Re: [HOT] New mapper needs some feedback :-)

[Robert Banick]

Hi Martin,

I didn’t have time to review your work, but just wanted to add: don’t
despair if you complete some tiles and they aren’t promptly validated! HOT
has grown a lot in the past year or so and we have a lot more mappers than
validators as a result. So sometimes it can take a little time to get a
response. Posting to the listserv like you did is a great way to call
attention to tiles that need a second look. Welcome to OSM and keep on
mapping!

Re: [HOT] New mapper needs some feedback :-)

Hi Martin,

If you get serious about mapping, don't postpone the 'upgrade' to JOSM.

I'm creating some screencasts on Twitch. Unfortunately they are not very
organised or structured yet: I'm still in the process of trying to figure
out what works and what doesn't for these screencasts.

http://www.twitch.tv/polyglot_openstreetmap/profile/highlights

The latest ones go into the import of schools and how to create wikidata
items on the fly. Let's call that a somewhat more advanced topic. The ones
you want to look at were made in December and January. Unfortunately most
of them didn't have sound back then. Still trying to build up confidence to
talk in English (and agility to concentrate on simultaneously talk and
map...)

Cheers,

Polyglot

Re: [HOT] New mapper needs some feedback :-)

[Shawn Day]

Well done Martin. I just took a quick look at tile 371. It is well mapped and 
you did a very fine job. There are a few things I corrected in validating. 1. 
In a couple cases when you squared the buildings, they grew in size (as they
do and most were well squared) and needed to be slightly reduced in size to
match the underlying imagery. 2. In a few cases the building encompassed the 
walled yard - the imagery is
soft and light so easily done. Reduced the area to the building. 3. In a few 
cases, there were overlaps between buildings - again suspect that
in the squaring function, the revised shape grew and caused the overlap - there
was an overlap or two between roadways (well defined btw) buildings. 4. And as 
we all have a few errant buildings that somehow escaped the squaring
function. Overall, a well done tile and well done by you. Keep on mapping.

Hi all,

You might remember Felix's email from a few weeks ago about the
project he and local mappers in Managua self-organized to
map the
city's 380 km of bus routes.

It is really an amazing story and accomplishment and will
make a big
difference in the lives of well over 1 million people who
depend on
the public transit system in Managua and never had a map of
routes or
stops before now.

He wrote up a blog post for HOT about it:


https://hotosm.org/updates/2016-01-07_a_crowd_sourced_public_transportation_map_for_managua

And as you may or may not remember, now that they have the
routes and
stops fully mapped, they need to design a printed transit
map and
produce an initial run of 20,000 copies so the people of
the city can
really benefit.

76% of the population of Nicaragua lives on less than USD
$2.00 per
day, the only chance most of them will have to make use of
this new
transit system map is if it is printed and distributed in
the city and
on the buses.

Felix and HOT are running a donation site to fund the
design and
production of the printed maps with a goal of raising
$7,500 for the
initial 20,000 print run.

This is a great chance to directly affect the lives of over
a million
people in a way that no one has been able to accomplish in
years of
trying (see the blog post). OSM Nicaragua did it on their
own, 

[HOT] Likasi, Katanga, DRC - tasking and field mapping

[Pete Masters]

Hi all, hope you are well

I have just arrived back from Lubumbashi in Katanga, DRC where we delivered
training on data collection, base mapping and basic GIS (inc. Missing Maps,
HOT and OSM).

The MSF team had just finished supporting a Ministry of Health cholera
intervention in Likasi in December / January. They said that had Likasi
been mapped, they would have much better been able to do spatial analysis
of the disease spread and incidence (case rate per 1000).

It just so happens that the OSM guys at Lubumbashi university (the same
guys that worked with Ivan, Jorieke and Claire to do the beautiful mapping
of Lubumbashi itself [1
]) are in
Likasi right now doing field mapping.

As it is likely that this will not be MSF's last visit to Likasi, we'd like
to support the Lubum guys with remote mapping, so I just wanted to give a
heads up on task 1460 [2 ].

It's great for beginners - mostly buildings and some residential roads -
and the imagery is clear.

If you have any questions, please feel free...

Cheers,

Pete

Hello from Doha!

This article from opensource.com is great because it shares about how else
people can support the mission. The good news is that HOT is has some of
these activities in place.

