Re: [HOT] note to Project Managers: Highway=road

[Pierre Béland]

See comments that I made today for the Matthew disaster 
response.https://lists.openstreetmap.org/pipermail/hot/2017-February/013021.html

This applies also to road tagging. Instructions in the tasking manager are only 
one step to complete the global task of mapping for an area.
 We need a collectiv approach, a systematic revision of road tagging. 
Organisers of mapathonns, and later Project managers, should monitor road 
addition and assure that the tagging is corrected appropriately by experienced 
mappers.
 As John just said, it is important to classify appropriately for the various 
Navigation Applications to find the appropriate roads to connect between two 
points.

Re: [HOT] Matthew

[Pierre Béland]

Hi all,
Mapping for disaster response is to support NGO's and assure a good territory 
management. Mountains in Grand'Anse and Sud department are quite particular 
with people spread everywhere.  Both houses, road and path networks are 
important.
I am just back from the UNOGA - Potentiel 3.0 mission with Fred and others in 
the mountain valley around Despagne, Grand'Anse. People in this 1,000 meter 
altitude valley are spread in the various hills and live for subistance 
agriculture. Walking in the valley, we saw destructed houses everywhere. People 
are still waiting for substantial help 4 months after the hurricane. Nights are 
very cold and humid. Houses, tools, livestock, plants and seeds were lost. 
While the majority of houses are destructed, we saw very few reconstuction or 
roof repairs. So far, NGO's have concentrated their efforts in the more 
accessible areas along the National road.  

We visited many families in the valley.  They used debris from the hurricane to 
build temporary shelters next to their destroyed stone houses. Their situation 
is very precarious. Many health problems are reported and no permanent health 
clinic in the valley except a 1 day/month clinic. It takes three hours by truck 
to go to the clinic in Leon. These families live from subsistence farming. They 
are currently undernourished and the aid received is still too minimal.
Talking about mapping, let's be clear.  Various actions need to be taken to 
assure a good coverage and qualit of data.

We need images clear and detailed enough to spot houses, paths and highways. 
Various images with various quality, dates and offsets were used to cover the 
Matthew huricane disaster area. In this context it was difficult for newcomers 
to interpret the imagery and provide good data.

When we discuss about quality of data, we do not say that this is the 
responsability of newcomers. They need more support and monitoring from the 
organizers of mapathons and the OSM humanitarian community. In 2016, prior to 
the october hurricane, various Mapathons were organized to map Haiti. The 
Disaster response was concentrated in the first 2 weeks of october. But badly, 
not enough efforts to correct the data in these two weeks and since then. Read 
again https://lists.openstreetmap.org/pipermail/hot/2016-November/012673.html

Other then assure the quality of the data for this ungoing disaster response, 
tools should be developped to monitor each Mapathon and support Mapathon 
organizers providing more support and feedback to the newcomers The people that 
organize mapathons should accept the responsability to provide better quality.  

In the past more experienced mappers did contribute to Disaster responses. It 
was then ok to say that others will correct later while the majority of 
contributors where experienced. In the last two years we often discussed about 
the impact to organize mapathons and bring thousand of new contributors to 
participate in a short period of time to mapathons. Read again discussions for 
the Nepal response and the report that I wrote after. 

The Tasking manager simply help to distribute efforts to cover mapping and 
validation of each square.  This need to be completed with Monitoring tools 
that cover a complete area or a particular group contribution. Otherwise OSM 
will loose it's credibility as the de facto Map for disaster response.  We 
cannot accept the answer that other people will come later and correct the data.
Monitoring and Quality tools are important to collectively provide a better OSM 
map to support humanitarian actions and better follow newcomers edit:- live 
tools that can follow the Group activity and spot rapidly the type of problems 
and individual contributors errors. 
- Have tools for Mapathons organizers to report the list of contributors
- Quality data tools that can monitor a specific area would also help to come 
back to a particular area and evaluate what's need to be corrected.
Quality is more important then quantity.  Covering the map with so many errors, 
we discourage the more experience mappers.

[HOT] Leaving my Missing Maps job

[Pete Masters]

Hello all, I hope you are well...

Apologies for using the mailing list to send a personal message, but I feel
like (and hope) it isn't inappropriate.

My time as coordinator for Missing Maps at MSF is coming to an end - last
week I accepted a new position within MSF working on innovation process and
how we better approach field problems and opportunities. I wanted to let
this community know personally for a few different reasons

Firstly, to say thanks for the education. It has been an absolute pleasure
to work with such a varied bunch of dedicated, passionate and clever
people. I have been an MSF fanboy for a long time and I am now a HOT and
OSM fanboy too. My job over the past two and a half years has been to try,
as much as possible, to find the overlaps and opportunities between these
two (very different) organisations and communities. As I hope you have
noticed, I have tried to connect the dots between what the HOT and Missing
Maps community can do for MSF and the impact that that volunteering has on
real people (both our staff in the field and our patients).  What you
probably don't know is that I also evangelise HOT / OSM within MSF - not
just for the mapping, but for the principles of openness and teamwork and
sharing that make mapping and collaborating on such a scale possible.

Secondly, because you should know that what you have accomplished during
this past two and a half years through HOT activations and Missing Maps
projects is pretty unprecedented in MSF. Operational people and medical
people within MSF now *expect* to be able to rely on Missing Maps and HOT
to deliver data for decision making in the places we work. The quality of
your work and the dedication you show (often at very short notice) has
taken the project from a suspiciously viewed, disruptive, unorthodox and
often misunderstood project in MSF into a tool that the people delivering
aid on the ground value and want. That's huge.

