<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
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>
