<p>Hi all, I've been kicking around and further investigating ways of moving forward on this project/concept and have come to the personal conclusion that Mapnik provides a powerful base for building on.  For me there are several advantages including its Python base and cairo output options (for supporting various formats, including vectors).  </p>
<p>But also the XML based configuration files also seem relatively straightforward (easy for me to say ;-) ) and comprehensive enough for this project.  Of course there will likely be more specs we need to define to wrap up all our needs, but I think much of what we need is there.  I will do up a new/revised wiki page to show how I think we can build on this.</p>
<p>Any other pros/cons for using Mapnik as a base?  I figure rather than debate it for another year, we can focus on something and get issues clearly defined in that context.</p>
<p>By the way, Dane Springmeyer has built several useful utilities and a cool plugin for QGIS that allows you to style your layers, etc. and then view the Mapnik XML definition.  For those who want to check it out see Quantumnik:</p>
