Re: [HOT] QGIS and OSM and..

[Springfield Harrison]

Hello Brad,
Thanks
very much for those references, sorry for the slow reply.  The gist
of it seems to be that anything derived from Google Earth images inherits
the copyright.  This seems like a bit of a stretch, but I guess
that's what it is.
But what
if those derived files are not loaded into OSM?  If the helipad
database that I was working on was not distributed through OSM, but
directly to the end-users, then that might avoid the problem?

It seems a bit
murky but thanks for the references, Cheers . . . . . . . . Spring

[HOT] Fwd: Question on Task #1043 roads

[Megha Shrestha]

Hello,

You can tag the unpaved, but maintained roads between small villages as
highway = tertiary. You can see the description in
http://wiki.openstreetmap.org/wiki/Nepal/Roads

Thanks,
Megha





He, all,

I read the instructions for tagging roads on Task

#1043.

However, there is no tag for roads that fall between
highway=secondary
and highway=track. What about the unpaved, but maintained roads between
small
villages? These are roads that we might tag highway=unclassified in the U.S.
These roads often are (barely) two lanes. They're definitely larger than a
typical
track.
Do we tag those highway=secondary also?

Re: [HOT] Idle thought time drones

[john whelan]

HOT already has some experience of drones in Haiti using volunteers.  If we
can grab the images from them then I'm sure they can be processed in a
similar way to the way they are being done in Haiti, we just need to work
out what to do with the data.  The sensors I strongly suspect just use a
different part of the electromagnetic frequency, infra-red / UV for example.

Crowdsourcing bit is more map the outline of the fields and give some of
the programmers and GIS people something to play with.  Initially if we can
get 20% of the gains for 1% of the cost of a commercial system then I think
its doable and we can build on that.  If it works then there will be a lot
of people very interested in mapping their bit of the world in OSM to get
the benefits.

I just float ideas sometimes.

[HOT] Save the Date(s): HOT Community Meetings & Note from HOT Interim Executive Director

[Tyler Radford]

*Meeting 1:* Tuesday 19 May 15:30 UTC

via
IRC (chat) https://kiwiirc.com/client/irc.oftc.net/hot
*Meeting 2:* Wednesday, 20 May 13:00 UTC

[Look
for meeting details early next week]

Dear HOT Community,

Over the past two and a half weeks, you have made an incredible difference
in Nepal. By many measures, the HOT community response has arguably been
larger than any in the past -- averaging close to 1 million map edits and
1000 contributors *per day* in the first 10 days. I personally feel very
proud, and also humble, to be surrounded by such an intelligent and
committed team supported by dedicated partners.

I'd like to invite you to participate in a series of community meetings
next week. The meetings will serve as dedicated time to answer questions
you may have for me or for HOT in general. The past two and half weeks have
not been without challenges, and by coming together, we can discuss ways to
overcome these challenges and improve the services we provide.

As we proceed with our work in the weeks ahead, we should continue to be
guided by our core humanitarian mission: to serve as a bridge between the
OpenStreetMap community and humanitarian responders on the ground. Our role
is one of service, and through this service we have the very real ability
to contribute to saving and improving the lives of disaster survivors. My
role is also service to you - to help enable you to more effectively carry
out this mission. Kindly join us next week for either meeting, and I look
forward to talking with you then.

With warm regards,

[HOT] A letter from Nepal

[Suzan Reed]

I thought mappers may wish to hear a personal account of the first earthquake 
from people living there. S
___

Namaste, this message is from our friend, Andrea, who lives on Mañjushri Hill 
adjacent to Swayambhu. She has lived in Swayambhu for about 40 years, as we 
have. It's a good letter, and I want to share it with you. 
Love & Pranams, Billy

Begin forwarded message:

Namaste to all!

First of all I would like everyone to know that I am fine…even after having 
experienced such a traumatic day/s I know I'm very fortunate!  Hswaaving heard 
about natural disasters in different parts of the world for years; earthquakes, 
floods, avalanches, I now have had the karma to experience such a calamity 
myself…it sure has emphasized how helpless we are…it is mother nature who is in 
charge.  Since January the weather has been strange here, more rains at this 
time of year than I can ever remember…and, they have not been typical rains.  
Often the skies would darken rather threateningly, the thunder and lighten at 
times shaking the earth and the houses, bringing fear to the heart.  

