Crustal Dynamics Data Information System

The Crustal Dynamics Data Information System (CDDIS) was initially developed to provide a central data bank for NASA's Crustal Dynamics Project (CDP). The Crustal Dynamics Data Information System (CDDIS) supports data archiving and distribution activities for the space geodesy and geodynamics community. The main objectives of the system are to store space geodesy and geodynamics related data products in a central data bank, to maintain information about the archival of these data, and to disseminate these data and information in a timely manner to NASA investigators and cooperating institutions.

地壳动力学数据信息系统（CDDIS）最初旨在为美国国家航空航天局的地壳动力学计划（CDP）提供一个中心数据仓库。地壳动力学数据信息系统（CDDIS）支持空间大地测量学和地球动力学领域的资料存档与分发活动。该系统的核心目标在于将空间大地测量学和地球动力学相关数据产品存储于中心数据仓库，维护这些资料的存档信息，并及时将这些数据和相关信息传播至美国国家航空航天局的调查员及合作机构。
