[Talk-us] tiger data - blame me for josm yellowness

Re: tiger data, blame me

Hi all,
I'm working on a good rebuttle, accept each draft is an essay driving
home a point. ;-)

Here it is;

For ALL GeoBase and CanVec data, we are treating it as a "sub-class OSM mapper"
we create a new login id for it, separating the regular mapper with
the "sometimes obnoxtious" mapper of the geobase/canvec import.

We are using AutoMATCH, from OpenJUMP and a nifty script, to make the
import as less 'intrusave' as possable.

We firmly believe that YES, the geobase & CanVec Data is good, BUT it
doesnt top someone physically on the ground observing the conditions.

What we do is leave it up to the person who made the tracks and
manually traced the features to decide on what todo. Myself & SteveS
and the others working on it, provide the 'system' and the 'tools' for
the local area mappers to physically view & preview the data before
importing it.

Yes, this method does take a REALLY long time todo, however it handles
the number 1 fundemental of OpenStreetMap - respect other mappers work
& communicate directly with them if you are unsure of why the features
were mapped a certain way.

Through discussions you can find out reasons, and ask others for logic & facts.
If no agreement is found, we delete the geobase/canvec feature in
favour of the local OSM mapper. ~Until i am physically on the ground
seeing the area im person; i have no way of arguing counter to what
the mapper says to be true.

We have the origional geobase data, and can use it to be 'viewed' or 'traced'.

Remember the purpose of making a map; So anyone from anywhere on the
planet can print the map, go to the area & navigate based on common
symbols and line types that are easily understood.

In otherwords, the entire OSM map is in constant need of revision, it
will NEVER be complete, as it will always take on the ground
observations - there is always construction and map features changing
- thats what makes it fun :-)

I hope that helps,  im happy to further explain my points.

cheers,
