Extract Urban Built Up Area Footprint from SAR Data Using ESA SNAP. Part 2 Coherence Analysis

How to extract Built Up Area or Urban Footprint from SAR Data ( Sentinel 1 SAR ) using ESA SNAP. This is the second part of the SAR Analysis for urban mapping that I made for this channel. This time I will exploit SAR coherence to map the built up area

Hello GEO2004, Thank you for making this tutorial. Can you please make a video on using ISCE for subsidence mapping using InSAR?

Can you please tell that how to do the decomposition of Sentinel data on SNAP?

In your opinion which one gives better results? This or Pt 1. Speckle Divergence Method

Hey!
Besides Coherence Analysis and Speckle Divergence, are there any other methods to extract urban built up areas or urban footprints from SAR images/data? Thank you :)

How can open urban foot print band in arc map.

Hello. first of all thank you for this video, its really helpfull.
But i got problem.
I followed your instructions easily and manage to create coherance change map but problem was 2 images was overlapping. So i check the datas and realize center of the images are like 200 meters away from eachother. So it affected all the result.
I did some search and see that i can use coregistration to solve this issue but when i did coregistration it automaticly doing orbit, slicing, backgeocoding etc and as a output it gives me only 1 file. Which i need 2 to do your training. So i tried to split them by creating 2 of them and deleting one image from one folder and other image from second folder but in the end i encountred other problems.
Can you give me some advices please ? I have a deadline and i need to finish this somehow.
Thank you in advance!

thank you, , is it a requirement that the two images must have the same orbit to be coherent?

Nice! Keep it up! Would you like to be YouTube friends? :)
