[OSM-talk] Suggestion more complete mapping verifactiion

[John Baker]

Thanks Dave for the useful reply - so many are not. That explains a little
more.

I was a little presumptuous that his information was available. But also, to
be honest, I am surprised that people involved in heavily mapping (like many
here) do not have street info like this - even if they cannot/do not use it
for this project.

Yes I understand the potential problems with this data online and stated
that before.

Anyway here are a few scenarios for you:

a) You can still lookup the street data though with the RM or OS etc
programs that is what they are for. If I got an "official" street name
source from RM, etc and made a list myself, looked those up in the AtoZ
and and walked around myself. Would it be ok to put this data in
OpenStreetMap?

b) At a mapping party (or follow up mapping parties when it is nearly
complete), etc. someone hands people a list of a few names of streets that
they might want to check out that might have been missed so they can lookup
in their AtoZ. Would the data collected be ok to be put in OSM?

c) If someone posted a link to this newsgroup to a webpage with possible
"Easter Eggs in RM street data in Cambridge", etc and people went out
and checked this and realised that some of these streets were not in OSM
database. Would it be ok to add them? Maybe with links to multmap,
streetmap, etc (2 different data sources) of the roads.

d) If someone posts to say Heddon Street in London W1 is not in the database
here is a link:
http://www.streetmap.co.uk/newmap.srf?x=529233&y=180753&z=1&sv=heddon+street&st=1&tl=Heddon+Street,+W1&searchp=newsearch.srf&mapp=newmap.srf
Is it then OK for someone to walk down Heddon Street with a GPS and map this
road in OSM?

I wonder what you think of these?

I don't want to auto-correct the streets or copy from multimap or something
that some here seem to think. Just to go out and manually check them.

Obviously some can be paranoid with the legal stuff (and it is easy to do
so) and on the same level of legal paranoia you probably shouldn't use paper
based maps for planning mapping parties but I imagine you do. Obviously
caution is needed I am not arguing otherwise.

Legal areas are complex but there seems to be a load of leeway here IMHO.
