Thanks for the response, Dane.
I don't know much about proj4 strings, but I don't think they'll
help in my situation, because I want to run a separate computation
for each point and recalculate its position based on some additional
data I have coming out of a database. I'd really like to just be
able to call my own Python function, pass in lat/lon and return a
new lat/lon. Can I do that with the srs parameter?
Honestly in can't say. I think I'd need more specific info.
Thanks,
Drew

just set the map srs to the custom proj4 string you'd like to
reproject everything into, and Mapnik+Proj4 should be able to do the
rest.

I'm rendering maps from OSM data (coming from Postgres; I can't get
the OSM plug-in to work with XML files). I'd like to run a simple
Python function on the OSM data to transform the coordinates each
time a map is rendered. This isn't a conventional projection, so I
don't know if I can use Proj4. Can anyone recommend a way to call a
function on the data that gets returned from the Postgres query?
Thank you,
Drew
