1986-2022年Landsat系列卫星亚非沙漠蝗虫灾情监测NDVI产品

1986-2022年Landsat系列卫星亚非沙漠蝗虫灾情监测NDVI产品主要包括1986年-2022年基于Landsat5/7/8所得遥感影像反演而得到的ndvi图像共107662景。Landsat-8是美国陆地卫星计划（Landsat）的第八颗卫星，由NASA与美国地质调查局（USGS）合作开发并于2013年2月11号发射成功。Landsat8 卫星包含OLI（Operational Land Imager 陆地成像仪）和TIRS（Thermal Infrared Sensor 热红外传感器）两种传感器。OLI陆地成像仪包括9个波段，空间分辨率为30米，其中包括一个15米的全色波段，成像宽幅为185kmx185km。TIRS热红外传感器TIRS包括2个单独的热红外波段，空间分辨率为100米。（协议共享）

The NDVI products for monitoring desert locust disaster conditions in Asia and Africa using Landsat-series satellite data from 1986 to 2022 mainly include a total of 107,662 NDVI image scenes retrieved from remote sensing images acquired by Landsat 5, 7, and 8 during the period 1986 to 2022. Landsat-8 is the eighth satellite of the U.S. Landsat Program, jointly developed by NASA and the United States Geological Survey (USGS), and successfully launched on February 11, 2013. The Landsat 8 satellite is equipped with two sensors: the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS). The OLI consists of 9 spectral bands, with a spatial resolution of 30 meters, including a 15-meter panchromatic band, and an imaging swath of 185 km × 185 km. The TIRS includes two separate thermal infrared bands, with a spatial resolution of 100 meters. (Data shared under agreement)
