What is the resolution of Sentinel-1?
Operational/acquisition modes Sentinel-1 has four operational modes: Strip Map (SM) Mode features 5-by-5-metre (16 by 16 ft) spatial resolution and an 80 km (50 mi) swath. Interferometric Wide Swath (IW) Mode features 5-by-20-metre (16 by 66 ft) spatial resolution and a 250 km (160 mi) swath.
What is the difference between Sentinel-1 and 2?
The first Sentinel-1 satellite was launched in April 2014. The objective of Sentinel-2 is land monitoring, and the mission will be composed of two polar-orbiting satellites providing high-resolution optical imagery. The Sentinel-5 UVNS instrument is a spectrometer carried aboard the MetOp Second Generation satellites.
What is the difference between Sentinel-1A and 1B?
Both Sentinel-1A and Sentinel-1B share the same orbit plane with a 180° orbital phasing difference. With both satellites operating, the repeat cycle is six days. In particular for interferometry, Sentinel-1 requires stringent orbit control.
Is there InSAR processing in Google Earth Engine?
The answer is no. It is not possible to do any InSAR processing with Google Earth Engine, at least now. You might check ESAs geohazard TEP for cloud-based insar processing or COMET Services. (Also check this link ) There are some more efficient/flexible python-based InSAR toolboxes.
How does Sentinel-1 work in Google Earth Engine?
Sentinel-1 collects C-band synthetic aperture radar (SAR) imagery at a variety of polarizations and resolutions. Since radar data requires several specialized algorithms to obtain calibrated, orthorectified imagery, this document describes pre-processing of Sentinel-1 data in Earth Engine.
What can be detected by the Sentinel-1 SAR platform?
Detected changes, both short- and long-term, can be related to landscape dynamics and human activity. A basic knowledge of the Sentinel-1 SAR platform is assumed on the part of the reader, at the level of the ESA User Guides.
How long does the Sentinel 1 mission last?
The Sentinel-1 missions of the ESA provide a fantastic source of weather-independent, day-or-night Earth observation data with repeat times of the order of 6 days.
