Run processes of SNAP toolbox using python script

[sohelmsc]

Hi,

I am new user of SNAP toolbox. I have installed SNAP 4.0 in my windows machine. I am currently using SNAP desktop and it is working perfect. However, I am wondering whether it is possible to run defferent processes like coregistration, coherence estimation etc. squentially using a python script. It would be great if you could provide an example script.

Thanks in advance.

Snappy: Where to start?

Good afternoon, I am a new ESA Trainee and I would like to implement some of the processes of S2-tbx/sen2cor into a online platform. As a programming language I am going to use python. Are there beginner guides, handbooks or well documented scripts available? Until now I found: How to use the SNAP API from Python: https://senbox.atlassian.net/wiki/display/SNAP/How+to+use+the+SNAP+API+from+Python -> I could install snappy properly and run “snappy first contact” Scripts https://github.c…

Snappy function for radiometric calibration and terrain correction

Hi there, I’m trying to use SNAP with Python. I tried the snappy examples and everything worked fine. But I would want to perform radiometric calibration (i.e., calculating sigma0) and terrain correction with a Sentinel-1 product. Where can I find the functions for that? I already looked into http://step.esa.int/docs/v2.0/apidoc/engine/ and found the “Orthorectifier” function, if that’s the right one. But I can’t find anything about “Calibration”. Is there some kind of user-guide or handbook f…

Python codes of GLCM for texture feature extraction

Any idea how to have access to Gray Level Co-occurence matrix (GLCM) python codes for SAR texture feature extraction? I would like to run the texture analysis on SAR Terrain correction data in order to produce “entropy”, but through the python. Your help is very appreciated.

Cheers,
Andreas

About the python category

Put your question regarding the usage of snappy, the snap-python interface or anything else related to Python and SNAP into this category. This could be questions regarding the access of the SNAP API from Python or implementing an operator in Python, all questions like this are best suited here. Question regarding Sen2Cor should go into the sen2cor category. General documentation about snappy can be found in How to use the SNAP API from Python of the Developer Guide. There is also a page which…

@abgbaumann
Hie,
Can you please give me the exact code to do SNAP operation using python. It would be a great help to me.
Thanks

[ABraun]

please don’t repeat the same question within the same topic. One time is enough.
You find many example codes here:

senbox-org/snap-engine

No, we can’t give the exact because each processing is different. Andreas pointed you already to some examples, helpful is also the following guide:
https://senbox.atlassian.net/wiki/spaces/SNAP/pages/24051781/Using+SNAP+in+your+programs

And there should something remain what you are doing. We can’t do all the work for you.
Sorry.
