Re: [HOT] Asking your help to map in Honduras, Chad and Burundi for MSF

[Vao Matua]

Is anyone else having a problem invalidating tiles today?
The TM keeps throwing errors when I try to invalidate a tile, or tiles.

[HOT] Corporate mapathon?

[Vao Matua]

I am seeing edits in our HOT projects in Tanzania with these hashtags:
#ACNAustraliaFY19
#acnmelbourne
#acnaNZ-june20

Last month we had significant problems with the work associated with these
hashtags.
Does anyone know who they are and the contact information about the leader?

Thanks

[HOT] Edits from India

[Vao Matua]

On a couple of HOT projects in Tanzania there are some edits that did not
follow the task instructions, and actually created some very poor quality.
It appears that the editors are from India and are new editors. Some of the
tags that have been added to the changesets are: #acnglobalmapathonfy19
#AcnIndiaHyderabadFY19, #AcnIndiaMombaiFY19
Most of the edits were done on 20 March 2019

Does anyone have any information about these efforts?
It would be good to help future edits from this group to be a positive
contribution rather than a problem for OSM users.

Re: [HOT] NB: Organised Editing Guidelines | Re: Final Request: Volunteers Needed for Global Mapathons!

[Vao Matua]

Rory,

You are absolutely right, I'm not suggesting not using those guidelines, we
need them. The Organized Editing Guidelines are fine and I believe most of
the people in the OSM community want to follow the guidelines or at least
follow in spirit. I've worked very hard to create good clear instructions
when creating HOT tasks. If a mapathon host or newbie editor would follow
those directions and the Guidelines we wouldn't have the problems we are
seeing.
The challenge I see is: How do we help the semi-informed follow those
guidelines and the task instructions?

Re: [HOT] NB: Organised Editing Guidelines | Re: Final Request: Volunteers Needed for Global Mapathons!

[Vao Matua]

Mikel et al,

I agree that we need to change the way we do mapathons, the credibility of
HOT and OSM is at risk.
I have observed some characteristics about the OSM mapping through HOT
tasks being done by mapathons, primarily ones done by corporate sponsors.
It appears that often these efforts are not well led, or at least not led
by individuals that have a good level of OSM experience and skills. The
results are that very common mistakes and errors are created.
1) The instructions are not followed, nor even apparently read.
2) Individuals assume that a tile must be completely mapped and will add
features that are not called for in the instructions such as landuse or
highways.
3) The tagging of features is not done based on OSM guidance, for example a
path in Tanzania is often tagged as "motorway", "primary", "secondary" or
other type of highway.
4) Additional tags are added without local knowledge such as railroads,
traffic cameras, and businesses that are not apparent from imagery.
5) Using iD with the default image (Bing) without changing the background
image leads people to mark a tile as "bad imagery" when the Digital Globe
or Esri imagery in that location is fine.
6) Sometimes mappers will assume that OSM is a game like Sim City or
Minecraft and create their own imaginary features
7) One characteristic of many of these mappers is an apparent hurried to
try to finish a tile. The buildings are over-generalized by either
combining buildings, creating polygons much larger than the actual
building, often the shapes are very crude and are not carefully formed with
right angles, many buildings are skipped or overlooked, many are
overlapping with other buildings or roads, and in many cases create
self-intersecting polygons
8) Once a mapper starts with these bad habits the habits are picked up by
others working at the same time which expands the problems
9) It appears that after a small number of edit sessions the mappers from
these efforts do not continue with other HOT tasks, and presumably go a way
thinking they have done their feel-good-humanitarian-service.

The net result of these mapathons is that rather than contributing to the
completion of mapping in an area, there is actually more work required to
clean up the messes than there would have been to properly trace the
features from scratch.
I do not believe this is a validation issue, but is an issue with
leadership. The individual organizing the event for the corporation or
group may have little or no OSM experience, and have been giving the task
of setting up the mapathon  and do not have the skills or expertise to help
newbie mappers.  I also have seen people that claim to have OSM experience
or skills often are very inexperienced and have very slight exposure, There
is a lot to learn about OSM, and we do ourselves a disservice by saying
that it's easy and anyone can do it. We should be happy to teach people,
but I don't believe any of us doesn't have more to learn.
I have led several corporate mapathons in person and remotely, they are
hard work. The same can be said for tertiary school effort.

