Figure 21.

InSAR velocity maps in line of sight from descending scenes with relative orbit number 144 of Central California and the San Joaquin Valley from Sentinel‐1 acquisitions and GNSS weekly displacements in the period 2015–2018.5. (a) InSAR velocity map without Global Positioning System (GPS) input and (b) with GPS input. (c and d) Velocity uncertainty maps corresponding to (a) and (b). The green circle in lower right corner of (a) depicts the position where the InSAR velocity is tied to the GPS velocity. Orange squares at center of images refer to GPS stations CRCN and LEMA (displacement time series shown in Figure 22).
