-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Frederik:
Thanks for your comments. I agree on what you say. I would add that I strongly believe in community building and mapping through surveying, and see imports just as a complementary way of adding data to OSM when (and only when) it's worth it and the other means fail. I already have done/organized several imports in North Nigeria, with eHealth Africa data ( http://wiki.openstreetmap.org/wiki/WikiProject_Nigeria#eHealth_Africa_Foundation_database_imports ), some of them very similar to this one of Liberia, and participated in others, like the UNICEF data import for CAR, both mapping and discussing in the imports list. I am not in charge of the activation of the West Africa Ebola response. It's Andrew Buck and Pierre Béland who are carrying this quite tiresome job since March this year (a big thank you for them!). Andrew announced yesterday in the HOT mailing list the release of this data, and asked for help on importing it to OSM, and I volunteered to do that. My comment "they need this data quite urgently" didn't mean we have to sort any issues with any deadline whatsoever. Some of my previous imports didn't need even a week of discussion, as no issues or almost no issues were raised. Some others need more time, and that is always very good sign, as it is always my goal to make the best import possible. On the other hand, giving these data to humanitarian organizations without having to publish it in OSM, and therefore making the data available in a faster although not so reliable way, is out of my scope, as I am not in direct contact with those orgs. But if I could help on that, I would surely contribute to that to. It should be Pierre or Andrew who would give you more data about this HOT activation but, following by memory, the response of the OSM community has been awesome so far, with more than 1,200 contributors plus something like 40 million objects mapped in the area (correct me if I am wrong). Some tasks, like the GNS places addition, were undertaken by experienced mappers in private jobs in the HOT Tasking Manager. I can't assure you about that, but I don't think it would be difficult to find experienced volunteers willing to contribute to this import. In the worst case, we can always abort it before it starts. I find your calculations a bit conservative. I've just done a test (no upload of the results) with 30 random nodes, and it took me just 15 minutes to complete (some had to be conflated, some others needed a fixme tag, some others needed downgrade to isolated_dwelling, upgrade to village, moved the location, or needed no modifications).I think the ratio of 1 node per minute is to long (bear in mind that roughly 50% of the nodes will be ok as they are, with no conflating, need of moving the node nor changing the place tag value). But, in any case, even if we take those calculations as the correct ones, having 5 experienced volunteers working an average of 6 hours a day, it would take a week or so. Quite good. I think it's quite feasible. In any case, whatever the time it takes to complete, every node that is imported will be already useful, and not only for this Ebola crisis. And I am surely committed, once the import is started, to make sure that it will be finished. Cheers, Rafael.
