-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I agree that wider coverage will be needed and I had hoped that by now we would have a better indication of where to map as well. My reason for staying with Tacloban for so long was largely due to lack of knowing where else to shift focus to (although I did allude to this a bit by suggesting the other villages on the coast northeast of Tacloban), more importantly due to a second fact...
When we map an area, it is only really useful for us to map areas that the aid organizations we work with will be responding to. For the aid organizations that don't know about, or don't know how to use, our map; then no matter how good the coverage is, it doesn't help them. This is the main reason I chose to focus on Tacloban. It is badly hit (as were many other places as you rightly point out) but it is also a provincial capital, and it is the largest town in the immediate area. Because of this I figured that most of the international response would likely be directed there, and since it is mostly the international orgs that we tend to work with I figured the map data would be most useful there. Now, that being said I want to make it clear that the explanation above is not necessarily an argument for continuing to focus entirely on Tacloban, just merely an explanation of why I hadn't directed people elsewhere yet. I agree that we will need to spread out our efforts at some point, and that point may be approaching, the question is where to focus next. As I mentioned previously, I think the villages along the coast to the northeast will be hard hit (and due to their proximity to Tacloban will likely receive international aid). There are also villages along the coast to the south of Tacloban that will have been hit hard as well since the eye passed directly over them. The eye track will likely have done the most damage, or the area to the north of the eye track since the storm rotates counterclockwise as it moves westward. If anyone has better suggestions of where to spread out to I am certainly open to them. Like I said I am not saying we need to stay at Tacloban (and the surrounding area) just explaining why I was continuing focus there. I know the storm affected a lot to the west as well but I figured this would be trickier to map for two reasons. 1) it is a larger area with not such and obvious target for international aid, and 2) the wind speeds were lower to the west due to the storm being disrupted by the islands. As for the idea of mapping the area affected by the earthquake to the south, my understanding (and this could be wrong) was that most of what we could do remotely has already been done when the earthquake hit. So that is all of my reasoning at the current time for our current focus. I hope to begin hearing more concrete info from aid orgs today so I might redirect people when I hear from them, but for now my advice would be to try to continue with Tacloban (especially the low lying areas) and simultaneously spread out into the surrounding villages until/unless we get something concrete from an aid org. - -AndrewBuck On 11/09/2013 05:25 AM, Jean-Guilhem Cailton wrote: > Hi, > > According to Al Jazeera, the death toll could be very high, sadly. > And several millions of people have been affected. > > I'd like to remind that an often-mentioned weakness of OSM is the > uneven quality of the coverage, and that it is not because you have > a hammer that everything is a nail. > > So, while Tacloban was indeed hit very badly, and a detailed > building map there is undoubtedly useful, it might also be useful > if some of the mappers who wish to contribute took a broader view, > to map, for example, some of the roads and villages that are > visible on (sometimes recent) high resolution Bing imagery > (http://osmph.github.io/Imagery_Coverage_Map/), but sometimes > still unmapped in OSM.
