Re: [Talk-ca] Validating existing data in Ottawa area

[Pierre Béland]

Paul,

No I dont know.  

After I asked for data in july compatible with ODbl license, I was contacted by 
one person asking me to explain about licenses incompatibility.I will try to 
re-contact this person and see if things are moving a bit.


If there are people on the list that think they can help on this matter, please 
let me know.

For the Québec municipalities administrative boundaries there were
discussions on this list about a month ago. We plan to import at once using
data from government of Québec.  I communicated with the government Données
libres site and wait for their approval.

In my experience the addr:interpolation ways imported from CanVec do not
have reliable geometries, particularly in new subdivisions in Aylmer. (See,
for example, the new stuff near Wilfrid-Lavigne, at the far north end of
the neighbourhood.) It's not just a matter of being shifted over a few
metres.

I coded the "very approximate" Aylmer boundary myself (knowledge:
unreliable best guess) as a suburb of Gatineau, which itself is not shown
yet on the map. Looking forward to the boundary data for Quebec.

Sounds like we should stand by to hear the outcome of your work.

OK, the particular spot I was concerned about for misalignment was above 
Alexandria Bay. It's a little neighbourhood off Ch. Lattion, including R. de la 
Spartan, R. de la Lobo, and R. de la Cortland. CanVec shows R. de la Sparta 
running further north and another street or two coming off it. One of us really 
needs to run a GPS trace through there.

Further west a number of the streets are lacking names.

Surely you'll need CanVec, if only to get the administrative boundaries of 
Gatineau. Is the region broken down into sub-regions, so Aylmer continues to 
exist?

I'll add that I know how to get CanVec as images in JOSM, but I don't know how 
to get the encoded data.

Re: [Talk-ca] Validating existing data in Ottawa area

[Tom Taylor]

Thanks for your suggestions for tools to do the work.

I reviewed the region N 45.40-.44, W 75.86-92 last night. There were a 
lot of areas on the west edge of Aylmer, PQ, where the validator 
complained because land use area boundaries had been partly made up with 
roads or with sides of adjacent land use areas. I got quite good at 
snipping away existing connections and creating new ones that made 
everything disjoint. I do question the objection to land use 
adjacencies. In the previous block I worked on, I left in place an 
adjacency between landuse=water and landuse=wetlands, because it made 
sense to do so.


The Aylmer region is missing a number of roads shown on CanVec, and has 
a lot of unnamed roads. One area done on the basis of Bing is misaligned 
by up to 15 meters with the CanVec image. Rotation as well as 
translation is involved. I'll probably take a drive to that area and 
sort things out, but it really seems like some importing from CanVec is 
needed. That is especially so for the administrative boundary of Aylmer, 
which is marked with a note saying it is very approximate. Besides, I'm 
trying to remember if Aylmer got incorporated into the new city of Gatineau.


Lots to do.

Tom Taylor

Hello Tom

If you (and all other mappers) want to coordinate your work, i suggest you
using Mapcaft: You can create a "pie" with Ottawa and then split all Ottawa
area into several small "slices" :
Each user (mapper) can appropriate one (or more) and others have to take
care of "non-appropriated" slices.
You can manage and follow the work in progress by the "1-9 status" of each
slice.
See some examples :

Another option to quickly find duplicate ways and routing errors is to
use the OSMInspector

[Talk-ca] Validating existing data in Ottawa area

[Tom Taylor]

While uploading edits from JOSM, I have been encountering validation 
warnings and occasional errors from others' data. I've done my best to 
fix them up.


It finally occurred to me that I can run the validation tool after 
downloading OSM data, without adding data of my own, and clean up an 
area that way. I've started a systematic effort to clean up the Ottawa 
area, using bounding boxes extending .04 degrees in latitude and .06 
degrees longitude for a manageable size. My first box was to the west: N 
45.40-44, W 75.92-98. The biggest thing I found in that area was a lot 
of duplication because the same objects were downloaded from CanVec 6.0 
and CanVec 7.0.


I'll be working my way east and south from this starting point. I 
suppose I should write this up in the Ottawa Wiki so others can coordinate.
