How to Create a Subset of a Sentinel-1 Product

Source: ASF Staff


At times, the area covered by a downloaded product is much larger than the area of interest. Processing a large image requires more time and computer power than what is necessary. Creating a subset is an easy way to improve efficiency in workflow and preserve resources. This recipe will go over the basic steps to get started in the Sentinel-1 Toolbox and to create a subset of your desired area of study.
