Dear Amiala,
I thinkl you are on the right track.
A few hints:
-1- I would make the size of the tiles even bigger than 1024x1024.
Make sure to have them internally tiled. In the presentation I
attached there are hints on how to do/check that
-2- Yeah, the less files in folder, the better. 1 will help with that
That said, I would like to see the final properties files that
geoserver generates in the root foolder as well as in the top children
folder to understand the resolution structure for these layers.
Regards,
Simone Giannecchini

Ciao Simone,
What's a great presentation! I found it very useful!
I just need to clarify some issues:
I have:
- 13 levels of ArcGIS Cashed data in .bundle format on the disk. The bigest
lever is 18 GB, in total there is 25GB.
What I need:
- Geoserver Image Pyramid (with 13 zoom level and fast serve for user)
What I already did:
1. I converted ArcGis data (accesing it by url as a tile) from .png to
.geotiff with .jpeg compression using .geotiff lib (I didn't manage to do it
for 2 biggest layers - too many tiles)
2. I used geoserver ImagePyramid plugin (from Web Interface) and create
ImagePyramid.
Problems: laoding map and zooming (in/out) are too slow
What I think after reading your presentation:
1. I need to use UseDirForEachRow option. Now in the last folder I would
have more than 16 000 000(!) tiles
2. I need to make bigger tiles (2048x2048 for example)
My questions:
1. Do you think I am on the right way now (2 previous items)?
2. If I use "UseDirForEachRow" I will have 4000 folders with 4000 tiles each
for the last level, will it help? or it is still too much and I have to find
other way.
Thank you again,Simone!
