Palau 2022-11 (Expedition) - Helen (Island) - Raw Images. In 100 Island Challenge Collection

In November of 2022, the 100 Island Challenge team visited Helen to collect large-area imagery as part of the Palau 2022-11 expedition. The imagery collected here resurveys of permanent sites established during the Palau 2017-06 expedition. For each site, a preview image and the raw digital images used to create composite large-area image products of the underwater sites have been made available. A general description of the methods used to acquire the images can be found in a README.txt file for each site. Site specific metadata can be found within a METADATA.txt file for each site.

2022年11月，百岛挑战（100 Island Challenge）团队参与帕劳2022-11号考察任务，赴海伦海域采集大视野影像数据。本次采集的影像数据用于复测帕劳2017-06号考察任务中设立的永久性水下科考站点。针对每个站点，均已开放获取预览图与用于制作该站点大视野合成影像产品的原始数码影像文件。影像采集方法的通用说明可在各站点对应的README.txt文件中查阅，各站点的专属元数据（metadata）则可在对应站点的METADATA.txt文件中获取。