Thirdly, I appreciate that there are massive challenges ahead. Discussion
started by Fred on validation is high up that list. As is the scale of the
supply and demand from organisations like MSF. As is how we leverage the
data these organisations are collecting on the ground as part of their
day-to-day to enrich the OSM database (but including how we do that in a
resposible and sustainable way). I have no doubt that together we (I fully
intend to stay a part of the HOT community despite the change in day job)
can address these challenges and whatever comes after. I would like to
offer this opportunity to feed back to me any thoughts you may have on the
future of Missing Maps and MSF or any other feedback you may have.

Lastly, there is going to be a very cool job available at MSF UK. Not an
easy job by any means (the phrase jack of all trades doesn't do it
justice), but a massively fulfilling one. Knowing the talent available
amongst you, I'd strongly encourage you to take a look when the job is
advertised.

That's it really. It's not goodbye by any means and I look forward to
continuing these discussions beyond the end of my MSF Missing Maps job...
Apologies for the lack of brevity!

Cheers,

Pete

Re: [HOT] Matthew

[john whelan]

Data quality is always an issue and we don't have enough validators which
doesn't help.

We also have user expectations.  If you want to use OSM in a particular
area with low internet access perhaps you could arrange with someone to run
an eye over the area first?  With a large number of different mappers
mapping by hand I think you must expect some inconsistences. I've even seen
mappers with more than two years experience tagging in a way that didn't
follow local guidelines.

We know if we catch mappers making mistakes within the first 24 hours the
errors go down after that.  Crisis mapping is always going to be lots of
new people wanting to help.  In Nepal I think 70% of the mappers were first
time mappers and if you think data quality is bad in Haiti then Nepal was
off the scale.

Since the recent changes to the task manager, iD and the training guides I
have seen the number of errors decrease.

What I have noticed is some projects are better managed than others.  I
think a recent one I looked at the bottom 25% of the project had no mapable
imagery from Bing or other sources.  Other African projects have
instructions that do not follow the African highway wiki.  The problem here
is by not presenting a consistent professional image to the mappers it
gives the impression that we don't care, and that this stuff isn't very
important.

Currently validation isn't anyone's responsibility.  Perhaps as part of the
project plan check list the project managers should be asked what plans do
they have to ensure that 50% of new mappers work will be validated within
48 hours or whatever the magic window Martin's work shows and that does not
include asking me to validate yet another project. I have my own
idiosyncrasies about which I validate on and it does take a fair bit of
time and effort to do it right.

I sympathise with the idea of commenting "Just clean up this mess!" but
recognise Blake's comment of pat them on the head and make them feel a
little happier is valid as well.  For the most part we are talking
volunteers so persuasion works best, having said that something very
interesting is taking place in Lusaka.  I'm fairly certain from the mapping
being done that although the mappers are new to OSM they do know GIS and
the quality of mapping is very high.  Project 2543 is an example.  There
has also been some work counting buildings etc using R and the local level
of government seem to be involved.

You will discover that is not possible to use OSM like that due to a number
of duplicate building.

So please include a strong validation or cleaning process after each
activation.

As is not acceptable to work like that and let all this mistake

All the best FredM

Re: [HOT] Matthew

[Donal Hunt]

It's often helpful when these type of things happen to address the
immediate issue (cleaning up) and the process and tooling issues that led
to the duplicates being created in the first place.
It's probably too long since the original effort but if there are actions
that could prevent a repeat occurrence in the future, calling them out
(here?) and ensuring they result in action being taken will help everyone
in the longer run.

e.g. could learning material for volunteers / mapathon leaders highlight
the behaviours that can lead to this situation more clearly? Are there
tooling changes that are needed to spot these during the submit process
(changes may have already been implemented through other efforts)?

Regards

Donal

Re: [HOT] Matthew

[Blake Girardot HOT/OSM]

Dear Fred,

Thank you for the feedback.

It would help if you provided an actual area and not just an generic
link to osmose.

I did review all of NW Haiti for duplicate buildings which is what
seems to be the biggest issue and out of 68,000 buildings over
approximately 1500 sq/km found 470 duplicate buildings. ( graphic
https://screenpresso.com/=2eYrd )

Which is pretty good in my view, less than 0.7% error rate. Still it
would be good to fix them, especially since it is pretty easy to fix.

For an experienced mapper, it should take about 1 hour to fix them all.

I fixed 100 of them in about 15 mins the slow way :)

I would be happy to share my work flow for fixing them if that would
help you at all.

My only other comment is that if you are really interested in getting
the errors corrected, being a bit more understanding and respectful of
the volunteer mapper's efforts might motive people to dive in and
help. Phrases like "clean up your mess" is not a good approach in my
experience. "Hey, I found a lot of duplicate buildings, could we find
a way to get them corrected?" would probably have generated a lot more
volunteers to jump in and help.

Cheers,
Blake

Re: [HOT] Matthew

[Sebastian Langer]

Hi everyone,

I can only confirm that. Although the overall mapping coverage is great,
there absolutely work to be done again on the validation-side.
Duplicate buildings and the topology of the road network are the two
most striking issues, I would say.

All the best,
Sebastian
