Re: [HOT] Activation. floods in Peru

[Daniel O'Connor]

One possible thing that is a little different to some past activations is
the availability of gps data via improve-osm.org - it might be worth
checking that against flood affected areas to see if it highlights missing
roads well.

Additionally, strava's GPS 'slide' tool built into ID may allow some
fast/accurate tracing of any missing roads/cloudy imagery.

For example:
http://strava.github.io/iD/#background=Bing&map=16.23/-77.23724/-11.13873&overlays=
,

Obviously neither is going to be 'complete', but may be helpful to quickly
target areas to map.

Those 1600 are some very specific errors I am currently looking at, but
only have those on my local machine currently. But for the wider picture
you can use the OSM Inspectors "area" view to see the scope of the problem.

Just go to any place where HOT/MM was active. Here is an example:
http://tools.geofabrik.de/ osmi/?view=areas&lon=33.65927& lat=-2.07600&zoom=8

My current workflow is as follows: I choose one particular well-defined
problem and extract the data from OSM that shows this problem. Then I
put the data into Maproulette and document the problem and how to fix
it. Some problems are easier, some harder to fix. Mappers can choose
what problems to work on based on their skill level. If somebody
doesn't feel comfortable with one of the harder problems, there are
simpler ones they can work on. I also have some more general
descriptions for the experts who want to go exploring/fixing on their
own. Once the challenges are done, I choose a new problem and start the
process from the beginning.

Here are the current challenges: http://area.jochentopf.com/ fixing.html

Usually I am splitting up larger challenges into regions, for instance
by continent or country. I could also do this by HOT activation area or
so if that makes sense for HOT mappers. Splitting up, often makes the
problems easier to fix, because problems inside an area are often very
similar, but different to problems in other areas due to mapping
priorities and methods. For instance, some regions have lots of problems
with buildings, others with landuse areas, etc. Concentrating on one
very well-defined problem at a time makes all this work simpler.

Hi!
In Peru we are experiencing a difficult time due to the impact

Re: [HOT] Broken (multi)polygon cleanup

[john whelan]

This is similar to my pulling in Africa a country at a time and using JOSM
to check for errors.

What I have noticed is one mapper will misstag then others will follow.  So
sanitising the area or checking it for errors before the new HOT mappers
start would probably improve the overall data quality as they tend to
follow what is already mapped.

Untagged ways by one mapper tend to cluster.  I've seen a 100 buildings in
one small area by the same mapper left as area=yes.  That's quick and easy
to fix.

Recently I came across 42 highways left untagged by the same mapper in the
same area.  The mapper had more than 2,000 edits so wasn't inexperienced.

Crossing highways often I'll see a town where the highway residentials are
laid out in a grid but the junctions aren't nodes.

Another nice recent one was a batch of settlements that had been tagged
highway=unclassified rather than landuse=residential.  Searching for
highways above unclassified and crossing ways picked those out quite
quickly.

These types of errors are handled more quickly directly in JOSM than
involving maproulette.

Even the some other errors can be loaded up in the JOSM  to-do plugin.

I've been cleaning up in Nigeria for a while now.  Making repeated passes
over the same areas over time.  I'm seeing fewer errors so my suspicion is
the improved learnOSM, tutorials and simplifying what we ask mappers to map
is paying off.  Validating new mappers work within 48 hours does pay off in
data quality terms.  Giving feedback more than two weeks later is usually a
waste of time based on my own experience and Martin's report but I don't
think we have the validators to do the validation within the magic 24/48
hours.

Broken multipolyons do take a level of expertise to resolve.  I usually
avoid them.  However new mappers will fearlessly tread ahead and it is to
be expected they will break some.

I don't think learnOSM goes into detail about them or about relationships.
Should they?  That's another question.

For some errors we need boots on the ground.  Especially when it comes to
urban areas with limited access highways such as dual carriageways​ and a
highway approaching them can you turn in either direction?

Often the most motivated people to fix the errors are the locals who will
be using the map.  Trouble is we first have to get something in place that
is useful to get them motivated.

So yes HOT maperthons do have a reputation of the blind leading the blind,
ie some are led by inexperienced mappers but we are putting effort into
reducing the number of errors.  The training group has put together a very
good detailed set of instructions on how best to run a maperthon and if you
can identify a problem area HOT will listen and try to address the issues.

Hi!
In Peru we are experiencing a difficult time due to the impact
that is causing the floods in the country, especially in the
north. This is why we want to open a task in the Task Manager to
call people to the mapping of areas near Piura.

It would be the first time we have activated an alert of this type
here, Humberto Yances has offered to collaborate with us, so here
goes the thanks and the invitation to other collaborators.

Those who have experience mapping flood events, please also share
their insights, tips or recommendations on how we could get
started and how best to collaborate from the map.

We are looking for contact with the respective authorities here,
we hope to get their attention at some point.

Regards!
