<br>
As you may know, helicopters play a critical role in bringing help to<br>
Nepalese people affected by April 25 7.8 earthquake, and May 12 7.4<br>
aftershock, with roads blocked or made dangerous by landslides and<br>
unstable terrain.<br>
<br>
A USMC helicopter that was taking part in this effort is missing since<br>
May 12. Other helicopters involved in the search and rescue mission<br>
report that: "A primary concern for ongoing search and rescue efforts is<br>
unmarked high tension power lines, which have been reported and bisect<br>
many of the valleys in the search area".<br>
<br>
Some high tension power lines have already been mapped<br>
(<a href="http://overpass-turbo.eu/s/9lx" target="_blank">http://overpass-turbo.eu/s/9lx</a> , passed along to those conducting the<br>
searches). Starting from electrical dams makes it easier to spot them.<br>
<br>
If mappers experienced at mapping power lines could give a hand, this<br>
would be great. (Or others willing to learn, like me :) ).<br>
<br>
Bing is available for large parts of Nepal. A focus for current search<br>
and rescue effort is around Ghorthali (27.7517 N 86.0342 E) from where<br>
a Nepalese local reported seeing a helicopter crash. But of course high<br>
tension power lines would also be nice to have for Sindhupalchowk,<br>
Dolakha and other affected districts (see<br>
<a href="http://kathmandulivinglabs.github.io/quake-maps/" target="_blank">http://kathmandulivinglabs.github.io/quake-maps/</a>).<br>
<br>
(Please download and upload OSM data often, in case other mappers work<br>
on the same theme).<br>
<br>
Thanks,<br>
<br>
Jean-Guilhem<br>
