[Talk-us] Durham and Chatham County Address Imports (North Carolina, USA)

[Leif Rasmussen]

Hi everyone!
I have finally verified the license on the Chatham County, NC address data
which includes about 44,000 address points.  It is public domain except for
that it has a "no direct resale" policy that allows indirect resale
(includes other data), which is compatible with OSM.  Durham County, which
uses the ODbL has also produced address data.  I will be completing both
the imports this weekend.  Some discussion has taken place about adding
buildings in Durham at the same time as the import, but to keep everything
more simple, I have decided on just adding nodes for now and then merging
with buildings later.  This would reduce complexity and help everything run
more smoothly.  I will upload all of the data alone.  This helps keep
everything more simple, leading to fewer mistakes.  I do not see very much
benefit to having several account all importing the data.

Details:
Size of both imports combined: 190,000 addresses
Date of upload: Saterday and Sunday, 21st and 22nd of July, 2018
Type of import:  One time with JOSM in 20 changesets.
Account:  LeifRasmussen_import

Please let me know of any concerns of ideas!  I would love to improve the
import as much as I can.
Thanks!

FAQ



Why did you do this?

I wrote scripts to joined them myself to lessen the impact
of doing a large join on Lambertus's server.  I've also
cut them in large longitude swaths that should fit conveniently
on removable media.

Can or should I seed the torrents?

Yes!!  If you use the .torrent files, please seed.  That web
server is in the UK, and it helps to have some peers on this
side of the Atlantic.

Why is my map missing small rectangular areas?

There have been some missing tiles from Lambertus's map (the
red rectangles),  I don't see any at the moment, so you may
want to update if you had issues with the last set.

Why can I not copy the large files to my new SD card?

If you buy a new card (especially SDHC), some are FAT16 from
the factory.  I had to reformat it to let me create a >2GB
file.

Does your map cover Mexico/Canada?

Yes!!  I have, for the purposes of this map, annexed Ontario
in to the USA.  Some areas of North America that are close
to the US also just happen to get pulled in to these maps.
This might not happen forever, and if you would like your
non-US area to get included, let me know.
