Hyperspectral data collections at University of Memphis 2025-07-23

This data was collected using a modified Resonon Pika L airborne system with custom airborne software. See the accompanying paper for details. The data is intended to be used uncompressed. Each archive contains one dataset comprising a number of cubes, the IMU data, and the packet data. Each will extract to its own folder. The cube data is encoded with vidpak. If the "download all" button was used, extract that .zip file into its component files first. On Linux, all dataset archives can be extracted at once into their respective folders with the command cat *.tar | tar ixv. After downloading of all files, and extraction of the dataset archives, the complete data can be verified using the command sha256sum -c ./manifest.sha256sum. The command will print warnings if files are missing, not extracted, or if checksums are incorrect.本数据集通过经过改装的Resonon Pika L机载系统搭配定制机载软件采集，详细说明请参阅配套学术论文。 本数据集建议以未压缩格式使用。每个归档文件包含一套完整数据集，内含若干数据立方体、惯性测量单元（Inertial Measurement Unit，IMU）数据与数据包数据，解压后将生成独立文件夹。其中数据立方体采用vidpak编码格式。 若使用"全部下载"按钮，请先将该.zip压缩包解压为其包含的组件文件。在Linux操作系统中，可通过命令`cat *.tar | tar ixv`一次性解压所有数据集归档文件至对应目录。完成全部文件下载与数据集归档解压后，可执行命令`sha256sum -c ./manifest.sha256sum`对完整数据集进行校验。若存在文件缺失、未正确解压或校验和不匹配的情况，该命令将输出相应警告信息。
