Thanks for the answer and the suggestion. I will first try to warp the image and see the result. If I were to implement such an "extension" where would I need to start from? I am also thinking of adding some kind of batch import of files that can be queried based on name and time. It would be nice if it could be one store only that is queriable using cql for instance. It woudl be configured let's say via a database table with the lat/lon edges of each image stored as a polygon and the geotiff file name + some attributes such as time and name. Not sure if it makes sense? I can't be the only with such a need ;-)?
