Hi Steve.
I'm happy about that great client-side rendering, because there are
projects, where it could be extremely useful.
We have a web portal in planning stage with blind and visually impaired
people as the main target group.
Of course it's not useful to give a blind man a visual rendered map -
there we have to find other solutions, but for visually impaired people,
who are able to see images with very big countours or with higher or
lower contrast, or who have to avoid collisions between red and green or
something like that it is possible to render maps in a way, that they
are accessible.
The problem is: there is not one accessible map - there are many
variants, each useful for one or perhaps a couple of users.
Prerendering and storing a dozen maps would be waste of server and
storage capacity.
But rendering at client side, possibly giving the user a tool to
customize his rendering via mapcss would be great. There even two or
three seconds would not matter much in some cases.
regards
Peter

Hi all,
Glad to announce the first release of Kothic JS map rendering engine.
Incidentally, what are the goals for this cool technology? One thought
occurs that it could be integrated with other rendering platforms to
do on-demand rendering where the "real" tiles aren't yet rendered. But
for that to be useful, you'd probably need a server side renderer that
produced passably similar tiles...
I guess another huge benefit is allowing user customisation. Maybe
some site would serve up pre-rendered base tiles, with customised
Kothic JC tiles over the top.
The question also arises: how does Kothic JS relate to Halcyon? Both
are ECMAscript-based, MapCSS-compliant OSM renderers. I suppose Kothic
renders to tiles whereas Halcyon renders to native Flex sprites.
(Apologies for thinking out loud here...)
