Ciao Robert, here is the options you have in front of you IMHO: - ImageMosaic - You can do a bit of preprocessing and then use the ImageMosaic to handle the result automagically. Here is what I usually do:
- merge the initial files into larger chunks (up to 1/2 gb each) - add proper tiling and overviews to them - point the imagemosaic to the directory so that it can import them and build an index You can do the merge as well as the proper tiling and overviews with the gdal tools - ImagePyramid or ImageMosaicJDBC- You can use gdal_retile to build the pyramid out of the original tiles and then serve it with one of the two. Generally speaking, when the data size is the one we are talking about, I usually use approach 1 since in the end I have less files to manage. Approach 2 is used when we have much more data, but it is applicable anyway. Regards, Simone Giannecchini ------------------------------------------------------- Ing.
