Wait! You mean a robot ... Made a mistake!!?? Say it ain't so!

Sarcasm aside, it's not surprising. The article speaks so highly of the robots 
and the crisis peeps over the crafters and the arm chair people. But it has 
been my experience that unless the importer is skilled and regularly consults 
the locals, the result is invariably bad for the map.

The demotion of craft mappers and arm chair mappers to, effectively, bottom 
feeders does a disservice to the map. I map my local area and arm chair 
locations far away. I do not think those contributions are damaging or niche. 
My local work is for things only a local could know. And my remote stuff is, 
while based on the satellite, things that need refinement (better shaping) or 
things that are missing that seems beneath some mappers (such as service 
roads). No one seems to want to survey this type of thing or to make sure a 
road flows correctly. This is especially true for some of the robot work. 
Things are imported and left that way with no regard for confirming that the 
new data appears reasonable. One place I went over had imported streets that 
were not connected together, so I fixed it from my position thousands of 
kilometers away. As long as one is conscious of the need to defer to the locals 
and preserve information already in place, there is nothing wrong with remote 
mapping.

[Talk-ca] District of North Vancouver: Licence Check

[Henry Armitage]

Hello all,

I was reviewing the OSM wiki for Vancouver (more accurately, the Metro
Vancouver Region):
http://wiki.openstreetmap.org/wiki/Canada:British_Columbia:Vancouver#GIS_sources_by_city

In that, I noted that the District of North Vancouver's Licence is
given as "restrictive", but no reason nor exact title of the licence
is given.

The licence can be viewed on the "legal page" link at the top of
DNV.org's data page: http://www.geoweb.dnv.org/data/

The _current_ licence title is "Open Government Licence - North
Vancouver". As I say, I am not sure if this version is the licence
that "restrictive" refers to, from a quick review, it seems OSM
compatible the way it is written, but I'd like second opinions.

Thanks

Henry
