-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Séverin, Nicolas and all:
Thanks Séverin for sharing this ITO map. I wasn't aware of this 90 days ITO service; I find it very cool and useful. And yes: it's really impresive, even for me! Sorry for answering so late, but I have arrived home last week after long and, going here and there with family and friends, I couldn't find the time to sit down and put all info and data in order, so I could adequately answer about what has been done and what the next steps will/could be, with the hope that my answer can be useful and practical for anyone interested. My main goal in North Nigeria was to train staff in OSM editing with JOSM and other Q&A related stuff, so we could put the roads editing job for Kano State in the good track ( http://tasks.hotosm.org/job/474 ). For that purpose I also made a road classification proposal based on the official Nigerian classification and the Highway Tag Africa wikipage, that it is now incorporated to the Nigeria Wikiproject ( http://wiki.openstreetmap.org/wiki/WikiProject_Nigeria#Roads ). For discussion, I sent emails to the HOT mailing list, but especially to the user crackers250, who had done a great job in classifying and editing many of the primary and trunk roads, based in the Nigerian Gov. official classification. I also opened the (up to that time) non-existent talk-ng mailing list, hoping that more people mapping in Nigeria will join the list. But when I arrived in Kano, it appeared the possibility to import different kind of data collected by eHealth Africa during the last 2 years, so I opened a hackpad ( https://hackpad.com/hKeQZhVqQeR ) to evaluate all that data, that is indeed a huge geodatabase in itself. The first data that was imported was the boundaries for the wards and LGA's of the 10 Northernmost Nigerian states, and the boundaries of the LGA's of the rest of states of Nigeria. Every state of Nigeria is divided in Local Government Areas (Kano state for instance is composed by 44 LGA's), and every LGA is further divided in between 10 to 15 wards. LGA was tagged as district and wards as municipality for OSM. The import consisted on writing a script to convert the data to OSM and then the import itself ( https://wiki.openstreetmap.org/wiki/Import_Nigeria_eHealth_Africa_Boundaries , https://wiki.openstreetmap.org/wiki/Import_Nigeria_eHealth_Africa_Boundaries_%282%29 ). This was, by far, the most complicated and time consuming import. The second set of data to be imported was the residential areas for what they call in eHealth Africa build-up areas and cities ( https://wiki.openstreetmap.org/wiki/Import_Nigeria_eHealth_Africa_Residential_Areas ). The script for this import was really trivial, but the amount of data was really huge, and I had to deal with the merging of this data with the OSM server data, so it took quite a bit to finish the import. The third import is the health facilities import. We started with the import of the 1,087 collected health facilities for Kano State (other states (Katsina, Zamfara, Jigawa and Sokoto) will follow when a last Q&A control will be done for their corresponding data). This import is a work in progress. It is being done with a job in the HOT Tasking Manager (TM) ( http://tasks.hotosm.org/job/566 ) following a strict workflow ( https://wiki.openstreetmap.org/wiki/Import_Nigeria_eHealth_Kano_Health_Facilities_Workflow ) in accordance to its corresponding import wiki ( https://wiki.openstreetmap.org/w/index.php?title=Import_Nigeria_eHealth_Kano_Health_Facilities ). This workflow and TM job was set taking the UNICEF data import for Central African Republic as reference ( http://wiki.openstreetmap.org/wiki/Import_CAR_UNICEF_workflow ), a great job thanks to Séverin Menard and the EUROSHA project. Any experienced mapper is welcome to join the job, but please read carefully all the documentation before starting to import and edit. The forth import in mind is the import of the places nodes that we can extract from the residential areas data. The script to extract and convert the data is ready since long ago, and the import wiki is almost ready, so in the coming days I will submit it to the import list (as well as to the HOT and talk-ng list for comments). Only for Kano State there are 1,840 nodes. The import will be done similarly to the Health Facilities import, probably state by state. An import that could follow could be the Rural Villages place nodes (see RuralVillages.shp in the eHealth Data Import hackpad ( https://hackpad.com/hKeQZhVqQeR )). There are also other data to import, like schools, water facilities, etc. Some can be quite tricky if we consider the data as it is at present. As you can clearly see, all these is a huge amount of data, so it takes a big effort to do. And loads of data are being collected by eHealth Africa staff in the field, so it looks a quite non-stop job. During my last days in Kano, we could finally make contacts with people of the Geography Department at Kano University, but unfortunately it was too late for me to join in the collaboration between the university and eHealth Africa Foundation. One of the activities they were discussing was training students in OSM editing with JOSM and data collection with Field Papers. I will ask eHealth staff these days to know what's up about it. I also went three times (days) to the field, to see on the ground how data is being collected and uploaded to the servers. Finally, a job to map in detail the city of Kano was opened in the HOT TM ( http://tasks.hotosm.org/job/537 ). By chance, it seems some students of the University of Hidelberg (GER) have been editing in Kano as an excercise. Again, anyone one is very welcome to map the city of Kano. About making a presentation of all what it has been done, I would have to say that all data is being collected by many people in the field, in a quite difficult area (if you follow the news about North Nigeria, you will understand what I mean), and then processed by around 20 or more GIS eHealth Africa staff. I would obviously contact all the staff there before making any presentation of all this effort, as it is clearly not my only job at all, but the job of many. In my opinion, it would be nice to count with some of them for a presentation of what eHealth Africa is doing related with OpenStreetMap and the importance of their data being imported to OSM, not only for eHealth Africa, but for anyone with interest in Nigeria at present and in the future. A presentation in the next SotM in Buenos Aires? I can assure you that eHealth Africa Foundation is very happy of having decided to release their data to the OSM community, and will be happy to increase the collaboration with HOT and the OSM community in general. For me it was an amazing experience, and I will, no doubt, go on collaborating with eHealth and the Nigerian OSM community in whatever I can be of help. Cheers, Rafael Ávila Coya.
