Hi Simone, Thanks for the information. The best for resampling was "Average", as it produced the smoothest image for the pyramids, at least with all of the Ordnance Survey products I've processed. Number of Tiles: I think some sort of guide may be useful. I appreciate the numbers used will have t

Ciao Jonathan, I don't know about FME therefore I cannot comment on how to do such things with it. I hardly believe many people on this list (as well as on other OS oriented lists) will know it much. This to say that most intructions you'll find will be oriented towards OS tools like GDAL utilities

This might not be exactly what you want but my workflow (Under Linux) is 1) Take the raw TIF images 2) Add a .PRJ file for each image 3) Add the World file for each 4) Run gdal_translate for each file for file in `ls *tif` do gdal_translate -of GTiff -co "TILED=YES" -co "COMPRESS=DEFLATE" -co "BL

Hi list, Following this up, I've decided to go the GeoTIFF/BigTiff route with inner tiling and overviews based on Andrea's document. But unfortunately there doesn't seem to be any documentation on the GeoServer pages about this stuff. I've never used GDAL before and generally avoid the command line

Hi Jukka, Thanks for the information. Relating to the TIFF's, I'd still prefer to use one single tool (specifically FME) for tile/image creation. FME can create pyramids, but not as part of a GeoTIFF. So I can create separate TIFF files and tile them if necessary too (either internal tiling or reg

Hi, The idea is that the GetCapabilities message includes all the necessary information about the configured gridsets which are supported by the server. After that It is up to the client software or programmer to know what to do next. For example uDig knows automatically how to deal with WMS-C

Hi Arne, Thanks for the reply. I get what gridsets do (further clarified by your reply), I don't understand how to use them. What other parts of GeoServer do they interact with? Or what parts of the client software? And how do you get the client software to use the same gridsets? The documentation

If you want to have efficient caching it is crucial that clients ask for the tiles that you have already generated. Basically they need to know the grid that you are basing your tiles on (origin of the grid, size of each tile in terms geographical extent and in terms of pixel size). And you nee

Hi List, A few generic questions. First: What are gridsets actually for? I know how to create them (the documentation is very good for that), but I can't figure out what they're for. Second: I have a number of large rasters in JPEG2000 format (up to several GB in size). GeoServer can't access the
