Cloud masking of Sentinel-2 product using SNAP

How do you process Sentinel 2 data in snap?

Preprocess a single dataset

1. Open File SNAP. Use SNAP’s toolbar to navigate to Raster > Geometric Operations and open the Resample operation:
2. Navigation to Resample.
3. Resampling settings tab 1.
4. Resampling settings tab 2.
5. Virtual product notification.
6. Open as RGB Image.
7. Subset function in Toolbar.
8. Subset function settings.

What is cloud masking in remote sensing?

Cloud masking in remote sensing prepares imagery for processing and improves product generation. In preprocessing cloud masking, cloud coverage is not the only trouble. Visibility is also reduced by the shadows they cast and thus decrease the reflectance capability of target objects.
 

How do I remove cloud cover from satellite images?

Detection of cloud in satellite imagery is done based on the pixel intensity (PI) value, and cloud removal is done by merging the spatial details of one subject image and two reference image having same location. This process is applied for whole subject image to obtain a cloud-free image.
 

What is a cloud mask?

Cloud Mask (Dense/Cirrus) The cloud mask enables cloudy and cloud-free pixels to be identified. The mask includes both dense clouds and cirrus clouds with an indicator specifying the cloud type. Processing is performed with data sampled at 60 m spatial resolution for all spectral bands.

How does the snap algorithm work?

The Snapchat algorithm works to show users the most engaging Snaps they’d be interested in. With the goal of serving the right snaps, to the right person, at the right time, it organizes the content you’ll see based on its importance and relevance to you一the key ingredients to a more personalized experience.
 

What is the method of recording snap?

Tap the Record icon (gray circle) to start recording your screen. Go to Snapchat and record the Story or Snap you want. Open Control Center again and tap the Record icon (red circle) again to stop recording. Your screen recording will be automatically saved in your Photos app.
 

What are the two methods for masking?

Common Methods of Data Masking

• Inplace Masking: Reading from a target and then updating it with masked data, overwriting any sensitive information.
• On the Fly Masking: Reading from a source (say production) and writing masked data into a target (usually non-production).

How do you use a cloud mask?

Apply the Cloud Mask to the Multispectral Source Image



From the menu bar, select File > Save As > Save As (ENVI, NITF, TIFF, DTED). In the File Selection dialog, select the multispectral dataset to which to apply the cloud mask.

What is masking and its types?

Masking is a technique or feature of this software through which you can merge two or more images in one image, cut any object from an image, remove the background of any image, and many more things you can do with this feature of Photoshop.

How do I get data from Sentinel-2?

All Sentinel-2 data are freely available from the Copernicus Open Access Hub. Users can download the data via https://scihub.copernicus.eu/.
