I have to compute sea wave forecast for large period of time. Land information is of no use here.
Is there any file format that allows to not store no-data/fill values for land area to reduce file size? Chosen format for now is NetCDF, but it can be changed.
Other idea is to store only sea point values in binary file and write or read it using land sea mask. But it would probably have to be some custom data format.
Is it good or common practice to not include no-data points information in file?
