Subsetting

From Wikipedia, the free encyclopedia

Subsetting is a concept used in research communities (e.g. earth sciences etc.) to describe the process of retrieving just the parts of large files which are of interest for a specific purpose. This occurs usually in a client -- server setting, where the extraction of the parts of interest occurs on the server before the data is sent to the client over a network. The main purpose of subsetting is to save bandwidth on the network and storage space on the client computer.
