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
Those are all good suggestions, I feel kind of silly asking now because the
solutions all seem painfully obvious. Thanks for putting up with me ;)

Thanks. I did
$ qgis numbers/chain_number.qgs
and indeed saw your line with the four digit numbers on it.
Actually I think I should avoid doing my project by hand via
mouseclicks (Qgis), and instead learn PostGIS and write "batch job" SQL script
SELECT points WHERE each point is at 25 meter
OK I found
http://postgis.refractions.net/documentation/manual-svn/reference.html#Linear_Referencing
So I should:
1. Learn how to import my vector roads from .kmz into postgis. (I'll Google
that.)
2. Use http://postgis.net/docs/ST_Length.html to get the length (L in meters)
of each
of my

OK I found that. But then the whole layer becomes the selected color to
the entire edges of the planet. And there is no way to undo short of
closing qgis and not saving. As CTRL+Z does not work.
Hi Dan,
This is not true - you can switch to map units everywhere there is a
distance property.

OK I have determined that everything in the Layer Properties menus
(style etc.) I should NOT use, because they are all millimeter based
(and will not change with what scale I print the map at.) And I should
instead look at the degree and meter based plugins like Qchainage.
Thanks. The idea is every 25 meters there should be a (proposed) house
number (location) on the left, then one on the right, left, etc.
Making for a total of 20 + 20 = 40 per kilometer.
Sort of like what I did with GRASS years ago

Hi Dan,
Interesting problem.
Are these regularly spaced or should they appear at given vertices of
the input vector line?
I was thinking that maybe one could use a marker line, with dynamic font
markers - but unfortunately there are no "per feature iterators" or
"counters" available in the