Perhaps HOT should establish a test or a vetting process for potential
mapathon leaders?

Re: [HOT] leisure=common replacement for urban public areas in Africa]

[Vao Matua]

I'm not quite sure why landuse=village_green doesn't meet this need. There
are plenty of examples of British word usage in OSM are not the same as the
original vernacular.
Often in Africa an open area can be quite green in the rainy season and
brown in the dry season.
I'm not opposed to this proposal, but just don't understand the added value.

Re: [HOT] Why the HOT obsession with low quality buildings in Africa ?

When you say "low quality" buildings, do you mean the quality of the
polygon data or are you judging someone's home to be of low value?

Re: [HOT] Highway Tag Africa wiki

[Vao Matua]

Thanks for the comments.
The difference between unclassified versus residential is a challenge for
many people, including myself.
The language in the unclassified is trying to describe the function of
connecting settlements rather than a road where people live.
What is a settlement? Hamlet or larger? A few houses 500 meters away?
This is quite difficult for me in Ethiopia since 90% of the population
lives in a rural setting.
I'm looking for ways to describe what these roads would look like in the
imagery, suggestions?

As far as the 2921 living_streets in Angola that is exactly the type of
thing that could be prevented if that tag value was not available in iD or
JOSM when editing anywhere besides Germany or the Netherlands (or any other
location where that was a legal description).

There was quite a bit of discussion and agreement that the existing tagging
can be frustrating, however, we did not generate any new proposals for
additional tags.
We did agree on some changes to the Africa Highway Tagging Guide
 which has now been
updated to reflect not only Functional Class but also Construction class
and width.
I am in the process of preparing a one page reference guide for use in
carto-parties and mapathons and by new mappers.

General changes or clarifications:
A residential road serves people who live adjacent to it.
An unclassified road connects settlements and collects traffic from
residential roads, tracks, and paths
A track allows people to access agriculture areas, but not connect to a
settlement
A path can function like an unclassified highway, but is restricted to foot
traffic or 2 wheeled vehicles
Highway = tertiary or secondary may be paved, but not by default.

Let me know if you have questions or suggestions.

Re: [HOT] residential roads within built-up areas

[Vao Matua]

At State of the Map Africa conference earlier this month we had several
discussions about road tagging.

The Africa Highway Tagging Guide
 has been updated to
reflect those discussions.

Personally I have found that thinking of the tagging hierarchy "upside
down" makes more sense than starting with the "important" roads then
proceeding down to roads of "lesser importance".
Numbers-wise there are more paths and residential roads than any other.
The most important transportation route for an individual is the one that
leads from their home to the village or town.  It could be a path or
residential road which would lead to highway=unclassified or
highway=tertiary.

One question that is useful to ask about the function of the road is "does
it provide a *collector *function?", does the road get used to help people
from various nearby locations get to a single place such as a hamlet,
village, or town? if the route provides access between settlements then the
road is highway=unclassified or highway=tertiary +.

One of the things that is confusing about the OSM tagging is that it is a
mix of function and construction. A motorway and primary highway may have
the same function, but different construction class. In the same way a path
may be a significant transportation route for a village or small town but
it cannot be highway=unclassified or highway=tertiary because of the
construction class that limits vehicles.

One of the things that was confusing for me when I started tagging OSM
roads was the highway=track tag.  A track as defined in OSM is not a
construction class lower than unclassified or residential.  It is a
drive-able route used to access agriculture or forestry areas without a
connection function between settlements. A track can also be found in a
park or game preserve, but should not be used for a road with a through
connection.

My opinion on highway=service is the same as Blake's, a road inside a
restricted access location (gated community or industrial facility)
wouldn't have the same function as a road with similar construction but
with public access.