Https://opensource.com/life/16/1/8-ways-contribute-open-source-without-writing-code

I have often felt we need a task manager for other community activities,
but right now those are documented on the various trello boards. Until
then, Here is how to Get involved:

I've been playing around with Serval software on Android. Ideally
it needs a wifi mesh set up using multiple firmware modified
TP-Link MR3020 portable routers with custom software connected to
a small radio device which turns it into a mesh extender.

The original concept was to turn the smartphone into a router but
the latest Android software well anything above 2.2 denies access
to do this.  Besides which rooting the phone in this manner is not
good from the security point of view.

However if you are running Windows 10 and your Laptop supports it,
most should, you can turn your laptop into a wifi hot spot that
other devices can connect to. Note you should not need to be
connected to the Internet for this to work.

Translation Android smartphones running Serval within say 100
meters of the laptop  can now talk to each other.  I haven't tried
a phone call, I don't have two Smartphones to hand, but messaging
certainly works.

You should also be able to transfer files certainly from one
smartphone to another and if Serval doesn't support file transfer
to the host laptop there are other apps around that do.  So things
like the latest maps for Osmand etc can be brought down once to
the laptop then propagated out to smartphones or a smartphone sent
by mail, mule etc to the wifi hub can then connect and distribute
files etc.

I haven't looked at the implications of interconnecting laptops
perhaps with cat 5 cables and although phone calls should be fine
across one wifi hub theoretically each hub used in the hops adds a
small delay so voice quality over multiple hops may not be ideal.

[HOT] MSF UK looking for help with app development...

[Pete Masters]

Hi all, I think this is approprate for this list. Please let me know if
not...

As part of Missing Maps, MSF UK is developing a new micro-mapping app for
smartphones. This is a step on from the Pybossa tasks that Disastermappers
at Heidelberg Uni developed for helping us search large areas remotely to
find roads, settlements, etc [1

].

The dev team are looking for some help from:

"android or ios devs, ideally with a bit of tilemill or geo apps
experience, or gaming experience (even better)"

This is primarily a volunteer opportunity, but may there be short term paid
opportunities that come out of it.

If you are interested, or know anyone that is, please get in touch at
missing.m...@london.msf.org

The app will allow users to classify imagery tiles and help HOT Tasking
Manager project creators to discard areas with no features and make tasks
that are a more efficient use of mappers' time.

Cheers,

Pete

Re: [HOT] landuse/cover import in Cameroon?

[Willy Franck Sob]

Bonjour  à toutes et à tous,

Tout d'abord recevez nos meilleurs vœux pour cette nouvelle année qui
commence.

Je viens de prendre connaissance de vos échanges au sujet de l'import
massif de l'occupation du sol sur une partie de l'ouest Cameroun:
http://wiki.openstreetmap.org/wiki/Bad_imports/Cameroun_Ouest_region_landuse_import

En effet il s'agit d'un contributeur que j'ai identifié qui dans le carte
d'un projet de cartographie à jugé bon d'importer directement dans OSM les
données issues d'une classification (télédétection). Mais comme le disait
Sander Deryckere, les données sont horribles.


J'ai pris rendez-vous cet après-midi avec le contributeur, nous avons
convenu de supprimer et de mieux structurer les données avant l'import dans
OSM en respectant un certains nombre de canaux.

En pièce jointe les Id des changesets correspondant, j'ai tenté de faire un
revert depuis la BD OSM en suivant ce lien :
http://wiki.openstreetmap.org/wiki/Revert_scripts

Mais malheureusement les données sont toujours en ligne... je propose que
les données soient supprimées...



Willy

..

Hello everyone,

Firstly receive our best wishes for this new year.

About the import of massive land occupation on a part of western Cameroo
http://wiki.openstreetmap.org/wiki/Bad_imports/Cameroun_Ouest_region_landuse_import

He is a contributor I identified who wished to import directly into OSM
data from satellite imagery.But as Sander Deryckere said, it is horrible.

I made an appointment this afternoon with the contributor, we agreed to
remove and to better structure the data before import to OSM respecting a
certain number of channels.


In the attachment the changesets-ID corresponding , I tried to do a revert from
the OSM database by following this link :
http://wiki.openstreetmap.org/wiki/Revert_scripts

But unfortunately the data is still on OSM... can someone do it properly?

[HOT] Mapping stories from the field in Uganda

[Paul Uithol]

Good evening from Uganda! After spending three weeks in Mbale and 
mapping 11 districts there, we've now moved on to Tororo, another town 
in the east, close to the Kenyan border.


One of the students we've worked with from UCU Mbale, Hillary Musundi, 
has written an amazing story on his experiences mapping with us. Please 
read the full story at

Re: [HOT] Smartphones using wifi in the field If you ain't in the field or techie ignore this post.

