Thank you for this introduction. I am working with Sentinel 2 for aquatic environment related studies, especial submerged vegetation. I want to have more examples with how I could use to detect these vegetation and differentiate habitat of vegetation in coastal waters.
Professor, please answer, how do I display the image of Sentinel 1 in a format that I know what is under the surface of the earth, since it is a radar that can penetrate the earth
Thanks so much for this video!!! Please I am mapping marginal land in Europe using open source datasets like Sentinel-2 Global land cover(S2glc), Corine land cover, Pan-European High Resolution Layers (HRL) tree cover density, Natura 2000 network , DEM, European Soil Database Derived data etc... please do you have any suggestions on the type of reference dataset i can use for the accuracy assessment or any other suggestions please.
Hi there, I have 2 images of the same place/viewing conditions, 5 days apart. However, when i export them as GeoTIFF images and load them into Matlab for the purpose of doing change detection, they get loaded in with different sizes. i.e. one of the pictures is a 692x488x4 matrix while the other is a 692x550x4 matrix. I need them to be the same size. Is there a way I can shape them to be equal size without loosing data in SNAP? Would I use resampling for this also or something else? Thank you.
I think you are downloading one scene in Ascending while the other in descending mode. you have to download the images which have the same mode either ascending or descending. If you still have the problem try to clip (Mask) both of the images by using a shapefile that surrounds the area of interest.
As said at time 11.12 . I am not getting any automatically loaded profile and band are not assigned to RGB. so getting a Black image with white patches. What shall i do? I am doing it to prepare Landslide inventory. Can u suggest me something
You can consider SNAP as being a platform. While it provides basic general tools it is the host for other toolboxes. Those toolboxes provide thematic of sensor specific tools. The SMOS box provides functionality to read and investigate SMOS data.
Keep going mate! Great insights. From France.
Great Presentation.

Hi, I am also trying to detect submerged vegetation. Have you been successful in detecting the vegetation using this method?
Excellent video! Thank you!
Hi, great presentation. Really helpful. Thanks!
Nice Lecturing.Thank you very much
nice video I need one help how to mosaic snap using Landsat 8 and 5 data processing can u share the details or pls upload video
I used the satellites once through the Copernicus site, but this seems much easier. 😀

Thank you very much for this video , but can I used SNAP for analyzing pollution data from Sentinel 5 ?

すげーです。
Sir zip file can not be opened in snap new version
Great video but I cant clearly hear the audio :(
audio seems pretty clear to me
How about when yo get many images with clouds, is there a way to rectify a downloaded image using SNAP tool?

amazing and thanks alot

i had the same problem once. I downloaded another image file and it worked right away. try choosing another image from another date or place
You can assign the bands manually according to your requirement. For example B4, B3, B2 respectively for true color.
informative presentation
Amazing
Dear all, can someone clarify the difference between SMOS toolbox and SNAP?
You can consider SNAP as being a platform. While it provides basic general tools it is the host for other toolboxes. Those toolboxes provide thematic of sensor specific tools. The SMOS box provides functionality to read and investigate SMOS data.
sir need atmospheric correction tutorial using SNAP please help
You can use Sen2cor with SNAP for atmospheric correction. ESA has their lessons on how to use Sen2cor in youtube
Отлично рассказываешь. Жаль я не знаю английский
For applying correction to Sentinel 2 imagery see how to use Sen2cor plugin ua-cam.com/video/ZDjY1eJ-9kg/v-deo.html