Emmor

Re: [HOT] Buildings and residential areas: Buldings as nodes (Q1)

[Vao Matua]

My opinion is that buildings should be mapped as areas.
In un-mapped areas it would be best to create landuse=residential areas
first rather than quickly tagging buildings with single nodes. When it
comes time to trace buildings it is troublesome to convert single nodes to
polygons.
For existing single node areas they could be cleaned up on an as-needed
basis.

Re: [HOT] Fwd: Re: landuse=residential within landuse=residential

[Vao Matua]

Nick & John,

Determining where to draw the edge of landuse=residential can be difficult.
Here in Ethiopia most of the population lives in a rural setting where they
farm areas of 1 to 10 hectares in size.
http://www.openstreetmap.org/#map=16/6.9634/38.4408
There are places where people live in villages, but often dwellings are
quite dispersed.

I would suggest that an additional landuse tag would be appropriate.

landuse=rural_residential ?
landuse=agriculture_residential ?
landuse=pastoral_agriculture ?

Additionally the highway tagging needs to be updated as well.

highway=rural_residential
deprecate highway=unclassified for highway=minor_road

These are some of the topics that I am hoping will be discussed at SOTM
Africa in Kampala in July. http://sotmafrica.org/

Re: [HOT] Could we get more out of our mappers by asking for less?

[Vao Matua]

John,

I think there is merit to what you are saying.

The one caution I would suggest is that "If something is worth mapping it
is worth mapping correctly".  Here in Ethiopia I have spent a lot of time
adding nodes to roads that were digitized at a coarse scale.  Mapping
quickly doesn't have to be done crudely.
There is no troupe of magic mapping elves that clean up the rough mapping.

The next set of HOT projects I will set up will be roads/highways only and
then buildings only.

Keep mapping,

Emmor

Re: [HOT] Anybody has time to handhold me through untangling a task?

[Vao Matua]

Majka,

The mapping in this area is comparable to other projects I've seen in
Tanzania.
Over-mapping residential areas and paths is kind of overkill, but
personally I don't think it hurts to have them mapped.
The bigger concern I have is buildings mapped as lines, that is something
that should be mentioned to the mappers so they don't continue that habit.
It is always good to remind new mappers about the Africa tagging guide.

Thank you for taking on validation of some of these tiles, it can be messy.

Emmor

Re: [HOT] Highway=residential in Africa

[Vao Matua]

I would suggest that a tag like* highway=rural_residential* would be
valuable.
I often see dwellings in agricultural areas connected by a road/track/path.
To classify a road as "unclassified" has always baffled me.
Often in Ethiopia I see houses about 50 meters apart along a road which
connects to other similar roads much like a residential street would only
it is a rural/agricultural setting.

Re: [HOT] Difficulty in communicating with iD users

[Vao Matua]

Thanks Dale & Mikel,

JOSM and iD are just tools, each with their strengths and weaknesses.

I have made thousands of edits with both and demonstrate both when I lead
mapathons, most people choose to edit tasks with JOSM, but many like iD,
the important thing is to coach them to create good data.

If the HOT community can't handle a simple change of moving an ambiguous
term that describes what something is not ("Unclassified") to a term that
better describes what a feature represents on the ground ("Minor road")
then maybe the "Open" in OSM and HOT should be replaced with "Closed"?

It will take a long time to map the third planet from the sun, but we've
made a good start.

Re: [HOT] Groups/areas of Trees=> leisure=park?

[Vao Matua]

Mike,

I would suggest that natural=wood should be the first tag, if the area is a
park then the next tag could be leisure=park.  The OSM page on forest
has good
descriptions.

In Ethiopia often the Orthodox churches are in the middle of a small church
forests and would be tagged natural=wood, and land_use=religious.

I love trees but would shy away from tagging individual trees except for
landmark type specimen. There is a lot of mapping to do without mapping
trees.

Suzan,

I believe it is a watercourse, look at the location at level 16 with Mapbox

Another issue I see is the extra large Residential area polygons, they

houses.

I would appreciate the feedback from site visits.  It is difficult to know
if the imagery shows buildings or trees, paths or streams.
Hopefully the mapping will make things go faster in the field.

 Hi Pierre,

 I totally agree. I will ask for feedback.

