MULTIPLE-POINT GEOSTATISTICS TO DERIVE MISSING SURFACE DISPLACEMENT VALUES OF A GLACIER INFERRED FROM DINSAR

B. Ranjit, V. A. Tolpekin, A. Stein
2019 ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences  
The glacier displacement map produced by DInSAR contains missing values due to decorrelation of the SAR images.  ...  This study demonstrates the utility of direct sampling—a well-established multiple-point geostatistics method—for deriving those missing values.  ...  Whereas, geostatistical methods are based on statistical models performing stochastic predictions of values at unknown locations, and therefore can provide spatial model of uncertainty.  ...