Saturday afternoon, April 25th, around noon, I was sitting in my house reciting 
prayers and the praises to the 21 Taras, the goddess of protection, of 
liberation, the remover of obstacles…as I started the last recitation of the 
praises, trying to visualize each of her aspects, my house started to shake…at 
first I wasn't alarmed as for years we have had tremors from time to time…but, 
just for a few seconds.  This was not the same type of earthquake I've known in 
the past…the whole house started to shake more quickly and violently…suddenly 
it was completely shaking and rattling with a strange sound filling the 
room…instantaneously I realized I had to get out of the house as quickly as 
possible, otherwise it might fall on top of me.  Up I jumped from my bed/ my 
seat where I pray and mediate, and leapt down my steps running into the 
courtyard I grabbed the pole of one of the corner prayer flags…as it swayed 
back and forth violently, at the top of my lungs I was shouting the mantra of 
Arya Tara…Om Tare Tutare Ture Soha…and watching the old house across the 
courtyard crash to the ground…dust and bricks flying, then the dilapidated 
house next to me also started to fall…so I ran to the middle of the courtyard.  
Only the center of this house came down, so what remains is very fragile.  At 
the moment I am fortunate it did not completely collapse because if it had like 
the other across the way, it would have pulled mine partially along with it.   
All living in the area, we gathered on the platform where our water tank is, on 
the side of the hill…everyone huddled together…I continued to pray to Tara.  
After shocks continued throughout the day…there is a pole on top of the 
monastery which we kept looking at, it would immediately begin to swing when 
another tremor began.  Hearing of the conditions of all the houses and the 
monastery...we realized we could not stay inside our houses that night…so we 
began to set up an outside camp.  A plastic tarp was put up…there was a large 
piece of plywood to make as a base for some of us to sleep on and mats for 
others.  After things seemed to be settling down I went into my house, which 
amazingly was still standing and in quite good shape, considering the 
situation, however not in good enough condition live in.  Hopefully with a bit 
of repair…if there are no more large shakes from the center of the earth…we can 
keep our things there, sit in it during the day and set up our kitchen…of 
course this can only happen after all the aftershocks stop.  The stove and gas 
tank, dishes, what ever food and supplies we had were brought out so we could 
cook our meals beside us.  Saturday was a long day…the skies were very cloudy 
and it looked like it was going to rain the whole day…fortunately it 
didn't…giving those who survived time to get something together with others in 
the area where they live.  We heard on the news it was a 7.9 richter 
earthquake…not as strong as the one in 1930…but large enough to do a lot of 
damage…and many more people.  Around five I went on my scooter around the 
bottom of Swayambhu to see what the area looked like…in general it didn't look 
'too bad'…unfortunately there were some tragedies in the area…almost everyone 
was leaving their houses and starting to make camps in open areas.  I stopped 
in to see my Nepali son Bachhu Ram and his family…he works for the Umbrella 
foundation.  This foundation has raised children from poor families, only one 
parent, those who had been miss-placed during the insurgent period, etc… The 
family and all the boys were fine and had already set up a tent outside in a 
safe area next to their house.  It looks as though nothing had cracked or was 
wrong with their house, so as soon as the aftershocks stop they thought they 
would move back in…a foreign seismologist has just advised them to stay outside

Re: [HOT] Idle thought time drones

[Springfield Harrison]

Good thoughts John,

This is well underway with much hardware and software having been
developed.  As with everything, it has challenges.  Googling should turn up
tons of info on presion agriculture and crop health.

The cameras, drones and image processing require fairly high technical
knowledge, not likely a crowd activity.

Drones have many other uses and may be useful for reckon/mapping in the
Nepal disaster.  They might be useful to augment helicopter reconnaissance
and as a local eye in the sky for ground teams.   I have a back pack drone
with an HD camera which can do local inspections for about 20 min. per
battery.  Very good for inaccessible areas.

Drones will be our friends unless misuse brings an early demise.

John, 

I read an article in the past few days by a company that does just that in 
disaster areas. They also ask for volunteers to deploy to disasters with their 
drones. I'll see if I can't find the company and the article.

