Hey Mikel, Just may be to give an info, the road had been collected through Landsat images observation and completed with GPS field observation. Some of the logging roads had been provided by the timber companies, sometimes one track for a network of roads. As I mentioned yesterday to the Eurosha-team, I will be providing the latest road network we have for CAR and DRC, from late 2012. It won’t be helping at a town scale but more at the national scale. I also would be interested to participate to a mapping party if this can help. Best regards, Pascal

I've been working with this data as well in another context, and we have noticed good accuracy in many places, varying accuracy in others. So data import should be constructed as not only conflation with existing OSM data, but also comparison to other data sources (bing imagery, as it is ... though can be hard to judge with the canopy). And even better would be involvement of the community of folks who are working with this data in Central Africa, and here in DC. If we can develop a community around this import, and the ongoing improvement and use of the data, going to be a strong initiative. There are several organizations here, and WRI is hq'd here. I don't know as much about WRI's operation in Central Africa, and how the data was originally collected, but what I'm thinking about is something like a series of multi-city, time focused, mapping party activities.

About the license: the data of the World Resource Institute is compatible with the license: ODbL. We got the signed permission from Pascal Douard from the World Resource Institute. You can find the authorization in the attachment. At this moment we are also working on a wiki page with more information about the data (http://wiki.openstreetmap.org/wiki/Central_Africa_Import). After our first analysis of the data, we considered the data of very high quality. For Cameroon it is even the best data we have in comparing with all the other data we could collect. You can find their data on the website of the WRI, but the specific links to the data of which we have the permission; you can find it on the authorization in the attachment. Pascal also promised us to give us, as soon as possible (after their verification), the latest version of the data of the road network of the CAR and the DRC. Best regards, Jorieke Okay... the attachment is not working... but you will find the authorisations soon on the wiki! 2013/3/25 Pierre Béland <[email protected]<mailto:[email protected]>> Hi Jorieke This is very interesting to have the possibility to collaborate with people on the ground and use eventually imports to have a better map. In the context of humanitarian activations, it is important to work in a coordinate manner and discuss before such imports are done. First, we have to be careful and before importing any data into OSM, we have to follow a strict procedure to assure that the data is published with a license compatible with ODbL. We have to know the original producer of the data, how it was collected, and evaluate how good is the georeferencing. We also have to validate if the license is compatible. Do you have any information about that? I coordinate the current activation in DR Congo with Claire Halleux. I would like to look at the data that is contained in these files and see how it can help us for the DRC Activation before anything is setup with these files. Could you please send me a copy of this data?

We are really glad to see your activity on the current crisis in the Central-African Republic. At this moment we are working in Cameroon, for Cameroon, but of course also for the CAR! Last week we obtained the permission to use the data of the World Recourse Institute (WRI) for the CAR and the DRC. This data (localities, road network, etc) can be very useful for the humanitarian actors on the field at this moment. For this reason we are now busy with setting up as soon as possible the importation process. And it is in this we need some help of you guys. Because we don’t really like the massive data importations as this would conflict with the existing data and could get very messy, we propose a crowd-sourced way to verify and import the data using the tasking manager. We have converted the existing shapefiles to OSM-XML format already and have setup a service that can serve the data into JOSM as follows: http://www.osmsharp.com:815/data/16748/10966/15/matrix.osm The data served is just a test area; the real converted data will be there soon. A request like this will return only data inside the requested tile. Any existing OSM file can very quickly be served on the site this way. We think it would be a very efficient and nice way to process and convert the data into OSM using the tasking manager if we could add a field or link to it that could load the data from the above url straight into JOSM or provide it as a download link in the task itself. Using this method all the humanitarian-relevant data can be converted and imported very quickly. But this means we need help from somebody to modify the tasking manager just a little bit to make this possible.
