Hi…I need to perform coherence change detection to identify the landslides. What are the steps to perform coherence change detection? I’m not able to get any tutorial regarding that.
This topic refers to the same type of analysis: Changes between two correlation InSAR images
The example is for earthquakes, but the principle of identifying change is the same.
thank you for quick response
I’m not sure that the approach will work on vegetated areas. Moreover the landslides are phenomena slow developing in time unless you work on disaster event.
But this is the experience I have.
Yes I’m working on a disaster event and the area is a dense forest area. What approach do you suggest?
To detect landslides you usually search for a decrease of coherence between two images. This id however challenging when there is already no coherence before the landslide.
