[Talk-in] i have doubts in syncing gtfs and osm data

[Sanjay Bhangar]

Ganesh,

Thank you for checking on the list.

This seems quite risky to me, and seems like it would require a lot of
due dilligence before attempting a merge.

I think this would qualify as a data import, and as such, you should
read the Import Guidelines:
http://wiki.openstreetmap.org/wiki/Import/Guidelines

It would be helpful if you gave some more details like what data this
is, where you sourced it from, and ideally links to the raw GTFS data.
Also helpful would be links to code / scripts that you intend to run
to transform this GTFS data into OSM changefiles.

Conflation / merging in OSM is *really hard* and I would be skeptical
of any process that attempts to do this in a fully automated fashion.
HOWEVER, if the data is legally able to be added to OpenStreetMap and
you can share the data here and the community feels like it would be
valuable (which it seems like it probably will be!), I'm sure there
should be community members who are able to help out, and perhaps we
can work together on a part-automated / part-manual process of getting
this data in or so, to get the benefit of the data-set, but make sure
we have human eyes checking for conflicts and making sure nothing
breaks :-)

Thanks again for your enthusiasm in adding data to OSM, and looking
forward to seeing the data-set and hoping that the community can work
together in helping you get this data in.

All the best!
-Sanjay
