[OSGeo-Discuss] Batch geocoding

[JP Glutting]

Hi Hans-Jörg,

I am not aware that Barcelona (the city?) has a very open geodata strategy,
but that certainly would be nice. If you know of anyone in the area who
might know more, I am more than willing to contact them.

I have the addresses, do you mean the coordinates? The address format is not
ideal, but I am pretty happy with them, as they seem to geocode well in the
tests I have done.

The Yahoo API allows geocoding of 50k addresses a day, which is plenty for
what I need. I am going to try to use that.

Cheers,
JP
