2015~2020年云冈石窟地表环境要素土地覆盖变化数据

数据集为2015~2020年云冈石窟地表环境要素土地覆盖变化数据，数据范围覆盖文保单位遗产区与缓冲区。数据为自行生产数据集，原始数据来源于高分辨率遥感影像WorldView系列，通过Google Earth下载得到真彩色合成产品，时间为2015年与2020年两期，利用面向对象与深度学习技术提取两期影像中的变化地物。该数据能够为不可移动文物孕灾环境受人类活动干扰影响情况提供数据支撑。

This dataset is land cover change data of surface environmental factors for the Yungang Grottoes spanning 2015 to 2020, covering the heritage zone and buffer zone of the cultural relics protection unit. It is a self-developed dataset, with raw data sourced from the WorldView series of high-resolution remote sensing images. True-color composite products for two time periods (2015 and 2020) were downloaded via Google Earth, and changed features in these two-phase images were extracted using object-oriented and deep learning technologies. This dataset can provide data support for evaluating the impact of human activities on the disaster-prone environment of immovable cultural relics.
