Download Sentinel-1 and Sentinel-2 Satellite Data
If you need to download Sentinel satellite information, at that point you’ve gone to the opportune spot.
One of the most energizing advancements in remote sensing as of now is the European Space Agency’s Copernicus Program.
Copernicus’ six Sentinel satellites collect thorough photos of our land, sea, emergency response, atmosphere, security, and climate change to comprehend the wellbeing of our planet.
Until as of late, this information has opened up to the general population at no expense
Sentinels Scientific Data Hub
In 2014-15, Sentinel-1 and Sentinel-2A were effectively propelled from Europe’s Spaceport in French Guiana.
One Sentinel scene after different, information has been turning out on a user interface called the Sentinels Scientific Data Hub.
It’s presently accessible for people, in general, to get to.
In any case, you should jump through several bands before you can get your fingers on it.
Follow these means to download free Sentinel satellite data:
Stage 1 Create a User Account
Go to Sentinels Scientific Data Hub.
In the upper right of the web map, click the SIGNUP button.
Insert valid entries for your name, email, and location. Click register. Validate your email.
With a couple of snaps of the mouse, you’ve access ESA’s Sentinel data.
Stage 2 Select Your Area of Interest
Where is your study area?
Using the SEARCH CRITERIA content box in the upper left, type in your general vicinity of intrigue.
From here your quest will yield results for all the Sentinel satellite data available.
Sentinel-1 (Synthetic Aperture Radar C-Band) areas are delineated in red. Sentinel-2 (multi-unearthly information) areas are delineated in green.
Stage 3 Download Sentinel Data
Now, that we have our user account created with our study area defined – all we have to do is sift through the results and download our chosen Sentinel data.
As we are working with large data sets, you will have to be patient with download speeds. It’s easy for the server to timeout during the download.
Select the product you want to download. S1A is Sentinel-1A. S2A is Sentinel-2A.
Below the product thumbnail that has the download URL. This is what you want to clip in order to download your chosen Sentinel data.
What’s Next?
After you download Sentinel satellite information, odds are that you are going to need to show it in the obvious range. This is actually how our eyes see questions around us.
Each image is separated by its respective spectral band. See our table below for the spectral bands of Sentinel 2. Sentinel 2B will be identical to Sentinel 2A.
What are the Spectral Bands of Sentinel 2A and 2B?
We’ve listed below, the spectral and spatial resolution of Sentinel 2A. There are 13 bands in total. Four spectral bands have a 10-meter resolution. Six bands have a 20-meter resolution. And the remaining 3 have a spatial resolution of 60 meters.
Here are the spectral band details for Sentinel 2A:
| Band | Resolution | Central Wavelength | Description |
| B1 | 60 m | 443 nm | Ultra Blue (Coastal and Aerosol) |
| B2 | 10 m | 490 nm | Blue |
| B3 | 10 m | 560 nm | Green |
| B4 | 10 m | 665 nm | Red |
| B5 | 20 m | 705 nm | Visible and Near Infrared (VNIR) |
| B6 | 20 m | 740 nm | Visible and Near Infrared (VNIR) |
| B7 | 20 m | 783 nm | Visible and Near Infrared (VNIR) |
| B8 | 10 m | 842 nm | Visible and Near Infrared (VNIR) |
| B8a | 20 m | 865 nm | Visible and Near Infrared (VNIR) |
| B9 | 60 m | 940 nm | Short Wave Infrared (SWIR) |
| B10 | 60 m | 1375 nm | Short Wave Infrared (SWIR) |
| B11 | 20 m | 1610 nm | Short Wave Infrared (SWIR) |
| B12 | 20 m | 2190 nm | Short Wave Infrared (SWIR) |
Every single satellite revisits time is 10 days.
Because there are two satellites (Sentinel 2A and 2B), this means it has a combined constellation revisit of 5 days.
