Difference between vertical and LOS displacement Microwave Toolbox

Hello everyone, I am trying to estimate building subsidence for the area of Ho Chi Minh in Vietnam. I have used 6 interferograms (between June 2016 and June 2017) where I stacked them and produced the subsidence map. Firstly, I produced displacement in LOS geometry using the following equation. unwrapped (phase * wavelength) / (-4 * PI) (or ‘phase to displacement’ from SNAP where the results are the same). I also calculated the vertical displacement using the following equation: (unwrapped ph…
