Hey Ben and others,
Yep, spot on, rendering hints but only related to zoom levels. I realise that
it's matter of opinion what roads to be rendered at what levels etc and why
rendering hints are not considered factual data and not preferred.
Changing the road classification is an option but are
What do you guys think?
It's non trivial to do it this way, but:
- Define a relationship between zoom level and number of ways/nodes
within the bounding box
- Sort the ways in a weighted fashion - roads first, land boundaries
second, etc
- Zoom level max, with 10 nodes to
You can change how mapnik renders by defining different styles for
different zooms.
Essentially with render hints you are saying that you would like this way
to look like a different type of way. If this does not map to some
verifiable attribute of the way then it becomes your preference.
Hi John,
Why would it be limited to just 1 purpose? Any rendering engine can take
advantage of these hints?

Thanks for the suggestions, I couldn't agree more for static rendering. However
this approach has some massive draw backs in terms of performance. Any
suggestions in this region?

Importance is of most interest. In regional areas where density is much lower,
rendering lower class roads earlier on in the zoom level would improve the
usability of the map much more.

Another idea was using routes to define the importance, what do you guys think
about this approach?

Hey everyone, have an idea about map rendering and want to get your thoughts.
One of the challenges is in rendering a useful map for recreational use is
displaying roads, tracks, trails and to some degree water lines at appropriate
zoom levels in more remote regions where the density is lower
Hi.
I think tagging for the renderer is a bad idea.
Essentially you are talking more about render hints, but I think that
becomes a matter of preference pretty fast. Especially when OSM data can be
rendered in a number of ways.
I think it is worth considering what about a road makes you want to
