but finding local names is best done on the ground.
- Street layout of major cities. Ndjamena, Goré are taking shape nicely, but other cities (Moundou, Doba, Maro) are barely getting started.
- Completion of the network of major roads, including roads to neighboring countries.
- Data to import in OSM.
- Data quality
Where & what to Map
- Maro and refugee camps with their surrounding villages
- Harazé and refugee camp with their surrounding villages
In the following table you can find the list of jobs that have been created in the HOT Tasking Manager in order to better coordinate the remote mapping activities for Chad. Feel free to participate in remote tracing of buildings, roads and areas.
|Place||Tasking Manager Job||Tasking Manager Progression||Comments|
|N'Djamena||EUROSHA Chad N'djamena job 1: mapping roads and buildings.||4%||We need more mappers to continue in this job as well as to check the already existing data quality.|

Field Mapping (MSF project)
MSF's principal medical activity in the district of Moissala in southern Chad is to provide preventative and curative care for malarial infection for pregnant women and children under 5. In 2015, MSF is planning a pilot activity of indoor residual spraying (IRS) in the eastern zone of Moissala to further increase the prevention of Malaria for families who are isolated on the other side of the Bahr-Sara River, far from the referral hospital. The first round of spraying is scheduled for April 2015.
The logistics team in Moissala is working hard on a detailed map of the 133 villages in the zone in order to plan for the month-long spraying campaign with the help of local volunteers. Mapping the area will greatly help the team effectively plan their movements between villages and ensure they are able to reach all households and further decrease the transmission of this deadly disease for the population.
They have collected the field data below and we need to add it to OSM.
Note, this is not a task on the HOT tasking manager and should be managed by editing the table below to indicate that you are working on a Canton.
In the following table you can find the data and gpx data (by Canton) and the associated survey. Please upload the tracks and points to JOSM, then trace any missing roads and residential areas, and add the village names.
|name=*||The name of the village|
|is_in=*||The name of the canton (for example, Bekamba)|
Please remember to indicate if you have started to work on any of the cantons listed by editing the table below. One canton per person please to prevent duplication!
|Bekamba||GPX and survey data for Bekamba||Pete Masters||Done|
|Gabian||GPX and survey data for Gabian||Lisa Marie Owen||Done|
|Dembo||GPX and survey data for Dembo||Pete Masters and Laura Green||Done. Some unsurveyed villages found on the Bing imagery south of Mangara by the river (named 'missing village')|
|Nadili||GPX and survey data for Nadili||Pete Masters and Laura Green||Done.|
Please use the default Bing imagery to help with the digitisation. Please add the following as the changeset comment: Moissala, #Chad #FieldMapping, #MSF, #MissingMaps, source=survey
Imagery and sources
Bing coverage for Chad is available at a high resolution in many areas including Ndjamena, Moundou, Doba and Goré. It does not need to be offset and the imagery is relatively recent 2010-2012.
Historical maps from the Perry-Castañeda Library Map Collection provide resources - make sure you cross-check them.
