HLS提供了每个像素的云、云影、雪、水和气溶胶光学厚度级别的遮罩。在HLS的早期版本中,云遮罩是由Level-1输入的云遮罩、大气校正代码LaSRC的内部云遮罩以及Fmask(Zhu等人2015年)的云遮罩的并集组成。在HLS v2.0中,云遮罩仅由Fmask 4.2生成,这是Qiu等人(2019年)报告的Fmask 4.0的更新版本。大气校正期间创建的气溶...
Compared to pan-sharpening and other upscaling methods, the proposed method can produce more realistic, spatial convincing images at 10 m resolution and more similar to Sentinel-2 images than the other commonly used super-resolution imaging algorithms. As a result, the proposed method extends the ...
Spatial resolution is 82 m in Landsats 1–3 and 30 m in Landsats 4, 5, and 7 (thermal band 60 m). b The thermal band is 120-m resolution on TM and 60-m resolution on ETM. c Panchromatic band 8 was added to ETM on Landsat 7. The TM was designed to improve the imaging ...
The Ball Aerospace & Technologies Corporation is building Landsat 9’sOperational Land Imager 2(OLI-2). OLI-2 will take measurements in the visible, near infrared, and shortwave infrared portions of the electromagnetic spectrum. The spatial resolution of its images will be 15 m (49 ft) for th...
The products are radiometrically harmonized as much as possible and resampled to a common 30-metre resolution, using the Sentinel-2 MGRS UTM grid. Spatial resolution: 30 metres. Revisit time: 2 – 3 days. Data availability: Since April 2013. Common usage: Vegetation monitoring, land use, land...

Major constraints on the RBV system spatial and radiometric resolution are the optical limitations of the camera lens, the sensitivity of the vidicon, the system noise and the video sampling rate. The Landsat-3 RBV lens resolution limit is 21.45 m ground equivalent half-cycle. The Earthnet video...
1. Spatial Resolution Thesize of an individual pixelin an image is called the spatial resolution. This pixel size determines the size of the smallest feature that can be distinguished in the image. Thesmaller the pixel size, the higher the spatial resolutionand the more detail the image contain...
318 tss data with spatial resolution of 30 m. the dataset is archived in .shp and .tif data formats, and consists of 341 data files with data size of 236 mb (compressed into one single file with 232 mb). the a...
