Ceux qui proposent de démarrer de nouveaux projets d'import doivent doivent être prêt à consacrer beaucoup de temps à la coordination et accepter toutes les frustrations et difficultés.

The first is local adding local knowledge to the map. The other I'll
call armchair mapping. When Stats Canada did the pilot it tapped the
local Ottawa mappers who meet physically.<br clear="none"><br clear="none">I would agree that
amongst mappers with the most edits there is a high number of retired
people and those with disabilities involved and these may not be
visible. Tapping them for groups coming together to map can be a
problem.<br clear="none"><br clear="none">
In my view typically the most productive mappers are those with a
special interest. Adding WiFi access or churches for example or even a
change of street name.<br clear="none"><br clear="none">We also have a number of teachers who
would like to use OSM and in particular the building project to involve
their students. We get a fair amount of data added but the quality can
be questionable. HOT and others I think have found that using a
restricted set of tasks and tags works best.<br clear="none"><br clear="none">My personal feeling
is giving feedback is useful. So the challenge for the building project
is how to engage people. What are the most useful tags to add?<br clear="none"><br clear="none">I'd
suggest some sort of web site giving the number of buildings mapped and
the tags that have been added by city. Graphs with time as one axis
would be nice.<br clear="none"><br clear="none">Certainly certain activities are more complex than
others. Importing buildings is not a task I'd suggest for teenage
mapper with twenty minutes experience. Breaking out the tasks is a task
in itself and for 4 million buildings I think it could benefit from a
project plan.<br clear="none"><br clear="none">I think we've seen with the 2020 project that just
saying it would be nice to have by is not really enough to sustain it
but who would do it I'm not sure.<br clear="none"><br clear="none">Cheerio John<br clear="none"><br clear="none"><br clear="none"><span>Jonathan