Re: [HOT] How to fully cover a grid square.

[Suzan Reed]

Pat, 

I would find useful: 
A grid that doesn't change gps coordinates as I change zoom levels (50ft, 
150ft, 300ft, 500ft). 
Something that can be easily turned on and off (keyboard shortcut?)
Lines one pixel wide, very subtle, in a contrasting color, possibly magenta 
(#FF00FF)). 
Numbers on one edge alphabet on the other. 
similar the printed maps in my car. 
in BoldFace Helvetica or Verdana 13 to 15 pt.
in color making it easy to find an exact place. 
Nothing too fancy. 
In both ID and JSOM. 
Hope this suggestion helps.

Some while back, I suggested writing a JOSM plugin to help make sure one has

work in a subtask, they mark it as done and step to the next (e.g. using the 
normal navigation keys).  The user could move out of the subtask without 
marking the task as finished if they want to chase a long feature, then snap 
back to where the subtask they were working on.

I got sidetracked onto other projects.  One of those will end in two weeks, so 
there might be a window there,.  Is anyone interested in collaborating on this? 
 I've worked on Java desktop applications that involve graphics and drawing 
(for telemedicine and digitization of ultrasound images), but have not done 
more than peek at JOSM.  The collaboration might just mean nudzing me about it, 
but if you've worked on a JOSM plugin (hi, Andrew), this would be a good cause.

[HOT] Missing Maps #993 (Unity State, South Sudan): Concern about primary road (Wun_Chuei-Boyapak)

[m902]

Hi,

Is there anyone (perhaps from MSF) with local knowledge of the road 
network in Unity State?
Can you take a look at 
http://www.openstreetmap.org/way/22259826#map=13/8.3387/30.0187 which 
shows the primary road.
In many places I can't see any evidence for it on the ground (on either 
Bing or Mapbox imagery), and even where I can see something it looks 
more like a track than a primary highway. In places, tracks have been 
entered close to the line of this primary road. Possibly these are the 
actual road.


I found a map of Unity State at 
http://reliefweb.int/sites/reliefweb.int/files/resources/map_2691.pdf 
which shows a major road heading west from Leer, but also shows Boyapak 
to be north of Leer. (Neither Boyapak nor Wun Chuei appear on OSM).


This primary road was originally entered in 2008 with a given source of 
UN JLC, so perhaps it was copied from a map such as the one I referred 
to above.


Keen to get this right. Should I delete what is there if there is no 
evidence on the ground? Even though it appears that such a road does exist.


Any advice as to how to proceed?

Thanks
Martin

Further to my previous . . .

Due to the high relief in the risk area, high off-nadir angle imagery may

On the other hand, are there other choices?

Re: [HOT] HOT: Glacial & landslide dammed lakes

[Springfield Harrison]

Hello Steve, Sam,

This is a great headsup and offer from Mr Inglis.

There are likely some people with the required air photo skills available
if they can be found and organized.  They would likely prefer to work in
the GIS that they are familiar with and return a list of high risk targets.

They would need fresh imagery with the risk area defined and probably
gridded into working tiles.   A hands on coordinator/facilitator is
essential to champion this.

Another long shot might be image analysis.  Again, there are likely
specialists in guiding GIS to perform change detection. As the changes are
gross in scale (steep land/rock/river to lake surface), setting up the
differenciation parameters might not be too difficult.   If this succeded,
it could "quickly" generate a list of targets for human assessment.
Timeliness is critical if these unstable lakes are now filling.

Cheers . . . . .   Spring Harrison

Re: [HOT] HOT: Glacial & landslide dammed lakes

[Sam Inglis]

Dear Steve,

I worked for Professor John Reynolds, the man who led the research which
revealed the instability of the dam at Tsho Rolpa. I have read about the
site extensively in his company archives, which was conducting research
there from at least 1998, to present I believe.

He is convinced that Tsho Rolpa is the far more dangerous of the two
majorly dangerous glacial lakes in Nepal, the other being Imja. I would
certainly encourage a very close examination of the region - in particular
there is an ice-core, which has been melting for some time, in the terminal
entraining moraine dam - if I remember correctly, it is at the southern end
(the terminus), under the northwestern section of the dam. If there is any
sign of water seeping from the dam itself, or any slumping in that
section...I would recommend some very drastic and rapid movements to get
people moving from downstream.

