[Talk-ca] broken forests in eastern Canada

[john whelan]

His goal might be to improve the data quality and that us something I'm in
favour of but the CANVEC data was imported over a long period of time.
Deleting the imported changesets on basically a whim is not improving data
quality.

Yes some of the data could have been better imported, but Canada is big.
Forests are larger than JOSM can download.

The choice in many areas is no data or CANVEC data and I know what I'd
prefer.  CANVEC comes from a number of sources that were the best available
at the time.  Some sources are good, some not so good.  By deleting
everything then you're left with nothing or heaven forbid highways traced
from poor quality satellite images that were sometimes 100 metres or more
out.  For example in Quebec the sources are quite different to Ontario.
House number ranges I don’t think were available for Quebec for example.

Forests and lakes maybe one problem area in a particular province but
buildings, power lines and highways are fine.

The traditional OSM way is for the data to be refined over time.  The
CANVEC data is verified and enhanced and that is currently what is
happening.

We do have a number of mappers in Canada who have more experience than
Michael, we worked with the Federal Government to get the data released and
although there are some problems with it the vast majority is of good
quality.
