Hello portugese mappers,
during my bugfixing work in Portugal I came across an area in
southwestern Porto (Vila Nova de Gaia) south of river Douro where the
data in OSM looks striking similar to the Google data [1]. What's really
weird is that OSM data is showing the same alignment of this road
through a quarry [2].
The data was submitted by one single user [3] during november 2008. Back
in 2008 there was no Bing imagery. Could anyone of you please kindly get
in contact with this user and ask him for his sources?
Otherwise me might have to forward this to the Data Working Group [4].
Regards,
Claudius