Any destabilisation of surrounding slopes, or cracking of the glacier snout
are other things to look out for.

I have loaded one of his many papers on the region, "*Glacial hazard
assessment at Tsho Rolpa, Rolwaling, Central Nepa*l", into my Google Drive
folder for your reference (
https://drive.google.com/folderview?id=0B3qRfjnIhqMhfm44dlZnM2x3Um1ia09mV2FwNHhLQmR2TDZKNVBaNFlyNENERkNZTkNmOU0&usp=sharing
).

​There are a large number of papers assessing the potential, identifying
what to look for, etc.

If you have specific questions, I'm always happy to help and, as suggested
before, would consider throwing together a quick handbook to help with
identification of the key risks.​

​Thanks,​

 Hi Sam,

 I think honestly you’re better placed to tell us how you can help than
 the other way around. Most of us aren’t glacial lake experts :-)

 My first thought is that you can trace lakes in the affected areas into
 OSM. The second would be to help us understand what, if any, risks can
 result from lakes being dammed by landslides.

Re: [HOT] HOT: Glacial & landslide dammed lakes

[Steve Bower]

Tsho Rolpa, northern Dolakha district, is another glacial lake renowned for
having an unstable natural dam, putting thousands at risk downstream.

http://www.bigmaybe.com/learn?s=Tsho_Rolpa

Perhaps there is an existing assessment of natural dams at risk of failing.

 Dear HOT Team,

 My name is Sam Inglis, and my background is in glacial lake detection,
 identification and mapping, and was the first person to identify all
 glacial lakes in the North Patagonian Icefield, Chile. I am familiar with
 Himalayan mountain ranges, and studied large swathes of the Indo-Tibetan
 catchment of the Sutlej River, which runs from near Mt Kailash, transects
 Himachal Pradesh, and terminates in Pakistani territory.

 I have previously not engaged much in communal, open-source, reactive
 disaster mapping, but have been adding to the OSM database in Nepal
 sporadically over the past two weeks, when time has permitted.

 Yesterday, I saw that NASA had posted an article
 
 on the formation of landslide-dammed lakes along Nepal's rivers, near
 Gorkha, and was wondering how I can best contribute to enhancing the
 understanding of the features? How can I help with such hazard detection &
 analysis?

 Thanks, and I look forward to hearing back from you and the team!

 Keep up the great work!

 Sam Inglis MSc

Thanks Sam for the link!
As you can see in the article, we the Kathmandu Living Labs have been
working closely with the Himalayan disaster volunteer group / yellow house
volunteers via our Quakemap.org platform.

We could perhaps increase collaborations around use and contributions to
OpenStreetMap data, we can follow up with that in the days to come. Thanks
for the pointer!

Re: [HOT] HOT: Glacial & landslide dammed lakes

[Sam Inglis]

Dear All,

I agree totally, the hydropower issues are enormous - a very important case
study of the 1985 Dig Tsho glacial lake disaster, studied by Vuichard &
Zimmerman in 1987, revealed the destructive potential of Glacial Lake
Outburst Floods (GLOFs) and LLOFs.

Please see via:
https://drive.google.com/open?id=0B3qRfjnIhqMhfm44dlZnM2x3Um1ia09mV2FwNHhLQmR2TDZKNVBaNFlyNENERkNZTkNmOU0&authuser=0

I would be happy to scan the satellite imagery for viable sites, but the
main issue is LLOFs (Landslide-dammed Lake Outburst Floods) in the
immediate future. In order to identify these, the HOT team needs to make
current satellite imagery available (my apologies if this has already been
done).

I am also quite busy at the moment, and very sadly (selfishly) cannot
commit to mapping the situation in the next day or so. However, the key
things to be looking out for are* landslide-dammed lakes*. They are highly
destructive, enormously unstable, filled by glacial melt waters, debris,
rainwater, and anything else entrained by the waters, and very deadly.

These features form very rapidly - a 6km lake formed and burst within a
couple of days along the Sutlej River, due to a combination of internal
pressure (the river has a naturally high discharge rate), compounded by a
cloudburst.

