Please take a look at this steps in this post,

Phase to elevation - BLACK product

I think this post is quite good start for you, also remember the criteria of SAR IMAGES before to go a head in the processing for example the perpendicular baseline is a key point of created the elevation map, Also, please have a look at this, [image] [image] Source I think it is very nice tutorial, but let’s do it easy, 1- Split, Select where is your AOI in which subswath IW1-IW2-IW3, 2- Apply orbit, 3- Back geocoding 4- Apply ESD 5- Create an Interfogram 6- Deburst 7- Goldenst…

However, in your case step 9 is as below,

And step 10 is phase to displacement instead of what is mentioned in here,

Concerning the reference point, I think it well discussed in this post,

Difference between vertical and LOS displacement

@ABraun can you please tell me why we have to add the reference point value and vertical displacemnt, in INSAR tutorial by Dr.-Ing. Diana Walter. Also, does the sign of the reference value is important or not??? [Screenshot_4]
