Hi all,
I'm working with GeoServer on a project which is called IMPACT2C to
visualize the climate change of 2°C. GeoServer is a really nice tool for
displaying the maps with openlayers 3.
My problem is, that some of the raster data:
The extent of the wms jumps into the direction of panning for
displaying a full pixel. It is not possible to display a part of a
pixel. It is a low resolution raster dataset with this parameters:
EPSG:4326
extent: -25, 33, 40.25, 72
resolution: 0.25
I use the same raster data stored in the geoserver directory and it works.
We're using GeoServer 2.6.
Here are two examples of our test-server:
file-based
http://csc-gis01.x-t.at/geoserver/General/wms?service=WMS&version=1.1.0&request=GetMap&layers=General:test_raster&styles=&bbox=-25.0,33.0,40.25,72.0&width=552&height=330&srs=EPSG:4326&format=application/openlayers
Geoserver PostGIS Raster
http://csc-gis01.x-t.at/geoserver/wp2/wms?service=WMS&version=1.1.0&request=GetMap&layers=wp2:extreme_precipi_current_mean&styles=&bbox=-25.0,33.0,40.25,72.0&width=552&height=330&srs=EPSG:4326&format=application/openlayers
<http://csc-gis01.x-t.at/geoserver/wp8/wms?service=WMS&version=1.1.0&request=GetMap&layers=wp8:pm25_current_mean&styles=&bbox=-25.0,33.0,40.25,72.0&width=552&height=330&srs=EPSG:4326&format=application/openlayers>
Here are the example of the live-Version of the IMPACT2C web-atlas with
the pixel jumping problem:

If you zoom to Italy, you can see, that the pixels of the map are jumping.
Thanks & Best Regards
Carina