Also keep an eye out for shifting glaciers, as their migrations will
release sub- or englacial (internal) meltwater - the slipping of glaciers
down valley may have blocked sections of rivers, and would create very
dangerous situations.

I could try and come up with a brief handbook on what to look out for, so
that the features can be identified, in the next 4 days? If this agreeable,
someone should just give me an idea of what the team needs, and I'll work
to spec!

Thanks,

Sam Inglis MSc

[HOT] Nepal’s Aid System Is Broken. So These Lifesavers Hacked It

[Sam B]

Friends- looks like your efforts can use the information collected by this
Yellow House group:
http://www.wired.com/2015/05/nepal-earthquake-aid/

One week later, someone showed up: a raft guide named Megh Ale, who
operates an eco-resort on the Bhote Koshi. He arrived with some medical
supplies, volunteers, and not enough food. Upon seeing the extent of the
devastation, he approached the Deujas. Ale told the cousins to head to
Kathmandu and find a bed-and-breakfast called the Yellow House. Over the
past two weeks, as the government and large international NGOs have
struggled to deliver supplies in Nepal’s remote regions, the Yellow House
has emerged as the hub of a vibrant guerrilla aid operation run by a
handful of young people armed with little more than Facebook, open source
mapping technology, local knowledge, and some antiestablishment verve.

Unregistered, unlicensed, and nonexistent in official terms, the Yellow
House group is one of many ad hoc efforts that have cropped up to deliver
aid to some of the quake’s hardest-hit areas quickly and without much fuss.
Recently, the milieu at the Yellow House has expanded from urbane young
Nepalis and wide-eyed international travelers to include prominent NGOs
such as Team Rubicon, a group of US military vets sponsored by the Home
Depot. Even the United Nations High Commissioner for Refugees (UNHCR) has
started delivering supplies through the group. But Sandesh and Dipak didn’t
know any of that, nor would they have particularly cared. They just needed
some rice and tarps, given the forthcoming monsoons. So they recruited two
of the town’s other young, strong men. Then they started walking down the

Re: [HOT] How to fully cover a grid square.

[Blake Girardot]

I have been looking for something like an adjustable grid for a while.

Adjustable because sometimes I am doing scanning at different zoom 
levels depending on the features I am looking for.


Java is the one language I just never even got a toe hold on, I can 
barely get the development stack going.


Thank you for thinking about it.

Cheers,
Blake

to split the task into a grid with cells (subtasks) just slightly

satisfied with their work in a subtask, they mark it as done and step to
the next (e.g. using the normal navigation keys).  The user could move
out of the subtask without marking the task as finished if they want to
chase a long feature, then snap back to where the subtask they were
working on.

I got sidetracked onto other projects.  One of those will end in two
weeks, so there might be a window there,.  Is anyone interested in
collaborating on this?  I've worked on Java desktop applications that
involve graphics and drawing (for telemedicine and digitization of
ultrasound images), but have not done more than peek at JOSM.  The
collaboration might just mean nudzing me about it, but if you've worked
on a JOSM plugin (hi, Andrew), this would be a good cause.  ;-)

Re: [HOT] HOT: Glacial & landslide dammed lakes

[Steve]

From the open street map some buildings are missing to what is shown on the 
current google maps image .
How up to date is the open street map ?
Are we supposed to be highlighting on open street possible houses that have 
been damaged ? 
Or just current buildings we can see on open street ? 
Kind regards
Steve

Re: [HOT] Nepal recap

[Nirab Pudasaini]

Also please take a look at
http://tasks.hotosm.org/project/1043

We will need more help as Ministry of Home Affairs press release yesterday
extended the effected district to 32 districts. 17 districts are currently
well mapped. There are tasks for 3 new. We are working on finding out where
we need maps and then start working on creating new tasks.

Thank you all the Mappers for their help.

Dear Sam,

Thanks for proposing your expertise and help.

I am adding the Activation Working Group and a list of people (Bcc)
that are working on landslide risk assesment.

My hope is that between experts you will be able to come up with great
value other than plain mapping.

Yes, 1018 is still ongoing, new ones are certainly 1047 & 1048.
