The data is quite good and gets updated weekly. So... I don't want to
treat this as a one shot conversion. Updates should be part of my plan.
I've downloaded the SCL and converted it to lat/lon to use in xastir
http://www.xastir.org/
My current copy is a little old. I'll find my notes and get a fresh
copy.

Thanks. I'm an old Fortran programmer who's learned to hack together
Java, PERL. etc. but I've never tried reading/writing shapefiles or XML.
Should be fun to learn.
Initial import:
STRCLASS is the street class as defined by Clark County GIS (CCGIS).
1 for each STRCLASS in county shapefile
2 create scl.osm preserving attributes as ccgis: tags
3 extract working.osm from planet.osm with the same
bounding box as scl.osm
4 remove ways from scl.osm that are already in working.osm
(by comparing ccgis: tags)
5 use JOSM to replace TIGER ways with ways from scl.osm
6 upload changes
7 relax until planet.osm is updated
8 next STRCLASS
Step 1 may not be as simple as iterating through STRCLASS. The CCGIS
data doesn't clearly identify motorways. I plan to do these in the
first iteration by selecting on STRNAME. (That's what inspired step 4.)
Steps 2, 3, and 4 should be automated with a script.
Updates:
1 create scl.osm preserving attributes as ccgis: tags
2 extract working.osm from planet.osm with the same
bounding box as scl.osm
3 create add.osm, delete.osm, and change.osm by comparing
ccgis: tags in scl.osm and working.osm
4 review changes.osm with JOSM and upload
5 review add.osm with JOSM and upload
6 process delete.osm (but how?)
