            "ds_source": "<p>&emsp;The data were acquired by the HY-9010-L UAV-borne hyperspectral imaging system. The system uses a CMOS detector with an angular spatial resolution of 0.7 mrad at F=35 mm. It provides 1920 (1×), 960 (2×) and 480 (4×) spatial channels; in this dataset, the 480-channel mode is used. The spectral channels are 1200 (1×), 600 (2×) and 300 (4×); here, the 300-band mode is adopted. Data are recorded through a USB3.0 interface with a maximum frame rate of 128 fps. The original images are stored in ENVI Standard format, with image sizes of 6560×480 and 41701×480 (lines×samples), 300 spectral bands, 64-bit floating-point data type (data type = 12) and BIL interleave. The ENVI header files record the central wavelength of each band (unit: nm).",
            "ds_quality": "<p>&emsp;Before acquisition, the system was spectrally and spatially calibrated. During the flights, radiometric calibration was performed using standard white reference panels and dark current measurements, which removed most striping and dark-current noise. Flight segments that suffered from severe over-exposure, motion blur, or cloud-shadow contamination were discarded. Within the spectral range, the data exhibit high signal-to-noise ratio and good spectral continuity; a few bands at the spectrum edges may be affected by sensor response decay and can be removed if necessary. Overall, the data show small geometric distortion and smooth spectral curves, and they meet the requirements for detailed spectral analysis and classification.",

The sensor covers a spectral range of approximately 400–1000 nm with a spectral resolution better than 2.8 nm. Using the 4× spectral/spatial binning mode, 300 spectral bands and 480 across-track spatial channels are obtained. The original ENVI data cubes have spatial sizes of about 480×6560 pixels and 480×41701 pixels (two flight strips), with 300 bands spanning approximately 388–1025 nm. The dataset can be used for detailed land-cover classification, riverbank material composition analysis, and surface environmental monitoring.\r\n<p>&emsp;The data are stored in ENVI Standard format and can be directly opened in ENVI / ENVI Classic via “File → Open Image File” by loading the .hdr files, or read via GDAL in software platforms such as QGIS and ArcGIS.",
