Malheureusement John, il y a eu pire comme problèmes de qualité pour l'ouragan
Matthews.
Pouratant, on prétendait supporter une urgence, puis une fois les medias
ailleurs, on arrête les mapathons et on laisse les problèmes. De là mon
article sur HOT qui disait que c'était une cause oubliée.

I completely agree with Pierre on this one. Especially if its going to
involve more than one University.
In Ottawa we imported the building outlines first through opendata. Then new
mappers can just add tags. Just as a reminder here are some buildings mapped
in Africa probably in a maperthon and its not untypical.

I don't think we have the resources to clean up the map afterwards. This is a
project that Stats is interested in to sell the data. There have been some
conversations about the use of paid mappers this might be an appropriate use
for them. I'm not even sure we have enough resources to have an experienced iD
OSM mapper at each location where they will be mapping and ideally it should be
two.

Hi all,
my 2c:
If we want to have a bunch of new to OSM people map things, I would suggest
that these is a physical location with experts present. As we see with the
Carleton University example (not uOttawa), it's hard to get new folks on
board... i would guess that although there was training provided to Carleton
Students, it was done as a lecture rather than a lab.
I was introduced to OSM mapping by joining a meetup, getting an intro and then
everyone sitting around one big table (experts and new folks) with their
laptops and start working through whatever the project was. It lasted 2-3
hours. I thought it worked well, and could start working through things on my
own after, but still asking questions of experts. I still made mistakes, but
having experts sitting in the same room to ask questions was invaluable for me.

Encore plus que le monde rural, il y a tout le nord à cartographier. Puis
les divers projets de Mapathon on montré que de grandes vagues de nouveaux
contributeurs arrivent rapidement, cartographient souvent sans la précision et
la qualité nécessaire et quittent après souvent une seule soirée de
participation.
L'objectif de tels mapathons doit être repensé. Il doit viser à initer et
former des nouveaux contributeurs. L'exemple de l'université d'Ottawa nous
montre comment ces groupes ont besoin de support. Il ne s'agit pas de faire de
la publicité et les convaincre de démarrer des projets. Nous aurons ensuite à
réparer les pots cassés.
En Haiti, lors de l'ouragan Matthews en octobre 2016 des vagues déferlantes
de contributeurs ont laissé pendant deux semaines des vagues déferlantes de
mauvaises données. Personne ensuite pour réparer.
Vite, vite, repensons cette approche.

I'd be pleasantly surprised if there was much intersection between
"rural" and "high-resolution imagery" in Canada. Our rural population
density is very low.