 Also, we are trying to up our game in terms of local field mapping thus
 year. I guess there is no better validation.

 Bangladesh was super interesting, for example. Although the tracing was
 often way out, it was super important for the local mappers as they were
 able to reference their position via gos on their smartphones with their
 position on the field papers. With the combination of the two tools,
 incorrect landmarks were almost as good as correct ones. And of course,
 they were able to validate the tracing.

 It is also important, I guess, for people working with NGOs and HOT to
 manage expectations and make clear that tracing remotely is by no means
 fool proof! Variances in mapping skill, image quality, context etc...

 Look forward to discussing this further.

 Hi Pete

 Yes, the contributors are prompt to respond to MSF and other humanitarian
 organizations operational projects. And be sure that such feedback about
 these projects is most appreciated by the HOT contributors.

 Let me make some disgression suggesting more intensive collaboration.

 We are a techy organization and the big contributors appreciate the
 capacity to move forward and work more closely with the field teams, to
 explore workflows to better interact. Feedback is a must to keep the
 incentive to participate.  Even in the context of urgent projects, if the
 teams take the time to give minimal feedback, I am convince that this will
 assure a good progress of the Task Manager jobs.

 The article about Ebola refered by Russell this week, presented some
 criticism about the Ebola basemap quality relying it to the  Crowdsource
 mapping or import of Settlement place names with duplicates.  This shows
 misunderstanding about how we can collectively, the OSM community and the
 international organizations deployed in the field, build a coherent map.

 Crowdsourcing the digitalization of aerial imagery or data imports, this
 is only one step in building an exhaustive map that can support
 humanitarian operations. To complete the map, the volunteers from abroad
 need more interaction with the field team GIS specialists.  After mostly a
 year contributing for the Ebola activation and with all the GIS specialists
 in the field working for Ebola, we still see how it is difficult to go
 further then Crowdsource remote mapping and as a Global humanitarian
 community integrate the field data collection in a more coherent
 information system,  to share with others.

 Working on smaller projects like this one, this could be often an
 opportunity to progress and find ways to better interact.

 Pierre

 *Objet :* [HOT] Mayendit task

 Hi all, I planned to write an email this afternoon to ask for your help
 with the Mayendit task (http://tasks.hotosm.org/project/923). The MSF
 team need the data fairly urgently.

 However, when I just went to look, I saw it was already at 28%! This is
 amazing

 So, instead I will just say, keep up the good work. The team needs the
 data by mid next week, but I think that looks very likely to happen.

 If anyone has time to do a bit of validation, that would also be super
 cool.

 (I try not to post to this list too much about Missing Maps tasks as you
 are all already involved in so many worthy projects. This is an exception
 because of the task's urgent nature...)

 Thanks again!

 Pete

Re: [HOT] #923 - Mayendit, South Sudan - highways to ditches?

[Vao Matua]

It appears that the Leer-Mayendit primary road in the north portion of the
project is under construction in this imagery?

Is it flooded?  There appears to be quite a bit of water in the video.

Any tag requirements?

Regards,

Emmor

 Actually, I was considering mapping all the fences as well, because the
 patterns are really beautiful ...

 Right now I took a brave (or stupid?) decision to change some long
 stretches from highway to waterway=ditch. One was even tagged as 
 motorway_link
 http://wiki.openstreetmap.org/wiki/Tag:highway%3Dmotorway_link .
 With the imagery it is often quite hard to tell the difference bewteen
 paths or raods and ditches, but it seems to make more sense that there are
 many drainage ditches in those wetlands. And the end is a giveaway: roads
 normally don't end in rivers 
 http://www.openstreetmap.org/#map=16/8.1729/29.9339layers=H
 I wasn't sure about the middle structure though, this could be path or
 ditch. maybe there are path running along such ditches.
 What do you think? Or doesn't it matter at all, as no humanitarian units
 would need this information for finding the people? (At least it does make
 sense to remove the motorway, I guess ...)

 Also I found this video that shows some of the area:
 https://www.youtube.com/watch?v=6jbDQNj6X_I - it does look quite wet
 there, but of course this will depend on the season.

