Results of the Application of the Topography Mask to the Resampled GTOPO'30 DEM for 2 ERS Frames
The ERS frames covering Irbeiskii (32543_2475_GTC) and
Ulkanskii (32657_2493_GEC) are analysed.

= mean)
1.2 Comparison of Threshold Level
Comparison of threshold level {1.01, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8} (window size = 20, filter
= median)
Comparison of threshold level {1.01, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8} (window size = 20, filter

1.3 Comparison of Masking Filter Types (not the same filter as applied to the DEM)
Comparison of filter type {median, mean} (window size = 20, threshold = 1.01)
