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 Miyakejima 岛，该数据集涵盖了地形等高线 GIS 数据、生成之数字高程模型（DEM）及其衍生物（包括坡度、阴影、小波分解和残差映射）。数据集投影系统为 WGS84 或未进行投影（在 Matlab 处理过程中未创建投影文件）。
