Hi all,Im pleased to announce that Beta v0.30 is now available to view and
sample.

The sample OSM area is available here, so you can view the file with JOSM.

and here is the latest rules.txt file

I made a few changes, for example.

point,CODE,2600010,canvec:CODE,2600010
point,CODE,2600010,canvec:generic_code,2600009
point,CODE,2600010,canvec:entity,Mining area - ( Zone d'extraction de
minerai )
point,CODE,2600010,canvec:entity_definition,Area or site where minerals are
extracted; including sand; broken rock; gravel; and clay.
point,CODE,2600010,canvec:value,Mine underground operational - ( Mine
souterraine opérationnelle )
point,CODE,2600010,canvec:value_definition:Mine,An excavation or tunnel in
the earth from which mineral substances are extracted.
point,CODE,2600010,canvec:value_definition:Underground,Under the surface of
the earth.
point,CODE,2600010,canvec:value_definition:Operational,Can be used or is in
full operation.
point,CODE,2600010,landuse,mining
point,CODE,2600010,location,underground

You can see that it looks closer to what the canvec catelogue has listed.
So rather than weeding through the wiki, the definition of the tag is
available in the data.
With over 300 map features, having the original entity & value listed, it
makes it easier for people to go down to the last 2 tags and change it where
needed.

The process for this import (IMO) will be slowly and steadily. .. I'd like
to make sample areas for many parts of the country (as i did before) so
people can go through the data and check and see what tags i used, and if
they need to be changed.

What i want to avoid is having to revert changes, if tagging errors are
found.   (hopefully they will be found before i start importing more)
By working on it tile by tile, different users will be able to import each
feature slowly and migrate the data with existing OSM data.

We know that this (CanVec & GeoBase) data is not to over-right existing OSM
data.. but to help out.  The data is VERY basic, as you can see, and needs
more tags and identifying features. .

Ideally, this CanVec data will ONLY  get imported to areas that have ALREADY
been filled in with GeoBase Roads. .. So Im asking for feedback, is it a
good idea to include the CanVec roads, so they can be used to trace where
needed?

Anyway, Im still working on minor tweaks, and corrections.

Let me know if you want a sample area for where you are.

Thanks,

P.S. I also sent this message to GeoBase, as im wondering if and when the
next update of the GeoBase/CanVec data will be, and what kind of changes to
expect.
