[Carto] Building on Mapnik

Dear Tyler

It is seems  you have been involved in a very deep research. It's sounds fine because I started to feel no so comfortable with this project due to the lack of activity.

Now I haven't got enough time for review MapNik entirely but I will try to find space and give a more professional opinion.

The little I know about that initiative is it has a nice rendering system that it is consistent with this project.

My best regards

Asunto: [Carto] Building on Mapnik

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).  
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.
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.
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:
