I contacted the guys at MapOSMatic to give some feedback. I felt that while it was a superb tool at some zoom levels (eg outputting a map of Makati area), that it lacked a bit when you zoomed in closer, or out further. 

Here is a reply from David Mentre at MapOSMatic. Development is evidently under way, and it looks set to get even better. I wish I was a coder ... 


Hello Jim,

Many thanks for your very positive feedback!

In fact, we are using a fixed zoom level (I can't remember which one right now).

Our intent was to provide a certain level of details on all maps,
whatever is the zoom level of a map. But we agree that this approach
might not satisfy all use cases.

I have added a task for this, so the feature wish is recorded:

Regarding the choice of various items, we are working on it, we a set
of predefined stylesheets. You can see an example of it on our
development version: http://dev.maposmatic.org/

Of course! :-)

We have also a mailing list, an IRC channel, etc. All patches are welcome! ;-)

As I said, the next version of MapOSMatic will have a set of
predefined stylesheet. But even with current MapOSMatic code, if you
install it on your own computer you can tailor the Mapnik rendering
stylesheet at will.
