I have a set of 100 tiles (UK Ordnance Survey data).
I have created an image pyramid, created a store and added a layer.
When I view it, via GeoServer preview, it all looks fine until I stat to zoom
in. At a certain zoom level (The scale reads 1:87k) some of the tiles get drawn
as white.
So tiles are there at 1:174k, not there at 1:87k and back again at 1:44k
When I look in the logs (catalina.out) I see the many lines with a line saying;
...
Caused by: java.lang.IllegalArgumentException: All source images must have the
same number of bands.
…
The source images all seem to have the same number of bands (1) and I do the
following to create the pyramid
#!/bin/bash
echo -n Working on
pwd
mkdir out
for file in `ls *tif`
do
echo -n Working on $file
gdal_translate -of GTiff -co "TILED=YES" -co "COMPRESS=DEFLATE" -co
"BLOCKXSIZE=512" -co "BLOCKYSIZE=512" -a_srs "EPSG:27700" $file out/$file
done
mv out/* .
rm -fr out
for file in `ls *tif`
do
echo -n Working on $file
gdaladdo -clean $file
gdaladdo -r average $file 1 2 4 8 16 32 64 128
done
Followed by
#!/bin/bash
export thedir=`pwd`
export thedir=`basename $thedir`
echo $thedir
mkdir pyramid
ls *tif > ../tiles$thedir.txt
gdal_retile.py -v -levels 9 -ps 2048 2048 -co 'TILED=YES' -co 'BLOCKXSIZE=512'
-co 'BLOCKYSIZE=512' -s_srs EPSG:27700 -targetDir pyramid --optfile
../tiles$thedir.txt
I can post more of the log if required.
I am hazarding a guess it is something to do with the version of Java. Do I
need to go back to 1.6.*
