SIS has some write capability, but it is currently not easy to open a DataStore in write mode. We propose to add the following convenience method in DataStores:
public static DataStore openWritable(Object storage, String format);
It would open the specified storage (file, URL, JDBC connection, etc.) in write mode. The format argument would be used for selecting a format if the file does not already exist.
After a convenience method has been added, we should update the "how to" page at https://sis.apache.org/howto/resample_and_save_raster.html.
