[gdal-dev] How to create TIFF with overview from a TMSserver ?

[Ralf Suhr]

Hi Jean-Claude,

now I'am sure we are talking about different things. A pyramid is the same 
raster in smaller resolution. You want a new raster tile from same tms server.

http://www.gdal.org/frmt_wms.html can be used as source. If the raster covers 
not the details of information you want, you can finetuning by changing the 
source-window and destination size.
