After signing in, filters can be adjusted to isolate specific datasets. For InSAR analysis, Sentinel 1 (A or B) SLC datasets are required. Selecting data with short temporal ranges (6 day) is appropriate hazard assessments or rapid land cover changes. Sentinel 2 measures with a multispectral sensor and is a good supplement to any analysis done with the Sentinel 1 imagery. If desired, a cloud cover threshold can be selected to limit the product search to imagery that is below a certain percentage of cloud cover. This is an especially useful parameter to specify when looking for imagery in tropical regions where cloud coverage is often a problem in sensors which imager along regions of the electromagnetic spectrum that have short wavelengths (i.e. visible and infrared). | After signing in, filters can be adjusted to isolate specific datasets.
