<DIV><FONT face=Arial size=2>I've rendered and uploaded two tiles 74,96 and
74,97. They're the southeastern part of Pennsylvania in the US.
These tiles cover Allentown and Philadelphia so they're fairly dense. I'm
not sure that I did everything properly though since the new lowzoom tiles are
pretty sparse and as you zoom in from 8 - 11 things get kinda weird. There
are random tiles missing (or blank?) and there's really no solid detail until
you get down to z12.</FONT></DIV>

<DIV><FONT face=Arial size=2>Can someone have a look and tell me if I'm doing
something wrong or if this is the expected output? Maybe I'm not fully
understanding the new lowzoom method...</FONT></DIV>

Re: [Tilesathome] Lowzoom rendering</DIV>
<DIV><BR></DIV>The new lowzoom method uses a different process.
<BR><BR>The first step is to generate a lowzoom caption-only layer for
z8-z11. There's no layers.conf in svn that will do this at the
moment, but the one I use is included below.<BR><BR>You then have to
upload this layer and wait until it has be processed by the <A
href="mailto:t@h" target=_blank>t@h</A> server. Currently the next
step expects to be able to download the caption layer, and you don't get
up-to-date results unless its there.<BR><BR>The second step is to run the
tools/lowzoom/lowzoom_composite.pl script using the following
arguments:<BR><BR>lowzoom_composite.pl x y 8 12 tile captionless
caption<BR><BR>This will read the z12 captionless base layer and the
caption layer from z8 to z11 and composite these together to create the
tile layer which is what ultimately gets uploaded.<BR><BR>This approach
currently works best for z8 - z11, there is a projection bug which causes
captions to be misplaced at levels lower than z8, so usual tilestitching
method is still the best approach for z0 - z7.<BR><BR>There's a summary of
the approach here: <A
