GNSS控制网选点辅助程序的设计与实现

The Design and Implementation of Auxiliary Selection Point for GNSS Control Network

目前,测量平面控制网主要采用GNSS方式布设。但传统的GNSS控制网内业图上选点速度慢、复杂且容易出错,为此,笔者提出一种内业选点的"一笔构图法"。在构图完成之后,再利用程序进行控制点信息和边信息的统计输出检查,当满足技术设计要求之后,即可进行外业的踏勘埋石。实践表明,该法能够有效降低内业选点的复杂度,提高工作效率。

At present,the measurement plane control network is mainly used GNSS. However,the traditional GNSS control network on the industry map is slowly,complex and error-prone,therefore,the author put forward a kind of interior design point method called "Once Drawing for Building Graphics Method".After the drawing is completed,the program is used to statistical output the control point and side information and to check. When the technical design requirements are met,the excavation can be carried out.Practice shows this can effectively reduce the complexity of the internal selection point and improve the work efficiency.
