[OSM-dev] Problems with TIGER Conversion

[Al Wold]

Dave,
It looks like I'm getting missing data (I think mainly entire ways are
missing) with the 0.3 version.  I had a file that seemed more complete from
an earlier version, which I think was 0.2.  I'm regenerating with 0.2 and
I'll see how it looks when it finishes.  If you want more details on what is
missing, let me know.  If you don't have time to look into it, I may have
some time to dig into the code tomorrow.

The stuff from the earlier version was looking pretty good. I did notice
that it doesn't seem to incorporate the address ranges.  I think you said
earlier that the original tiger attributes were being carried over so it
could be done later, but I don't see them in either the ways or segments.
It probably has to be tagged in the segments right?

I've got the ruby script to create excerpts from the converted files to a
decent state, and if you use it to cut the file into decent sized blocks,
JOSM is able to deal with them without any trouble.  I've attached the
script for anyone that wants to try it out.
