中亚地区植被覆盖度时空变化数据(2010、2015、2020)
收藏资源简介:
本数据集包括2010、2015和2020年间,中亚地区五国(哈萨克斯坦、吉尔吉斯斯坦、塔吉克斯坦、土库曼斯坦和乌兹别克斯坦)的植被覆盖度(FVC)数据。该数据由MODIS-NDVI数据集(产品编号MOD13A2.006),根据干旱区植被盖度与NDVI之间的经验关系计算得到。该产品时间分辨率为1年,空间分辨率1 km。算法从当年所有观测数据中,以低云、低探测角度和最高NDVI值为标准,选择最佳的可用像元值,并进行换算。
This dataset provides Fractional Vegetation Cover (FVC) data for the five Central Asian countries—Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan—covering the years 2010, 2015, and 2020. The FVC data was derived from the MODIS-NDVI dataset (product ID: "MOD13A2.006") using an empirical relationship between vegetation cover and NDVI in arid regions. The MODIS-NDVI product has a temporal resolution of 1 year and a spatial resolution of 1 km. The adopted algorithm selects the optimal available pixel values from all annual observational data following the criteria of low cloud cover, low detection angle, and the highest NDVI value, and performs the required conversion calculations.
