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
