Application of Landsat-8 OLI/TIRS and digital elevation model dataset in spatial modelling of land surface temperature

Landsat-8 OLI/TIRS satellite image of 14th March 2020, Path 185/Row 054 at UTM Zone 33, captured at 09:25 am local time by two sensors. OLI bands include: Bands 1 (Coastal aerosol), 3 (Green), 4 (Red), 5 (Near Infrared), 6 (Shortwave Infrared 1), 7 (Shortwave Infrared 2). TIRS band was – Band 10 (Thermal Infrared Sensor). These are radiometrically- and geometrically-corrected data products, including the application of ground control points and digital terrain model corrections. The OLI bands are sampled at 30m spatial resolution while the thermal band captures the land surface as 100m but provided as 30m resampled product by United States Geological Survey (USGS) so as to conform to the OLI bands. The SRTM DEM dataset was processed from raw C-band radar signals spaced at 1 arc-second intervals (30m).

2020年3月14日Landsat-8 OLI/TIRS卫星影像，位于UTM区域33的185路径、054行，当地时间上午9:25由两个传感器捕获。OLI波段包括：波段1（沿海气溶胶）、3（绿色）、4（红色）、5（近红外）、6（短波红外1）、7（短波红外2）。TIRS波段为波段10（热红外传感器）。这些数据产品经过辐射校正和几何校正，并应用了地面控制点和数字地形模型校正。OLI波段以30米空间分辨率进行采样，而热波段以100米分辨率捕捉地表，但由美国地质调查局（USGS）提供30米重采样的产品，以确保与OLI波段的一致性。SRTM数字高程模型数据集由原始C波段雷达信号处理而成，信号间隔为1弧秒（30米）。
