Hi all,
Dale made some great points.
(and so i add my own ideas)
1 there are post IMG files that add up to 50gigs.
(when the topo contours are removed, it would be a bit less.)
If its spare computing power u need, my bets is that a college or
university would be able to donate a powerful computer, right?
2 what is the goal of the project?
We touched on it before, but DO need to dig further, as we have more
facts available on one side.
IF our goal is A
or B, we have a different approach.
A- to create the most accurate map of canada.
A1- we can never be uptodate with government data, as it is an ever
changing master database, with many users looking for different info.
A2 -the best we can achieve is to create a 'geobase/geogratis update
import program'
A3 all imported data needs to have an NID, for the sole purpose of updates.
A4 for those areas in canada that were 'missed' during the last
geobase shapefile compiling, it will show up in a year from now.
B if our goal is to create the best 'osm user' compiled map, we have;
B1 the constant problem of trying to manually merge the new data
available, as the NIDs would be out of sync
b2 the ability that only roads with no 'extra tags & relations' be
removed, BUT We keep a back up of the old data for reference
b3 we know that we CANNOT be upto date with geobase;
i propose that instead of just letting the train go by and picking
what we want; that we dump all of the trains contents, spilling over
mapped areas.
Then worry about the update program later.
'cause by the time a new update is available, we would already have
all the features for the cyclemap/hikingmap/wikitravel map.
So just merging of the 'richer' osm data would be needed.
I dont see that as a problem if we can agree that;
if we can add the 'geobase2osm:fixme' tag
cheers,
sam
ps, u had other questions that i'll get to.
Happy heated discussion day :)
