Society Islands 2021-05 (Expedition) - Raiatea (Island) - Raw Images. In 100 Island Challenge Collection

In May of 2021, the 100 Island Challenge team visited Raiatea to collect large area imagery as part of the Society Islands 2021-05 expedition. The imagery collected here established permanent sites that can later be resurveyed as part of the 100 Island Challenge Project. 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.

2021年5月，百岛挑战（100 Island Challenge）团队前往赖阿特阿岛（Raiatea）采集水下大面积影像数据，作为2021-05社会群岛科考远征任务的一部分。此次采集的影像划定了永久性监测点位，后续可作为百岛挑战项目的组成部分开展复勘工作。针对每个监测点位，用于生成水下点位大区域合成影像产品的预览图与原始数码影像均已对外公开。关于影像采集方法的通用说明可查阅各点位附带的README.txt文件；点位专属元数据则可在各点位的METADATA.txt文件中获取。
