<br></div>There have been about 120,000 nodes that have been added in the Philippines in the past 2 days. Though I don't have the exact numbers, that probably translates to around 20,000 buildings. The rest would be new roads, rivers, landuses, and improved coastlines.<br>
<br></div>There have been at least 60 mappers editing in the Philippines in the last 2 days. The previous spike in the number of editors was in mid-October after the 7.2 earthquake that hit Bohol (<a href="http://tasks.hotosm.org/job/326">http://tasks.hotosm.org/job/326</a>).<br>

</div>I agree that wider coverage will be needed and I had hoped that by now<br>
we would have a better indication of where to map as well. My reason<br>
for staying with Tacloban for so long was largely due to lack of<br>
knowing where else to shift focus to (although I did allude to this a<br>
bit by suggesting the other villages on the coast northeast of<br>
Tacloban), more importantly due to a second fact...<br>
<br>
When we map an area, it is only really useful for us to map areas that<br>
the aid organizations we work with will be responding to. For the aid<br>
organizations that don't know about, or don't know how to use, our<br>
map; then no matter how good the coverage is, it doesn't help them.<br>
This is the main reason I chose to focus on Tacloban. It is badly hit<br>
(as were many other places as you rightly point out) but it is also a<br>
provincial capital, and it is the largest town in the immediate area.<br>
Because of this I figured that most of the international response<br>
would likely be directed there, and since it is mostly the<br>
international orgs that we tend to work with I figured the map data<br>
would be most useful there.<br>
<br>
Now, that being said I want to make it clear that the explanation<br>
above is not necessarily an argument for continuing to focus entirely<br>
on Tacloban, just merely an explanation of why I hadn't directed<br>
people elsewhere yet. I agree that we will need to spread out our<br>
efforts at some point, and that point may be approaching, the question<br>
is where to focus next. As I mentioned previously, I think the<br>
villages along the coast to the northeast will be hard hit (and due to<br>
their proximity to Tacloban will likely receive international aid).<br>
There are also villages along the coast to the south of Tacloban that<br>
will have been hit hard as well since the eye passed directly over<br>
them. The eye track will likely have done the most damage, or the<br>
area to the north of the eye track since the storm rotates<br>
counterclockwise as it moves westward.<br>
<br>
If anyone has better suggestions of where to spread out to I am<br>
certainly open to them. Like I said I am not saying we need to stay<br>
at Tacloban (and the surrounding area) just explaining why I was<br>
continuing focus there. I know the storm affected a lot to the west<br>
as well but I figured this would be trickier to map for two reasons.<br>
1) it is a larger area with not such and obvious target for<br>
international aid, and 2) the wind speeds were lower to the west due<br>
to the storm being disrupted by the islands. As for the idea of<br>
mapping the area affected by the earthquake to the south, my<br>
understanding (and this could be wrong) was that most of what we could<br>
do remotely has already been done when the earthquake hit.<br>
<br>
So that is all of my reasoning at the current time for our current<br>
focus. I hope to begin hearing more concrete info from aid orgs today<br>
so I might redirect people when I hear from them, but for now my<br>
advice would be to try to continue with Tacloban (especially the low<br>
lying areas) and simultaneously spread out into the surrounding<br>
villages until/unless we get something concrete from an aid org.<br>
