They way I have created my pyramid with this data is as follows (and if
somebody can improve it, please tell me)
Take the OS *.tif files and copy them into a directory for each OS Grid e.g.
SD, SO, SH etc
Add the relevant world files to each directory.
Create a 'prj' file for each tif file. It is always the same so I create a
pro.prj file and with a bit of scripting, find all the *.tif files and copy
prj.prj to the same name, changing the extension to pro, so I end up with three
files for each tif (sh67.tif, sh67.prj, sh67.tfw)
Now I run this script (quick, dirty, no comments and no apologies for that)
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
(As I understand it that creates GeoTIFFs from all the tifs and adds overviews.)
I then create the pyramid with;
#!/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=256'
-co 'BLOCKYSIZE=256' -s_srs EPSG:27700 -targetDir pyramid --optfile
../tiles$thedir.txt
Not sure pif that helps?
