[Talk-us] Address data for Miami Florida United States

Fri Sep 14 20:28:57 UTC 2018

Great stuff, Leif! I will catch up with this project over the weekend and
will provide some input.

I have access to a few workstations with a bunch of memory so I can help
out with converting/processing the input data if needed. Just let me know.
I don't think of the size of these datasets as an issue in terms of
processing (not even the buildings). As you said, splitting them up into
smaller chunks or using a totally different toolset would also work.

Finding enough people to review and put the data on the map will be a
bigger issue in Miami, imho. You guys are planning to implement an entirely
manual approach, correct?

Cheers,
Levente
