[Talk-ca] Duplicate overlapping roads...

[G. Michael Carter]

Sam always says I should let people know what I'm up to.   Today I'm 
actually going to listen... ;-)

I'm working in three areas currently, outward in circles around: 
Orangeville (040P), Pickering (030M), and Rock Point PP (030L).   (and 
trying to pull in Lake Ontario shore line)

I'm creating some duplicate roads, temporarily, in the process.   I 
wanted to detail my process here in case anyone notices them and starts 
scratching their head.

The process I'm following:

1.  Remove all existing OSM objects from CanVec grid.  (mostly stuff 
I've already uploaded)
2.  Merge with existing OSM data on the layer.
3.  Delete any "attribution:GeoBase highway=*" roads.  Trying to 
preserve any roads that CanVec doesn't have but it's hard since a lot of 
the areas I'm doing don't have any GPS tracks.
3a.  Where the duplicates come in... I'm leaving any roads that go off 
grid, at least to an area I haven't processed yet.  Then when I get to 
that area I remove/merge them.
4.  Go over the area and merge/delete any roads manually added or that 
have no source (where no GPS track)
5.  Merge any duplicate objects, that I missed or previously existed.

Areas I'm staying away from: Toronto!  I'm not going near that one, too 
much existing or conflicting data.  I'll let someone living in Toronto 
to pick up that mess. :-)
