The most effective method to Download Free Sentinel Satellite Data

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:

BandResolutionCentral WavelengthDescription
B160 m443 nmUltra Blue (Coastal and Aerosol)
B210 m490 nmBlue
B310 m560 nmGreen
B410 m665 nmRed
B520 m705 nmVisible and Near Infrared (VNIR)
B620 m740 nmVisible and Near Infrared (VNIR)
B720 m783 nmVisible and Near Infrared (VNIR)
B810 m842 nmVisible and Near Infrared (VNIR)
B8a20 m865 nmVisible and Near Infrared (VNIR)
B960 m940 nmShort Wave Infrared (SWIR)
B1060 m1375 nmShort Wave Infrared (SWIR)
B1120 m1610 nmShort Wave Infrared (SWIR)
B1220 m2190 nmShort 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.
