[Talk-ca] Duplicate BC, Canada geometry

[Bryan Crosby]

I import exclusively in Northern BC and to my knowledge I am pretty much the
only user who CANVEC's up there.  I too download the whole CANVEC sheet area
in JOSM.   I often import overtop of Mr. Dunn's previous GeoBC road imports,
but they are rarely, if ever in conflict.  I always retain his GeoBC road
imports and delete the CANVEC unless they are not present in the GeoBC
layer.  There may be a few road duplicates up there, but they would be minor
errors and not indicative of a trend.

I haven't been doing much importing recently, but whenever I do, I _always_
download the area in JOSM first before adding anything to make sure I'm not
duplicating existing data. Without seeing an example, I really can't give an
explanation of what's happening.  As far as my CANVEC importing goes, all
but a handful have been on Vancouver Island. I've stumbled upon and fixed
other peoples' duplicated data in the past, but I haven't knowingly
duplicated data myself. I'd love to see where this is happening.

Hmm, I think the last time I did imports in BC was back in 2010, and I
thought I was careful about leaving the map in a correct and consistent
state. Azub's imports are all in the Prince George or north area, and I
definitely know I haven't touched that area in a long time. Got any examples
or changeset numbers?

 

The nature of doing imports like Canvec tends to be spread over large areas
and large amounts of time. Any suggestions on techniques for coordinating
efforts? An email to the list saying "I'll be working on Prince George area
this week"? A shared spreadsheet?

azubimport (http://www.openstreetmap.org/user/azubimport) are duplicating
way geometry from multiple sources, in some cases within a few days of each
other.

 

Will the three (hopefully there are not more) of you please coordinate your
efforts, review your recent work, and de-duplicate way geometry and tagging
in BC, Canada (and elsewhere, if applicable).  I presume you've been
engaging with the import list, copied  ...

 

Thanks and best