[Mhairi O'Hara]

Cheers John! We're collecting data on financial services, education and
health facilities in Eastern Uganda and are looking for sharing solutions
that don't involve the internet. With up to 50 students at times, sharing
files via usb sticks and external hard drives is not ideal as it can be
time consuming. Will look into the setup to see if it could work for us
here.

Hey everyone,

Thank you everyone for the kind words and encouragement. I will keep your tips 
in mind, continue to map and start to learn how to use JOSM.

Re: [HOT] Smartphones using wifi in the field If you ain't in the field or techie ignore this post.

[john whelan]

It also works on an ASUS RT-N66U which is a conventional wifi router but
has greater range than a lap top hot spot or smartphone.  If it works on
that it should work on anything as a single hub.  It's only if you want to
mesh them that it gets more complicated.

Re: [HOT] Smartphones using wifi in the field If you ain't in the field or techie ignore this post.

[john whelan]

With fifty users sharing files you probaly want to use a couple of linked
hubs, that's where the TP-LINK MR3020 starts to shine.  I have one here and
one waiting to be picked up at the computer store to test but its freezing
rain here in Ottawa at the moment so there is a layer of ice on the
sidewalk, not so good for walking on.  However you can use two laptops
independantly and collate the files later on.

If you are texting only then one hub should be enough for fifty users, for
voice calls depending on the traffic it should just work since not everyone
will be using it at the same time.  For file transfer, depending on the
size of the files you might want to split the load over more than one hub.

For voice over more than one hub you need to link them so you need two or
more TP-Link devices with the special firmware.  Linked in this way you can
send a text to a device that is not available and in theory it will be
delivered when it comes in range next.

>From a practical point of view Paul's mesh extender combines a hub with a
small radio so you can link over longer distances.  It uses the same
frequency as a car garage opener to build the mesh.  It also comes in a
plastic box to keep the weather out.  Unfortunately it's not quite in
product yet but bug New Zealand's Red Cross and they should have some idea
of time frames.

If you're using a TP-LINK MR3020 it does require a power source, but
battery powered USB boxes are around to extend the battery life of a
smartphone.

http://developer.servalproject.org/dokuwiki/doku.php

https://en.wikipedia.org/wiki/Serval_project

It appears you can use any wifi hub that supports peers.  Note this isn't
quite the approach that the Serval team has been using up until now and I'd
need to play with the specific router to get the configuration sorted out
so stay with the specific Tp-link device or the win 10 hot spot and test it
before you go out in the field.

The portable wifi hub the TP-link is cheaper than a laptop, around $40
locally.  If you want to link them up then you need to flash them with a
different firmware.  I haven't done this yet but it is on the to do list
and it should be possible with a laptop but does require running some form
of unix on the laptop but that can be done under windows.  Once it is set
up then it takes a couple of minutes to update the firmware on the hub.
Want me to write up the process on how to configure one for stand alone
use?  Where would you like this written up?  Note different coutries have
slightly different rules for wifi etc. and a standard TP-Link hub
understands these so which country it will be used in is part of the setup
process.  Hopefully the linking firmware takes this into account.

Note there are other solutions than serval for sharing files, especially
using a hot spot from a laptop.  Essentially you can use the laptop as a
web server, in theory you just need the appropiate .html file(s) on the
laptop.  So you can link windows laptops together using this technique you
don't need serval for this.

If you use html5 code and have the downloads as .zips then you should be
able to click on the link and the file will download automatically.  I have
some simple sample html5 code floating around if anyone wants some.  I
think most smartphones can handle .zip files.

The other thing to note is that wifi devices such as Nexus 7 tablets can
use voice to smartphones running Serval.  In general wifi tablets are
cheaper than smartphones.

and you thought the HOT mailing list was just about mapping.

Oh one last thing, there is a difference between a very small network and

Re: [HOT] PetaJakarta

[Steven Johnson]

The next to the last paragraph:

"Resilience is built by communities and agencies before, during and after a
disaster. Resilience includes the work of volunteers, such as those in
northern England who, following recent flooding, organised to clean
streets, clear debris, and distribute aid to those in need."


Well said. The HOT ID team has worked across multiple levels of government,
with universities, and community groups helps extend public services to
where they are in most need. This article does a good job of making the
connection between open mapping and responsive civil institutions. Hard to
overemphasize that point. Congratulations to Team HOT ID.
