Description

GeoServer 1.6.4 does not render my point layer correctly. There seems to be some type of coordinate shift occurring. My feature type info.xml is identical during my tests with 1.6.3 and 1.6.4

The details:
datastore = postgis
SRS = 4326
native bbox ~= -179.9, -72.4, 180, 88

PDF request URL:
http://localhost:8080/geoserver-1.6.4/wms?bbox=-197.89500961303665,-80.46500167846679,197.99500045776364,96.96500167846679&styles=&Format=application/pdf&request=GetMap&version=1.1.1&layers=topp:buoyobservation&width=800&height=336&srs=EPSG:4326

I am using the map preview demo page to test. The SVG link renders in FireFox as expected, but the OpenLayers and PDF links do not show a correct rendering.

I've attached two example PDFs – one showing how the data set looks like when it is served from 1.6.3, the other when it is served up from 1.6.4.

Gah, managed to reproduce something similar to it. Happens with postgis datasource (could not reproduce with shapefiles) and only with point symbolizers.

Confirmed, this is a side effect of another bug fix. This is pretty serious, I fear we'll have to redo the gs1.6.4 and gt 2.4.3 releases because of this one...

Ryan, I've attached a modified renderer that should fix the problem. To try it out, you should stop geoserver, go to the geoserver/web-inf/lib directory, remove the gt-renderer-2.4.3.jar file and replace it with the one attached. Then start geoserver and see if it fixes the problem for you.

I've confirmed in my environment that gt2-render-2.4-SNAPSHOT.jar fixes the problem.

Fixed on 1.6.x and trunk (as effect of fixing geotools)

I had the same problem, and I applied the fix that seems to work, but sometimes I get a blank image back.

This URL returns a blank image: http://my_geoserver/geoserver/wms?service=wms&TRANSPARENT=true&LAYERS=ds:mylayer&REQUEST=GetMap&SERVICE=WMS&FORMAT=image%2Fgif&STYLES=&HEIGHT=1000&VERSION=1.1.1&SRS=EPSG:25832&WIDTH=1000&TRANSPARENT=TRUE&EXCEPTIONS=application/vnd.ogc.se_inimage&BBOX=600000,6000000,1000000,6400000

Panning 1 km north & east returns a image as expexted: http://my_geoserver/geoserver/wms?service=wms&TRANSPARENT=true&LAYERS=ds:mylayer&REQUEST=GetMap&SERVICE=WMS&FORMAT=image%2Fgif&STYLES=&HEIGHT=1000&VERSION=1.1.1&SRS=EPSG:25832&WIDTH=1000&TRANSPARENT=TRUE&EXCEPTIONS=application/vnd.ogc.se_inimage&BBOX=601000,6001000,1001000,6401000

The geoserver log-file (with debug) does not show any different processing for the 2 requests.

My environment: RHEL 5, postgresql-8.3.1, tomcat-6.0.16, geoserver-1.6.4a patched with gt2-render-2.4-SNAPSHOT.jar

Tried it out, could not spot any issue, only one visible point gets renderer in both cases, and it's the correct result. The points above have 6 out of 8 geometries at the same location, and the remaining two have the same location as well.

select id,astext(geometri) from byggesag;
id | astext
---+----------------------
1 | POINT(466276 6151398)
3 | POINT(723182 6183914)
5 | POINT(466276 6151398)
6 | POINT(466276 6151398)
7 | POINT(466276 6151398)
8 | POINT(466276 6151398)
9 | POINT(466276 6151398)
4 | POINT(723182 6183914)
(8 rows)

Your bbox filter BBOX=600000,6000000,1000000,6400000 captures only rows 3 and 4, and only one points appears on the screen in both images, I'm not getting back any blank image...
Tried with both GeoServer 1.7.x series and 1.6.x series. It may be somethign that has been fixed already, don't know. Maybe try out a nightly from: http://gridlock.openplans.org/geoserver/1.6.x/
