and further to my example, the gaps and black areas started appearing after GeoServer upgrade to 2.1.1 which I did just after a Java upgrade to 1.6.0_26 (on Ubuntu 64-bit server 10.04 LTS).
If I try to revert to 2.1.0, Geoserver starts then crashes (I thought it should revert easily back to previous minor version?) so I've had to go back to 2.1.1. This is how I generated the images that go into my ImageMosaic, which was working in 2.1.0 on previous Java version, so I doubt it's a projection problem: gdalwarp -s_srs "+proj=tmerc +lat_0=0 +lon_0=19 +k=1 +x_0=0 +y_0=0 +ellps=WGS84 +datum=WGS84 +units=m +no_defs" -t_srs "EPSG:3857" -r cubic -multi -tr 0.5 0.5 -of GTiff file_a /tmp/file_b then gdal_translate -co "TILED=YES" -co "COMPRESS=JPEG" -co "PHOTOMETRIC=YCBCR" -co "JPEG_QUALITY=75" -projwin ulx uly lrx lry /tmp/file_b file_c then gdaladdo -r average --config COMPRESS_OVERVIEW JPEG --config PHOTOMETRIC_OVERVIEW YCBCR --config INTERLEAVE_OVERVIEW PIXEL file_c 2 4 8 16 32 64 On Tue, 2011-08-09 at 05:44 -0700, AndyC wrote: > For further infomation I have also tried the following; Converting jpg > to tiff files, creating new .tfw files and gdal_translate to geotiff > with the same gaps appearing.
