[Geoserver-users] Mosaic of 842 geotiffs

GeoServer GeoServer User

I've been doing more or less the same thing and it did the trick for me.

Instead of transforming to Geotiff with gdal_translate, I suppose.
I do the complete process with gdal_retile, this will retile your data
to uniform tiles (you can specify width, height and resolution), if you
use the option -co "TILED=yes" it will create internal tiles in your
tifs, and it will create your index too. Then I run the gdaladdo with
just 4 to 5 levels.

Hope it can help you.

Subject: [Geoserver-users] Mosaic of 842 geotiffs

Hello,

I try to create a mosaic of 842 of files. The files are originally tif

+

tfw
pairs, which I transform in geotiff and create 10 levels of overviews

for,

using gdaladdo. Then I make a mosaic of all the files using

gdaltindex.

Maybe a first problem : if I check the pixel size values of my

geotiffs in

the lines GeoTransform with gdalinfo, I see values going from 0.666648

to

0.666680, average is 0.666665. The x value is not necessarily the same

as

the y value. In my .properties file, I set 0.666666,0.666666 as my

first

level. Is there a problem with the different values ?

When I load the layer, I see in the logs that 797 mosaic images are
loaded,
then I get a
WARN [geotools.rendering] - operation "ImageRead" requires parameter

at

index 0 to be non-null.
java.lang.IllegalArgumentException: operation "ImageRead" requires
parameter
at index 0 to be non-null.

Any idea if the number of files or the different values of resolution

my
geotiffs ?

Ciao Pedro,
sorry to bother but, can I ask you to sum up what you did in the GeoServer wiki?

Well,
that would be great, I might do that myself, in which case I will ping
you. ( I doubt I will find time in the near term though :-))

I tried Pedro's method on my data but gdal_retile process was killed by my
OS, taking too much swap space (max 2GB). I was trying to retile my 842
geotiffs, each 12000 x 7500 pixels, to 48000 x 30000 pixels for the output
files.

I'll try the pyramid method, didn't have a look at it yet.

gdal_retile : I tried to lower the image size not to fill my swap space,
increasing the number of images, it worked for about 10 output images, then
I got a seg fault. This was the command I used :

gdal_retile.py -v -of Gtiff -co "TILED=yes" -ps 24000 15000 -tileIndex
retiled -targetDir
/opt/tomcat-6.0/webapps/geoserver/data/coverages/rasters/top10r/retile
*_map.tif

PyramidBuilder : as I'm on a server without a GUI, I couldn't use Maven and
eclipse. I downloaded the geotools jar files and tried it on the command
line but all I got was this :

tomcat@anonymised.com:/opt/geotools-2.5.1$ java -Xmx1000M -classpath

I tried Pedro's method on my data but gdal_retile process was killed by my
OS, taking too much swap space (max 2GB). I was trying to retile my 842
geotiffs, each 12000 x 7500 pixels, to 48000 x 30000 pixels for the output
files.

I'll try the pyramid method, didn't have a look at it yet.
