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).

空间分辨率为1角秒的多维数字高程模型（Digital Elevation Model, DEM）数据集，覆盖扎格罗斯山脉东南部区域，包含ALOS（中值、平均值）、SRTM、ASTER三类数据源。其中，数据集3的研究区域面积大于数据集1，二者像素尺寸分别为1920×1920与1601×1601——数据集1的研究区域面积为数据集3的0.7倍，且其位置略微西移，因此未被包含在研究区域4内；该数据集的区域设置旨在呈现研究区域4与3之间ALOS与SRTM质心的局部极大值偏移情况。
