Datasets description

This data set was acquired by the airborne widas sensor on July 7, 2008, in the ARJO flight area.

The imaging frequency of the visible near-infrared band of the original data is low, which is seriously affected by clouds and cloud shadows, and it is difficult to carry out automatic geometric correction because of the lack of feature points on the ground. Therefore, level-2b data products and mosaic images that have been partially radiometrically corrected and manually geometrically corrected are released to ordinary users. The resolution of visible near-infrared band is 1.25m, and the saved physical quantity is radiance, with the unit of W / (SR · m ^ 2 · nm). The conversion formula is DN = radiance × 100000, the physical quantity stored in the thermal infrared (TIR) band is the bright temperature of the sensor entrance pupil, the unit is: ℃, and the conversion formula is DN = brightness_ Temperature × 100。

The data processing time is February 2010. The original data (level-1a data) can be archived only after the application is submitted and approved.

Data source description

This data set was acquired by the airborne widas sensor on July 7, 2008, in the ARJO flight area. The data processing time is February 2010. The original data (level-1a data) is archived and can only be obtained after submitting an application and approval. The original data of this data set includes 4 routes.

Data processing method

For level-2b data products and mosaic images after radiometric correction and manual geometric correction, the resolution of visible near-infrared band is 1.25m, and the stored physical quantity is radiance, with the unit of W / (SR · m ^ 2 · nm). The conversion formula is DN = radiance × 100000, the physical quantity stored in the thermal infrared (TIR) band is the bright temperature of the sensor entrance pupil, the unit is: ℃, and the conversion formula is DN = brightness_ Temperature × 100。
