Yup, Over in Vancouver were talking a close look at it also :)

Awesome... i have no idea how you managed todo that, but great work :-)

Hi, another option that came up in OSM-CA IRC chat was noexit=yes  to
indicate road stops.  Perhaps using it in the fixme notes?

http://wiki.openstreetmap.org/wiki/Key:noexit

OTOH, local mappers would be able to check and see exactly what type
of road-end it is :)


> (2): Frank Steggink - bonjour Frank - has done a massive upload of forest areas, NE of Quebec city, using small tiles.  I used his experiment results to figure out the number of nodes that should trigger tile splitting. The Quad Tree algorithm usually creates tiles smaller than Frank's experiment.  It should be OK then.

P.S.  Ok, so there's no response about the idea for uploading the NTS
Tile rectangles and indicating what the status of the data in that
area is.   So is this not a concern for people?  And are we all
confident that we are just treating the data like top-quality Yahoo
imagery, where it is used to supplement the existing OSM map with more
features where it's needed?

If so, that's fine.  My concern is about overloading the OSM servers,
as there will be TONNES of data added into OSM over the next few
months / few years as this progresses.

So is the consensus that we WONT be overloading the servers, because
we do not plan on announcing to the world whats going on, and as more
local mappers find out about this, they will be working on their own
tiles.   Ie. I map my house, you map your house and eventually we'll
map the world?

Cheers,
Sam
