Paleo Islands and Archipelago Configuration (PIAC) database

The Paleo Islands and Archipelago Configuration (PIAC) database containins sea level driven paleogeography changes over the late Quaternary of 178 islands in 27 archipelagos. The workflow developed to calculate archipelago configuration and paleo-area is provided to allow calculations for other islands, time steps, and higher spatiotemporal resolutions.古岛屿与群岛配置（Paleo Islands and Archipelago Configuration, PIAC）数据库收录了27个群岛内178个岛屿在晚第四纪时期受海平面变化驱动的古地理演化数据。本数据集配套提供了用于计算群岛配置与古面积的工作流程，可支持针对其他岛屿、不同时间步长以及更高时空分辨率的相关计算任务。
