边碎部边控制的数字化测图及坐标转换程序设计

Digital Mapping and Coordinate Transformation Arithmetic Design

介绍一种边碎部边控制的数字化测图方法,讨论其基本原理,设计了坐标转换算法和坐标转换程序,提出在数字化测图实践中的意义.实践证明,采用该方法控制点选点结束后可同时进行控制测量和碎部测量,不仅可改善作业组织和分工形式,有利于充分利用各类仪器设备和人力资源;而且还可以加快作业速度,提高工作效率.

A new way of digital mapping is introduced, and its basic principle and application in digital mapping are discussed. The arithmetic and the procedure of coordinates transformation is also provided in C ＋ ＋ It is certified in surveying and mapping practice that the new way of digital mapping is efficient both in homework and field work.
