A geoserver 2.8.3 instance running with jetty 9.2 / jre7 fails to display a mosaic of tiff files (https://www.ppige-npdc.fr/opendata/ortho/2012-2013/DALLES_L93_RGB_TIFF/) without vertical artifacts when reprojecting from EPSG:2154 (Lambert 93) to EPSG:3857 I've setup a simple ol3-based viewer showing the behavior: https://ppige-npdc.fr/opendata/ol3.html Note that the artifacts only appear at the highest zoom levels (oversampling). Andrea said "Without touching anything, you can try to disable the "warp/affine" merging by passing this parameter to the JVM: -DENABLE_ADVANCED_PROJECTION=false" but this did not help fix it. |
