I am trying to use the GDAL command line utilities to format 2 million images (geotiff) of variable size in a form that can be uploaded to geoserver to be served via WMS.
I am having problems determining what is the best method to format the data i.e. do I pyramid the whole set using gdal_retile.py? do I build a VRT for 10k images, use gdal_translate to create an internally tiled image then gdaladdo to create overviews? I can then use gdaltindex to create a shapefile for all the resulting images and create an ImageMosaic layer in geoserver. What do people suggest is the best method to do this firstly from a GDAL point of view, then integrating the results into geoserver? Also, how do I add another million images in a months time? Do I have to go through the whole process all over again or is there a way I can append data? Thanks.
