[Talk-ca] Geogratis vs. GeoBase

Well then if thats the case, then i think that we need to fix up the wiki
page to reflect that. .. and state that GeoBase is 'Natural Resources
Canada' which IS the GeoGratis website portal showing the other sites. ...
(Gosh this government is confusing ;) ..  aargh! ...

CanVec data
http://geogratis.cgdi.gc.ca/geogratis/en/whatsnew.html;jsessionid=72B34CD564115465A56B9C6753C65951#canvec-20081103

We need to make a wiki and explain this in english :)

And So...  if this is true (that OpenStreetMap is cool with importing
Geogratis data) ... it also has water features database, then how I see it
is that;  ...

This is an EVEN LARGER announcement than the previous one.
... were talking EVERYTHING that is available on the ibycus topo... and
more. Like the boundries for First Nations people... even the map of the
receding ice in the artic circle is possable to have shape files for. ...
this IS BIG.
GeoBase is just a little baby when you compare it to what is available.  :-)
 .. we got many thematic maps and maps showing the names of towns in
history, maps showing population distribution, .... all this stuff is Top
quality maps where people can use it as a base to draw buildings from,
(export OSM to Arc files)..


If we can find out the exact places where Dale found all his data to make
the Ibycus Topo... and use that list (just exclude the Topo lines, that can
be included with the satalite images plugin or vms layer) ... and so each of
the shape files can be imported, with the script.   .... OR we can work
together to make an Ibycus topo 3.0  using the most recient info.??

The script includes all the GeoGratis sources along with the data (so we
know where it came from, and making sure a tag says 'geobase'  or 'CanVec',
is listed. .. that would make it alot easier... then just use the same line
type tagging as dale did, as it matches up to what we like for OSM.

I know that it doesn't match the license... but remember, it's only the part
AFTER the rendering process that is covered under the UMP (unofficial map
project) so at the point where the files were saved as .mp and were
an amalgamation between all the different datasets.

(This was why i was pressing for using the mp2OSM python script)  .. so i
think here, all we need is really the OK from Dale.
.. if he can explain how to bring all the new data which is available out
there all onto neet tiles to have them as mp files.. i think thats all we
need.

Why re-invent the wheel?

Or perhaps im not getting it. .. Can we explain;

1 Where exactly the data in the Ibycus topo came from.  (if it was a big set
and split up, or how it was done)

2 If everything on the Ibycus Topo is now 'old'  ... how to we find the new
stuff??

3. What's this Atlas of Canada
<http://atlas.nrcan.gc.ca/site/english/maps/topo/map>thing?
why cant i download anything from that page?

...
Thanks,
Sorry if i'm sounding a little frustrated, it's just that we have a whole
bunch of talented people on this group, and all with experience in their own
field of work, and so, we have all the pieces of the puzzle.... its just
challenging because everyone is seeing it from a different angle. ... ie. ..
if you never actually saw or used this Ibycus topo map.. then you would have
no idea about it's significance to the openstreetmap project.  ... and yes,
going for it, and importing all the tiles that have less than 100 OSm roads
would certainly show everyone how much stuff is available.

Cheers,
