What resolution is Sentinel 1?
5 m
This instrument has a spatial resolution of down to 5 m and a swath of up to 400 km. The constellation is on a sun synchronous, near-polar (98.18°) orbit. The orbit has a 12-day repeat cycle and completes 175 orbits per cycle….Sentinel-1.

Which is better Landsat or Sentinel?
Both satellites showed the same performance in terms of accuracy, with area-adjusted overall accuracies of 96.7% and 95.7% for Sentinel-2 and Landsat 8, respectively. However, Landsat 8 mapped 36.9% more area of selective logging compared to Sentinel-2 data.
What’s the difference between lansat-8 and Sentinel-1A?
Because the Landsat 8 sensor is carrying a blue edge band (0.43 – 0.45 um), it is likely able to discriminate water/wetland features more effectively than the backscatter signal from Sentinel-1A. This would account for the differences in feature size, regardless of the on the ground cell resolution differences.
Which is better sentinel data or Landsat 8 data?
The free availability of Sentinel data, Landsat 8, and older Landsat archives constitutes an obvious advantage in the adoption of these data for long time series analysis at medium spatial resolution. 2. Materials and Methods
What is the resolution of Landsat 8 imagery?
Landsat 8 was launched in 2013, and its Operational Land Imager (OLI) provides high quality multispectral images at the resolution of 30 metres (15 for panchromatic) and a revisiting time of 16 days [2,3]. It aims to provide data continuity to the Landsat Earth observation programme, started in the 1970s.
Which is larger the oli or the Sentinel 2?
Sentinel-2A was launched in June 2015, and it is now operational, while the launch of Sentinel-2B is scheduled for 2017. The MSI has a very wide field of view (290 km swath width, which is significantly larger than the 185 km of the OLI).
