Hi, this is a clarification of the source and an attempt to prove the source. Traffic signs visible in photographic imagery were used as a source of information. Google Street View provides photographic images. Google's own data of street names was NOT used as a source.
In Woolwich Township, relations were created for only some of the numbered township roads. Traffic signs visible in Google Street View photographs are often too blurry to be readable. In Woolwich Twp, relations were only created where traffic signs were readable. Here are several examples of readable signs in Woolwich Twp visible in Google Street View:
In these three images, traffic signs have the road numbers contained in circles:
On these signs, road numbers are simply paced beside road names:
As well in North Dumfries and Wilmot Twps, relations only were created where traffic signs are readable in Google Street View. Wellesley Twp has a pattern in the numbering of its roads. (e.g. Wellesley Twp uses odd numbers for roads running east and west. Even numbers are used for roads running north and south. Every number in Welesley Twp is suffixed with a letter.) Knowledge of the numbering pattern was used to create relations for Wellesley Twp and thus not every road number had to be readable in the photographic imagery.
I could provide more explanation of the source and more examples of photographic imagery. Thank you.