 The larger round huts are dwellings, the smaller ones are storage. The
 linear items around the buildings and huts are walls (barrier=wall).

 In South Sudan, actually it is generally fences and not walls. Check on these

 The buildings and huts should be labelled building=yes.

  Hi,
 I have some questions about this new project:
 In the western part there are quite unusual structures, there are many
 buildings
 stretched in long lines. Like here:
http://www.openstreetmap.org/#map=16/8.1325/29.9831layers=H
 I started mapping these as residential areas, unless there were only one
 or two
 single buildings - would you do that? Or is it better to just map the
 buildings?
 I can't even be sure there buildings are really used for permanent
 living, just
 assumed that. Maybe there is someone with mor knowledge of the area?
 I'm also curious what the many round strucures in the open area are.
 They could
 well be man-made, maybe something like haystacks (or whatever material
 would be
 collected there).
 Also I am unsure about the roads. There is one tagged as main road
 that's not
 even visible on the imagery. I guess that doesn't make sense
 (particularly as
 the other main road can clearly be seen as something like that), but
 didn't dare
 to touch the top-level structures.
 Thanks, and sorry again if I am asking in the wrong place!

Re: [HOT] Validation

[Vao Matua]

Nick, Blake  althio, Good practical advice.
I think it is important to remember that there are humans on either side of
the validation.
There have been times when I added a few features and then validated, other
times I start adding and realize that quite a bit had been missed and then
I'm kind of stuck and just finish it off.  Hopefully I'm not leaving a
similar trail for others to clean up.

A suggestion for the HOT Tasking Manager Stats page would be to add the
number of tiles an individual mapper Validates.

As John says we have a lot of tiles to map.

Map on

 My personal views is that statuses done/validated/invalidated should be
 related to progress and quality of the current state of mapping.
 We should not use that to give feedback or give implicitly a notation to
 previous mappers.
 Use comments (with @-mentions) for feedback.
 A notation of mappers is a very complex and different problem.


 Pragmatic / Real situation answers

 Empty tile or most work not done: invalidated, short comment.

 A bit of work left to do ie. a few missing elements or tagging errors. I
 would do corrections to bring the mapping standard up to required level, I
 would add detailed comment to provide feedback or guidance. If I am
 confident enough with the previous work and my minor edits, I validate
 since the tile is now OK. Otherwise I leave it to another reviewer.

 In between? It depends on the mood and available time obviously and the
 limits between cases are fuzzy.
 If I have too little time or it is too much corrections I would go for the
 comments only with @-mentions, most of the time with no further
 validation/invalidation. If I avoid invalidation I hope the comment is
 enough for track record and bring attention to previous and potential
 mappers. This is taking care of community over quality and I appreciate
 that opinions may differ.

 Question at what point should I invalidate?  The question arises when
 perhaps I've added a dozen settlements and half a dozen highways, I'm
 fairly experienced so fairly comfortable the work is OK after I've added in
 the validation but there is the question that I've added a dozen
 settlements and no one else will be validating.

 I'm looking more for pragmatic answers more than anything else, there is
 a concern that if I invalidate a tile it may demotivate a mapper and at the
 moment we have a lot of tiles to map.

 Thanks

Re: [HOT] Volunteering

[Vao Matua]

Saul,

I affirm the advice given by Mark and Rafael.
Don't be afraid to start mapping and contribute.
I would also suggest going to a HOT tile that isn't complete but other
editors have started on.  That way you can see how other people have tagged
features.

Regards,

Vao

 Hello,

 My name is Saul Karamesines. I'm a student of Environmental Studies at
 Utah State University. As part of one my curriculum, my Environmental
 Nonprofit and Volunteer Management class requires volunteer work. I learned
 of your organization from a previous GIS class, and I find your mission
 interesting so I would like to volunteer with you. I have experience with
 ArcGIS from my GIS class, and I've begun to learn OpenStreetMap's iD editor.

 How do I begin working for HOT? Is there a process I need to go through?
 How may I best be of service?

 Thank you in advance,
