Hi François
We need various expertises to answer quickly and produce data of quality It
would be great if you could extract the Nepal powers in the area of the
response around Kathmandu and revise the tagging schema.
And say Bonjour to the OSM Lyon contributors meeting at the charming Chez
Thibault café.
regard
Pierre

Objet : Re: [HOT] [OSM-talk] Mapping high tension power lines in Nepal
Hi,
The power generation model was refined in 2013 and include some distinction
between a power plant and a power generator.
It would be convenient and sustainable to take care of this for this concern.
http://wiki.openstreetmap.org/wiki/Proposed_features/Power_generation_refinement
Power generator only regard any kind of device which convert energy from one
sort to another. It should be mapped with power=generator
http://wiki.openstreetmap.org/wiki/Tag:power%3Dgenerator
Power plant is the whole site and can be mapped with an area or a relation if
the power plant isn't enclosed with a fence (which is often the case for hydro
power plant).
power=plant is the tag currently approved.
http://wiki.openstreetmap.org/wiki/Tag:power%3Dplant
The hydropower_project tag may be redundant with power=plant.
Currently, it may be useful to map power=plant sites features only. Generators
are supplementary information only used by specialized mappers.
It would be great to don't use any other custom power=* value to allow the
largest amount of mapper to work with these datas.
I'll add some in my spare time.
All the best
François Lacombe

Fyi, user GautamPratik already started entering some hydro sites using the tag
hydropower_project:name. Here's a search for that:
http://overpass-turbo.eu/s/9lJ
And one for power=generator generally in Nepal: http://overpass-turbo.eu/s/9lN
Cheers, Brad

The Nepal Electric Authority would likely already have such a map, or relevant
data:http://www.nea.org.np/
Page 106 of their annual plan has a transmission line

I did not find anything better in a quick search of their web site, but they
could probably provide something.

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