Dear list,
I have merged 21 GeoTIFF images using GDAL utilities. Each image is the
result of merging 500 smaller tiles. I am using ImageMosaic in Geoserver but I
am getting a mosaic that contains white lines
What could be the reason behind having those white lines?
The commands that I used are: (recommended by Jonathan Mule)
gdalbuildvrt -srcnodata 255 -vrtnodata 255 -a_srs EPSG:27700 -input_file_list
tiff_list.txt mosaic.vrt
gdal_translate -of GTiff -co TILED=YES -co BIGTIFF=YES -co COMPRESS=JPEG -co
JPEG_QUALITY=80 -co BLOCKXSIZE=512 -co BLOCKYSIZE=512 -co
PHOTOMETRIC=YCBCR mosaic.vrt mosaic.tif
gdaladdo mosaic.tif -r average --config COMPRESS_OVERVIEW JPEG --config
JPEG_QUALITY_OVERVIEW 60 --config
INTERLEAVE_OVERVIEW PIXEL --config PHOTOMETRIC_OVERVIEW YCBCR 2 4 8 16
32 64 128 256 512
Thank you in advance
//Ammar
