3.5d-DEM optimization-Zagros Ranges [shifted & smaller region]
Multi-dimensional DEM [ALOS(median, average), SRTM, ASTER] at 1 arc sec spatial resolution, SE Zagros Ranges (the study area of data3 is greater than the study area of data1, 1920*1920 pixels versus 1601*1601 pixels - study area1 = 0.7 of study area3, while it is shifted a bit to west and so it is not contains in study area 4 (to present the sifting in local maxima of ALOS versus SRTM centroids in between study areas 4 and 3).
