Sorry for not responding sooner but this has a lot of good
information ->

There are postgis example scripts for generating points off a
centerline. I was involved in a project that used it. My only caveat
it's a lot of reading - but really good examples. <br>

Thanks. I did<br>
$ qgis numbers/chain_number.qgs<br>
and indeed saw your line with the four digit numbers on it.<br>
<br>
Actually I think I should avoid doing my project by hand via<br>
mouseclicks (Qgis), and instead learn PostGIS and write "batch
job" SQL script<br>
SELECT points WHERE each point is at 25 meter increments from the
start<br>
of road. Then print label on alternating side of road etc.<br>
Maybe I can accomplish the whole thing without a GUI.<br>
<br>
I'll send this to both lists.<br>
