本文选取青藏高原一座雪山作为研究试点,采用SPOT5卫星的HRS数据特有的立体像对采集功能,生成DEM,建立青藏高原冰雪三维监测模型,基于TIN计算雪被表面积,并结合以往研究成果估算冰雪规模,达到用尽量少的数据源对冰雪区开展调查,最大限度节省人力物力的目标。为有效管理我国冰雪资源、国家宏观水资源调控和可持续发展提供科学参考。
In this paper, we selected a snow mountain in the Qinghai-Tibet Plateau as a research pilot. We use the stereo image acquisition function unique to the HRS data of SPOT5 satellite to generate DEM and establish a three-dimensional ice and snow monitoring model for the Qinghai-Tibet Plateau. The snow surface area is calculated based on TIN. , To achieve as little as possible data sources to carry out the investigation of the ice and snow area, to maximize the goal of saving manpower and resources. It provides a scientific reference for the effective management of China’s ice and snow resources, the state’s macro-control and sustainable development of macroscopic water resources.
