The deposition and post-eruptive elevation change rate map of the 2008 Okmok eruption

Here are the results in a paper entitled "Characterization of the 2008 phreatomagmatic eruption of Okmok from ArcticDEM and InSAR: deposition, erosion, and deformation" submitted to JGR Solid Earth in 2019. It includes the 2-m resolution surface elevation change of the 2008 Okmok eruption (Fig. 2a in the paper) and the 2-m resolution post-eruptive elevation change rate map (Fig. 3), as well as the corresponding uncertainties (Fig. S3). It also includes the boundary of the proximal deposit field classified using a minimum elevation increase of 2 m, the boundary of large slope failure, and the shorelines of two lakes (Figs. 2a, S5, and S6) at different acquisition times. The GeoTIFF files can be viewed in free and open-source software QGIS, in Google Earth, or by Matlab using code https://github.com/ihowat/setsm_postprocessing/blob/master/readGeotiff.m. The shapefiles can be viewed in QGIS and Google Earth.

本数据集包含2019年提交至《JGR Solid Earth》的题为《基于北极数字高程模型（ArcticDEM）与干涉合成孔径雷达（InSAR）的奥克莫克2008年射汽岩浆喷发（phreatomagmatic eruption）特征：沉积、侵蚀与形变》的研究论文中的相关成果。数据集包含2008年奥克莫克喷发的2米分辨率地表高程变化数据（对应论文中图2a）、喷发后2米分辨率高程变化速率分布图（对应论文中图3），以及对应的不确定性数据（对应论文中图S3）。此外，数据集还涵盖以最小高程增幅2米划分的近源沉积区边界、大型边坡失稳区域边界，以及不同采集时刻下两个湖泊的湖岸线（对应论文中图2a、S5与S6）。地理标记图像文件格式（GeoTIFF）文件可通过免费开源软件QGIS、谷歌地球（Google Earth）查看，也可使用MATLAB结合代码https://github.com/ihowat/setsm_postprocessing/blob/master/readGeotiff.m进行读取与查看。形状文件（Shapefile）格式的矢量数据可通过QGIS与谷歌地球查看。
