Data for: Understanding Volcanic Geomorphology from Derivatives and Wavelet Analysis: case study at Miyakejima Volcano, Izu Islands, Japan

For the island of Miyakejima, the dataset includes a contour-line GIS data of the topography, the DEMs produced and the DEMs derivatives (slope, hillshade, wavelet decomposition and residual mapping).
The dataset is either projected in WGS84 or not projected (no projection file was created during the Matlab processing).

针对三宅岛（Miyakejima），本数据集包含地形等高线地理信息系统（Geographic Information System，GIS）数据、生成的数字高程模型（Digital Elevation Model，DEM）集，以及数字高程模型衍生产品（坡度、山体阴影、小波分解与残差映射）。该数据集可采用WGS84（World Geodetic System 1984）坐标系投影，亦可不进行投影（Matlab处理过程中未生成投影文件）。
