[OSM-talk] virtual san francisco mapping party?

[Peter Miller]

Steve has pointed out to me that there is a real mapping party in San
Francisco next weekend which is great.

I still think that there is a lot of value in encouraging 'virtual' team
alongside physical one especially for the USA where the availability of
Tiger and Imagery data allows a lot of work to be done remotely alongside a
smaller team in the place itself.

I will add my name to the list of attendees for the San Francisco meeting,
making it clear that I will be remote. Possibly you could create a 'jobs
list', some of which can be done remotely, on the party page and see if
people sign up to take them on.

I have a few specific questions/observations based on the work I have done
so far.

1) The rail network data in the area seems very fragmentary. It may be
valuable for someone with good local knowledge to concentrate on that bit.

2) I have cleaned up and completed the BART network. I have tagged it
'subway' which may not be ideal, possibly 'metro' would be better. I am also
not clear if it shares track with Union Pacific through Oakland down to
Hayward. Also, if I say the subway is in a tunnel it is not rendered at all
in Osmarender. Currently it is tagged with layer=-1 without a tunnel tag for
the underground bits. Feel free to improve what I have done.

3) The runways and taxiways for small airports are too wide when viewed
close up using osmarender. Check out the airport near Foster City as an
example.

4) Nearly all the tiger roads are tagged as 'residential' by default. It
would be very useful to have a mapping of terminology between US names
'interstate' etc, and the OSM ones. I assume 'motorway' = 'interstate'. How
should 'trunk' be interpreted for the USA? What about Primary, secondary
etc?. I suggest that you folk update the map features with your
recommendations and ensure consistency across the USA.

5) At some stage I guess we will have a renderer that will using different
colour schemes for the road hierarchy for different countries to follow
local custom (Interstate shouldn't be blue for example) but that is not a
data collection issue.




See you Saturday :)
