What is Sentinel-2 imagery?
Sentinel-2 is an Earth observation mission from the Copernicus Programme that systematically acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters.
Is WorldView-2 still operating?
WorldView-2 is an imaging and environment-monitoring satellite from Maxar of the United States which launched on 8 October 2009 and remains operational. It is the follow-on spacecraft to WorldView-1.
What can I monitor with Sentinel-2?
As well as monitoring plant growth, the Sentinel-2 instruments can be used to map changes in land cover and to monitor the world’s forests. It will also provide information on pollution in lakes and coastal waters.
Is Sentinel-2 data free?
All Sentinel-2 data products are provided free of charge to all data users, including the general public, and scientific and commercial users under the terms and conditions prescribed by the European Commission’s Copernicus Programme.
Is Sentinel-2A lidar?
Lidar surveys and Sentinel-2 satellites are used to map shallow bathymetry. The capabilities of SDB for recursive mapping at 10 m resolution are evaluated. The composited SDB model allows monitoring over environments with transient turbidity. Detection change is identified at two dynamic inlets in North Carolina (USA).
How many WorldView satellites are there?
About WorldView Series Owned by MAXAR, the first three satellites in the series are currently operational, and they have been supplying imagery since 2007. WorldView-2 launched in 2009, as a follow-on spacecraft to WorldView-1.
How many spectral bands does Sentinel 2 have?
13 spectral bands
SENTINEL-2 carries an optical instrument payload that samples 13 spectral bands: four bands at 10 m, six bands at 20 m and three bands at 60 m spatial resolution.
How do I get Sentinel 2 images?
You can obtain Sentinel 2 data from the ESA and from the USGS. Users must register for free access to data at either site. Currently ESA distributes Sentinel 2 data in entire swaths.
How long has Sentinel-2 been around?
The first Sentinel-2 satellite was launched in June 2015.
Is Landsat LiDAR?
Given the continued demand for Landsat imagery and the growing supply of ETM+ data, Landsat 7 is a logical choice for integration with lidar sample data.
Does Landsat have LiDAR?
Combining satellite sensor, LiDAR data Accessing data from Landsat 8 and the Sentinel-2A and 2B satellites makes it possible for Oliveira to retrieve images of the Brazilian Amazon every three days.
What is the resolution of military satellites?
“According to an estimate by the private Federation of American Scientists (FAS), three satellites operated by the US National Reconnaissance Office (NRO) have resolutions as sharp as 10 centimeters (3.93 inches) — in other words, the satellites can discern a softball-sized object from several hundred miles away.”
