Hello! I build a displacement map for the Fogo volcano for 2017. I took a picture for January and build compared to this image for the following months. Here is an example of pairs of pictures on my models:
- 20170115_20170208
- 20170115_20170316
- 20170115_20170421
- 20170115_20170527
- 20170115_20170620
and so on.
Snap defines the master image for example 20170620, and not 20170115. When I build a blend map and take as master the image first 20170620, and then build another model where as the master image I take 20170115, the displacement map in each case turns out different.
In this case master 20170620
In the case master 20170115
Which image should I take as the master? The one that defines a snap using a function “InSAR Stack Overview” or is it always 20170115?
