Hyperspectral data collection at University of Memphis 2024-02-23

This data was collected using a slightly modified Resonon Pika L airborne system. See the accompanying paper for details. The data is intended to be used uncompressed. Each archive contains one cube and will extract to the 2024-02-23-10-58-33_uniform/cube_NN folder. If the "download all" button was used, extract that .zip file into its component files first. On Linux, all cube archives can be extracted at once into 2024-02-23-10-58-33_uniform/ with the command cat *.tar.zst | zstd -d | tar ixv. After downloading and extraction (including the manifest and calibration), all extracted files can be verified using the command sha256sum -c ./manifest.sha256sum. The command will print warnings if files are missing or if checksums are incorrect.本数据集由经过小幅改装的Resonon Pika L机载系统采集所得，详细说明请参阅随附的研究论文。 本数据集建议以未压缩格式使用。每个压缩包均包含一个数据立方体（cube），解压后将生成文件至2024-02-23-10-58-33_uniform/cube_NN文件夹中。 若使用了“全部下载”按钮获取数据，请先将该.zip压缩包解压为其包含的独立组件文件。在Linux系统中，可通过命令cat *.tar.zst | zstd -d | tar ixv一次性将所有数据立方体压缩包解压至2024-02-23-10-58-33_uniform/目录下。完成下载与解压（包括清单文件与校准文件）后，可通过命令sha256sum -c ./manifest.sha256sum验证所有解压文件的完整性。若存在文件缺失或校验和错误，该命令将输出告警信息。
