I've been messing around with that, I'll try some more. Thanks.

I have had data with native and declared SRS 900913, geoserver 2.1.1
that was cut off when viewing through GWC and fine when viewing with
WMS. If I remember correctly as I zoomed in I could not view some
easternmost or southern most tiles. I never went to back to PostGIS to
view the bbox coordinates.
What I did was increase the MaxX and MinY native bounding box
coordinates and recomputed the Lat/Lon bounding box. After tweeking
the values all my data was displayed through GWC.
I realize that may not be a totally satisfying answer, but it solved
my problem.

*Subject:* Re: [Geoserver-users] bbox and tile issue
MaxX on the config page says -76.565315246582. So does the bbox
parameter in the url. The bbox of the openlayers preview also
cuts-off the easternmost data. However I can drag the map to see the
rest of the data, and the easternmost data point is consistent with
the bbox report when I go directly into postgres. I then think GWC
uses this incorrect bbox when generating tiles. If I type in the
correct bbox into the layers config page (instead of using "compute
from data") then bbox is correct on the preview page (and in the
url), but GWC still does not generate correct tiles.

Sorry - so your layer config page says:
·Min X[ ]
·Min Y[ ]
·Max X[ ]
·Max Y[ ]
and when you click on layer preview the url at the top has a
parameter like;
bbox=something,something,-74.9etc,something
?
What is your native and declared SRS? Both 4326?

Hi Toby,
When using WMS all points are OK. I'm using the built-in GWC.
Points do not have labels.
Geoserver reports the eastern edge of the bbox as
-76.565315246582. PostGIS says it is -74.924247214709, which is
also what I get when I view the WMS in the layer preview. This
leads me to believe that the bbox reported by geoserver is
incorrect, and then it is using the incorrect bbox to cut-off the
data on tiles that are east of the incorrect value.
Thanks,
Steve

Just some clarity;
Are you saying that when you preview the layer as WMS all the
points are there ok?
If so, then the BBOX in the layer config page must be correct,
and this isn't the issue.
Are you using the built in GWC in geoserver? Do your points
have labels?

Hi All,
I'm using postgres 8.4, postGIS 1.5, Geoserver 2.2. I have a
point
layer with 143,500 records. It looks great with regular WMS.
However
when I use tiles some of the data are missing. I can see in
the "edit
layer" page that the bounding box ("compute from native
bounds") is not
the same as that when using ST_extent in postGIS---the GS box
is ~1.7
deg lon smaller--and the missing data are from the area that
is the
difference between the two. I tried editing the layer page
with the
postGIS bbox and then emptying the tile cache, but still no
change; all
data east of smaller bbox are missing.
Any thoughts?
Thanks,
Steve
