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?

Hi,

Very pleased to introduce Alex Glynn (
https://www.hotosm.org/people/alex-glynn/) who joined HOT last week,
managing our Communications activities globally! Excited to have Alex on
board to help bring HOT work alive through more and better comms - please
give her a warm welcome, and let her know any ideas you have for HOT Comms
going forward!

Important to note the guidelines are suggestions not enforced requirements of 
the OSMF. More on that in the blog post 
https://blog.openstreetmap.org/2019/02/09/organised-editing-guidelines/ 
My opinion is master list of mapathons is a very good idea. I don’t think the 
wiki is best system suited to be the place for that primary list. Another tool 
could mirror to the wiki for archiving purposes.
I agree with Pierre. Data quality needs to become a primary focus of these and 
other mapping activities asap. Otherwise it’s not valuable experience for those 
present or everyone else working with OSM data. I think that will take more 
than trend, but a substantial direct investment by HOT, Missing Maps and others 
in systematically operationalizing data quality improvements across through 
training, monitoring, etc.

Adequate training material and mapathon procedures need to be developped for 
Live data monitoring, interaction with newbies, and correct immediately quality
