This video is a complete tutorial in which you learn basic and applicable topics in the SNAP software which is one of the powerful software in processing especially working with sentinel images. we've started in the very beginning stage that includes Downloading and installing SNAP software, then concentrated on applicable topics such as downloading Sentinel images, Subset, drawing Histogram, processing sentinel-1 images, collecting training samples, Classification, PCA, GLCM and so on. Moreover, the download links ,which we've used in the video, have been provided for you to access the website easily. if you have any questions, feel free to ask in the comment section.

@rsgis6997 2 жыл бұрын

Hello To identify different classes in Sentinel 1 images, which are radar images, it is necessary to know the backscatter of the phenomena Usually, built-up urban areas have more brightness in the image, and water is at its blackest

Hello, and thank you for the presentation. I have three questions: 1) Does SNAP 9.0 have a Fourier Transform option from a SLC-SAR image? 2) I am interested to learn more about the custom filter design process. For example, can you make a truncated bandwidth filter set from two partially overlapping sectors of the azimuth along-track domain to detect micro Doppler signals? 3) You showed how you can perform histogram analysis of lines. Does that mean that you can focus the processing on a series of pixels on a straight line sample of your choosing from the SAR image?

For a research project at my university we have to build an active corner reflector for sentinel-1a. Therefore I need to know the „grey values“ (in dBsm) of the image/region I am interested in. How can I read out such a scale? Thank you very much!

@rsgis6997 Жыл бұрын

Hello By using this training, you can do the desired pre-processing and finally reach intensity Is the intensity band you need?

@user-np8vl3cx1p Жыл бұрын

Actually: I don’t really know. The main work of the project shall be to build the reflector which is going pretty well. I’ve got the task to research about sentinel-1a and find out about the required RCS. There are a few papers referring to the same (not more existing) source that the required RCS in dBsm shall be 40.4. I was told to validate this value with the offered data and the snap tool. Now one of our problems is, that we are in the early semesters and haven’t had lessons in radar. So, yeah In the last month I have read much about how a (sar) radar works. I thought that asking someone with knowledge could be the better way, so I ask you. Do you understand what I mean? If not it’s okay, I will not stop reading and thank very very much for your video it was indeed easy to follow and thank you very much for your time :)

@@user-np8vl3cx1p Actually, I didn't fully understand what you meant But you can use the software to extract any phenomenon The range of gray values is different for phenomena You can roughly extract any phenomenon by using a gray values interval image Or you can search in the articles for its exact extraction

Thankyou Sir. Can you please explain how to geocode a sentinel image on SNAP?

@rsgis6997 2 жыл бұрын

Hi mate, glad you enjoyed the video, to geocode you can use the video, at first your images should be pre-processed such as S 1 TOPS Split and Apply Orbit File. Then, follow this address: Radar Tab >> Coregistration section >> S 1 Coregistration >> Back geocoding. Click on Back geocoding and enter your images, you also need to set the DEM on SRTM 1sec HGT and then RUN to processing be performed.
