全站仪和GNSS-RTK联合在数字测图中的应用

目前,地面数字测图一般都采用全站仪、GNSS-RTK或者两者结合。全站仪测图具有精度高、使用方便等优点,而GNSS-RTK具有精度高、工作距离长和不存在误差累计等优势,为克服各自的不足,提出了数据采集中综合应用GNSS-RTK和全站仪的方法,开发设计了全站仪和GNSS-RTK集成的数字测图系统,利用实测数据对其进行验证。针对集成中可能出现的问题给出解决办法和措施,得出有益的结论,可以借鉴到类似的工程中。

Application of Total Station and GNSS-RTK in Digital Mapping

At present, we use total station, GNSS-RTK or both in the surface digital mapping.The total station has the advantages of high accuracy, easy to use, and GNSS-RTK has advantages such as high accuracy, long working distance and no accumulated er-ror.In order to overcome their shortcomings, we proposed the method of integrated application GNSS-RTK and total station in data acquisition.In view of the problems that may arise in the integration, we give some solutions and measures, and draw useful conclu-sions, which can be used for reference to similar projects.
