But I have a problem, the wms preview (ol2) of the geoserver and the ol3 visualisation have a blemish. 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: <br>EPSG:4326<br>extent: -25, 33, 40.25, 72 <br>resolution: 0.25<br><br>I use the same raster data stored in the geoserver directory and it works.<br><br>example<br>file-based<br><span class="Object" id="OBJ_PREFIX_DWT1520_com_zimbra_url"><a target="_blank" href="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">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</a></span><br><br>Geoserver PostGIS Raster<br><span class="Object" id="OBJ_PREFIX_DWT1521_com_zimbra_url"><a target="_blank" href="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">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</a></span><br><br>Thanks & Best regards<br><div>Christoph<br></div><br></div></div><br></div></body></html>
