Datasets description

  From May 25, 2008 to July 11, 2008, the ground feature spectrum was measured in the encrypted observation area of Linze station. Observation instrument: ASD spectrometer of Beijing Normal University, 350 ~ 2500 nm; Reference plate information: use 40% reference plate before June 15, and then change to 20% reference plate. The multi angle observation frame includes an old multi angle observation frame of Beijing Normal University, a new multi angle observation frame made by Beijing Normal University in 2008 and a new multi angle observation frame made by Remote Sensing Institute. Observation site: wulidun farmland quadrat, desert transition zone and Linze station quadrat.

  See the metadata "Heihe integrated remote sensing joint test: layout of quadrat transects in the densified observation area of Linze station" for the distribution and number of quadrat transects, and see the quadrat transect coordinates.xls of the densified observation station of Linze station for the quadrat location. Observation target: multi angle spectrum of surface features such as corn field and desert shrub. Data storage: data includes original data and preprocessed data.

  The original data is the binary file directly generated by the spectrometer, which can be opened with viewspecpro software. See the daily observation records in the data file for detailed observation records; The reflectance data obtained by preprocessing is in text format. Observation time: wulidun farmland sample (2008-05-25, 2008-05-28, 2008-05-30, 2008-06-29, 2008-07-11), desert transition zone (2008-05-28, 2008-05-30), Linze station sample (2008-06-25, 2008-06-30, 2008-07-09).
