[Talk-us] Planning to "import" speed limit data for Florida

Response I received in 2008
"GIS data provided by the FDOT Transportation Statistics Office isconsidered
to be in the public domain and can be used for any purpose."

I had looked at this a while back and gave up on it personally due to the
high amount of manual activity needed.  I just did not have the time to do
much with it.  Not to mention the problems of keeping track of what had been
worked on.

Would you walk thru your process steps so I and perhaps others could learn
from them?

For me it was partly an issue of the data covering a large land area, then
only able to download small chunks from OSM to edit.  Anything else and JOSM
took so long to do anything (this is better now, but I think still true).
Constantly switching between the layers to get the info, then back to edit
the OSM data to match...  It all just seemed way more labor intensive than
it needed to be.

Anyways that is why I am interested in how you plan to attack it.
