<DIV>G'Day Australian Mapper<BR><BR>Perhaps someone from Natural Resources
Canada (the Federal mapping agency) could give a better answer, but my
understanding is:<BR><BR>- CanVec originated from the NTDB (National Topographic
Database) which is essentially the same data as is used for the (sometimes quite
out of date) 1:50 000 scale National Topographic Series maps. That is all
Federal data.<BR><BR>- GeoBase is an initiative which aims to reduce duplication
of work / costs by having Provinces (equivalent to Aus. states) or other
entities supply "best" data to the Feds.<BR><BR>Thus GeoBase would actually be
an example of the left hand working in partnership with the right hand.<BR><BR>I
believe CanVec is being updated with any better sources as they become
available, e.g. National Roads Network (NRN) gets migrated into new editions of
CanVec.<BR><BR>I believe there are many data themes that are in CanVec which are
not in GeoBase, and presumably never will be in GeoBase unless the initiative is
extended to include agreements for those themes.<BR><BR>If I have misunderstood
anything I'd be delighted to be corrected.<BR><BR>Now, what is "CommonMap"? I
had never heard of that until now. A quick web search gets me here:<BR><SPAN><A
href="http://commonmap.info/w/index.php/Main_Page" rel=nofollow
target=_blank>http://commonmap.info/w/index.php/Main_Page</A></SPAN><BR><BR>It
looks to me like it is a very similar concept to OSM, apart from licensing
perhaps. So it makes me wonder if we have a "left hand - right hand" situation
there?<BR><BR>John<BR><BR></DIV>

Hello Canadian mappers,<BR>> <BR>> Sam Vekemans suggested I ask the
following here:<BR>> <BR>> What is the relationship between CanVec data
and GeoBase data?<BR>> <BR>> To this layperson they seem to be two
initiatives hosted by the same government that seem to have similar
objectives. Almost like the left hand not talking to the right
hand.<BR>> <BR>> Can anyone explain briefly the differences? For
example, it seems to me that GeoBase is "closer" to the data authors, and CanVec
feeds from that, and CanVec concentrates on having complete coverage at
particular scales (like 1:50k).<BR>> Am I on the right track?<BR>> Is
there a government document that goes into detail?<BR>> <BR>> My interest
is to pick out the best bits to seed CommonMap with. I'm looking for
accuracy and timeliness.<BR>> <BR>> <BR>> Brendan<BR>> <BR>>
