摘　　要：针对大地测量数据标准在信息化大地测量生产、应用和服务过程中的重要性,本文详细研究了现代大地测量技术体系下的大地测量数据的内容、特点、分类原则以及分类方法,提出按照大地测量数据的专业特征、空间布局、数据时效、数据状态、数据类型、数据组织等特征从多个维度进行数据类别划分的方法,初步形成了大地测量数据内容框架标准体系,较好地满足了大地测量数据宏观逻辑组织和统一管理的数据标准要求。Because of the importance of the geodetic data standards during the informationized geodetic surveying production, application and service, this paper analyzed the contents, characteristics, classification principles and classification methods of geodetic data based on the modern geodetic surveying technology system, presented the data classification method that is from multiple dimension according to the characteristics including the professional features, spatial layout, data validity, data status, data types, data organization of geodetic data, and so on. Moreover, it initially formed the content framework and standard system of geodetic data, which would meet the data standard requirement on the macro logical organization and unified management of geodetic data.
