全球Landsat8优质影像数据集

2013 年2月11日，美国航空航天局(NASA) 成功发射Landsat-8卫星。Landsat-8卫星上携带两个传感器，分别是OLI陆地成像仪（Operational Land Imager）和TIRS热红外传感器（Thermal Infrared Sensor）。
Landsat-8 在空间分辨率和光谱特性等方面与Landsat 1-7保持了基本一致，卫星一共有11个波段，波段1-7，9-11的空间分辨率为30米，波段8为15米分辨率的全色波段，卫星每16 天可以实现一次全球覆盖。

On February 11, 2013, the National Aeronautics and Space Administration (NASA) successfully launched the Landsat-8 satellite. The Landsat-8 satellite carries two sensors, namely the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS).
Landsat-8 maintains basic consistency with Landsat 1-7 in terms of spatial resolution and spectral characteristics. The satellite has a total of 11 spectral bands: the spatial resolution of Bands 1–7 and 9–11 is 30 meters, while Band 8 is a 15-meter-resolution panchromatic band. The satellite can achieve global coverage once every 16 days.
