<DIV><FONT face=Arial size=2>The section you have done so far looks great to
me. Seems to have the perfect amount of detail at the two levels that are
rendered. I don't see any tiles at zoom 9 or 8, I guess you haven't
rendered them yet.</FONT></DIV>

<DIV><FONT face=Arial size=2>I think the transparent layer had something to do
with IE not correctly displaying transparent .svg - although that could
have been from something different as I tried the link in IE7 and it worked
fine. Maybe it was earlier versions of IE?</FONT></DIV>

href="mailto:tiles@home">tiles@home</A> lowzoom method</DIV>
<DIV><BR></DIV>Folks<BR>I've been experimenting with a different method of
generating lowzoom tiles for <A
href="mailto:tiles@home">tiles@home</A>.<BR><BR>The approach I am taking is to
use the old tile stitching method coupled with a separate place name
layer.<BR><BR>The tile stitching starts with a layer of z12 tiles that are the
same as normal z12 tiles except the main roads are about 50% thicker and it
there are no place names. You can get a rough idea of what that will
look like by looking at the the current lowzoom tiles for the US - most of it
was rendered using the old stitching method before many place names had been
added. <BR><BR>I then propose a separate transparent layer for place
names. This potentially allows for multiple name layers for different
scripts and languages. I've heard some comments that transparent
layers are not a good solution - I'd be interested in understanding the pros
and cons of doing this. The alternative is to merge the transparent
layer with the lowzoom tiles using Image Magick, which would achieve the same
visual result but without the ability to dynamically switch the language.
<BR><BR>I've started doing some test renderings in the south of England,
although there is not really enough there yet to get a good feel for what it
would look like:<BR><A
