[Talk-ca] Canada Import chart

[Sam Vekemans]

Hi Frank,  & cc: talk-ca,

I think I've done enough import for now. 9 1/4 sheet of data. The 1/4 sheet
> was a section near Quebec City (021L14) with a lot of data and a lot of
> cleanup necessary.


When you say 'sheets' im assuming you mean NTS tiles right?

Here's where my thinking is.   We break down the process to 3 steps...
1 - Data conversion:  by converting the geobaseNRN directly from the gml
file, and skip roadmatcher, and make the complete .osm files.  We then make
these full tiles available.
They dont need to single tiles, you can group them how you like (just keep
to the grid boxes)

2- Data copyover (rather than say 'import') as its manual.
This way, our focus in on just getting the data available.  Local people can
be working on the manuall copying over of the roads that they want.   So if
they were the one that did the initial imagery tracing, they have the option
to swap or not.  and would be able to attach the ref tags and relations
needed.

3 - Roadmatcher results.  Having these available as an .osm file, so users
can copy might be better than importing.

Also another sheet (021L11) had the same problem. When looking at the data

So this way, our efforts are in the actual conversion.  At this point, only
4 or 6 people in Canada know how to actually use RoadMatcher and
geobase2osm.  (have a GIS background) Everyone else knows how to use JOSM,
and can open up a .osm file and start copying over the data.   It's not
essential that we record WHO is copying over the data, as long as 1 person
in each tile area is listed as a contact to figure out WHO is doing the
import copy.   Usually, it would be 1 person per tile, but for busy areas it
would be 2 or more.

(fyi, on an aside) the contours.osm converted file and the SHP files will be
available in the 'extra' folder of the canvec2osm (data conversion
script).   I just got word about the "OSM Atlas" project, and to get
contours, the shp files are needed, to make the PDFs.

Do you think i should make ALL the SHP files also available for all the data
(right now im deleting them, after conversion)?  So then we have a origional
copy of it, rather than just my converted version.   (since the data gets
updated, the older version might not be available) to make the DIFF shp
file. (for what was added since last time).

Awesome, keep up the great work!
I know that it's a tedious task... hey, why do you think im working on many
things at once (also schedualing meetups and such), as well as tackeling the
new Ontario datasets, among other things?   .. but these next 2 weeks im
trying to stay on task :-)

Its a slow work in progress, but as long as everyone out there knows what
everyone else is doing, then we should be pritty ok. ... and keeps the
communication lines open.  (cc:talk-ca)  which was my error about the latest
canvec2osm script progress.

Although it's nice that im doing all this work, but if i dont tell anyone
what im doing (working on), it may as well be not doing anything.

Fortunately, we all learning from eachother, and "paving new road" :-)
