摘要
本文讨论使用差分GPS进行道路测量数据采集中遇到的几个重要问题。外业数据采集主要解决了GPS道路观测数据、地物属性数据以及匹配时间数据的获取的问题 ;内业数据处理解决了如何用差分GPS方法获得满足要求的道路矢量数据 ;地物属性匹配解决了矢量数据和属性数据之间的融合 。
Several key problems are discussed in the paper,which occur in the data collection of the vehicle carried DGPS highway surveying.The pooblems than how to obtain the data by field data collection,which includes GPS highway surveying data and attribute data of terrestrial objects and also the data of time-matching between them ae resolved.The problem of obtaining highway vector-data with DGPS by data processing in the office is also resolved.The integration of vector-data and attribute-data can be resolved by the attribute matching of terrestrial objects,which are the basic Data of Geo-scientific infrastructure.
