High Mountain Asia glacier velocities 2013-2015 (Landsat 8)

This dataset contains the median glacier surface velocity for the Pamir-Karakoram-Himalaya for the years 2013-2015 (Landsat 8 only). The velocities has been obtained by feature-tracking of Landsat images spaced 1 year apart. The folder contains the following fields at 120 m resolution in GeoTiff format: - the velocity magnitude 'vel' (meters per year) - the x/y velocity components x_vel/y_vel (meters per year) - the associated errors err, x_err, y_err (meters per year) - the standard deviation of all the merged velocities 'std' (meters per year) - the number of image pairs that have been merged in the median I recommend filtering data with error larger than 10 m/yr. For more information and any use of the data, please refer to Dehecq, A., Gourmelen, N., Trouve, E., 2015.

Remote Sensing of Environment 162, 55–66. https://doi.org/10.1016/j.rse.2015.01.031本数据集包含2013-2015年帕米尔-喀喇昆仑-喜马拉雅山脉的冰川表面中位速度（仅使用Landsat 8数据）。该速度数据通过对间隔1年的Landsat影像进行特征追踪获取。 该数据集文件夹包含以下120米分辨率的GeoTIFF格式数据字段： - 速度幅值`vel`（单位：米/年） - 速度的x、y分量`x_vel`、`y_vel`（单位：米/年） - 相关误差项`err`、`x_err`、`y_err`（单位：米/年） - 所有合并速度的标准差`std`（单位：米/年） - 中位速度计算中所合并的影像对总数 建议对误差大于10米/年的数据进行过滤。 如需获取更多信息或使用本数据，请参考以下文献：Dehecq, A., Gourmelen, N., Trouve, E., 2015. 从完整卫星档案提取大规模冰川速度：以帕米尔-喀喇昆仑-喜马拉雅山脉为例. 环境遥感（Remote Sensing of Environment）, 162卷, 第55-66页. https://doi.org/10.1016/j.rse.2015.01.031
