I have hundreds of GB of somewhat small tif files. Here is gdalinfo of one of them:

I used gdal_retile.py with the following command line:

gdal_retile.py -v -r bilinear -levels 4 -ps 2048 2048 -co "tiled=YES" -targetDir pyramid --optfile files.txt

I then create an Image Pyramid store in Geoserver and set multithreading to true, and USE_JAI_IMAGEREAD in the layer. When I go to Layer Preview and click on KML it opens in Google Earth. When I zoom in, it takes a very long time to render, and sometimes it times out and gives me various errors.

Currently I built the Image Pyramids with only 30 or 145 of those tifs to see if maybe it was because my data set was so large, however I get the same performance with those smaller sets.

What am I doing wrong?

Here is a picture of one error I am getting:

I also get an error that just says "Error when parsing file"

Thanks!

Actually I think I found my own mistake. I was making 145 image pyramids apparently instead of just one image pyramid. Calling gdal_retile.py multiple times on multiple files creates multiple image pyramids. You need to use the --optfile option to send it a list of files to make only one image pyramid. – Derek H.

Not only that, gdal_retile.py wont accept filenames with spaces and/or hyphens. It also needs to the tifs to be converted to north-up or it crashes. – Derek H. Nov 15 '12 at 17:58
