We remarked on several versions of GeoServer (e.g. 2.19.1, 2.18.2) on production platfroms (docker single replica), many tiles (256X256) which contain gaps when generated from GeoTiff EPSG:4326 reprojected to EPSG:900913. Details on GeoServer settings are in Tiles_with_gaps.png. The platform is: It happens on any GeoTiff file, with worldwide or less coverage, tri-bands or single-band. We were also able to reproduce gaps on non-tiled JPEG image, after a couple of dozens of WMS queries at different scale/coverage (see screnshot, obtained with geoserver/messir/wms?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&tiled=false&FORMAT=image%2Fjpeg&TRANSPARENT=true&STYLES&LAYERS=messir%3ATILED&exceptions=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A900913&WIDTH=1201&HEIGHT=1201&BBOX=696859.7838109258%2C766186.9103256974%2C1063499.499145654%2C1132826.6256604258). This is not related to client queries, as GeoServer generates as well tiles with gaps when using auto-generation of tiles via Tile Caching UI menu. |
