data sets indexed and being served by MapServer for the entire US, so I'm rather
certain this scenario can be made to work. You might want to think through
your application design, however, since simply trying to index everything is not
necessarily the best solution. The primary goal of performance tuning
should be to make sure that data that won't be used in the output map isn't
touched or even considered wherever possible.</FONT></SPAN></DIV>

with tiled layer<BR></FONT><BR></DIV>

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I’m using Mapinfo files for vector
data, some of the layers are county-based. I created tiled index layers
for these county-based layers (my demo consists of four counties in North
Carolina) using the ogrtindex utility. When the map straddles the border
between two counties, the tiled layers do not appear in one of the counties (the
roads, etc. stop at the county border). Panning either direction so that
the map no longer straddles the border makes the missing layers reappear.
I assume this is a bug in GDAL/OGR or mapserver (CGI version 4.4.1). Has
anybody else seen this problem? Is there a workaround, or do I need to
rethink my use of tiled layers? The application will need to cover the
entire <st1:country-region w:st="on"><st1:place
w:st="on">U.S.</st1:place></st1:country-region>, so effective indexing of the
data is a requirement.<o:p></o:p></SPAN></FONT></P>
