嵌入式数字测图系统开发中展点功能的实现

The Realization of Drawing Points in Embedded Digital Mapping System Development

嵌入式数字测图系统开发指的是:在智能测量设备上,即具有操作系统的GPS或全站仪等,直接开发数字测图系统;而在数字测图系统中,必须实现程序的展点功能,即根据测量的坐标文件,实现在屏幕上画点的功能,然后才能对点连接,形成各种地物地貌。

Embedded digital mapping systm development imply thai on th intelligentmeasurement equipment the has the operating system such as GPS or total station, digital mapping systems are developped directly ： while in the digilal mapping system, we roust implement the program of the drawing points, and based on the measurement of the eoonlinate file , the timetions in the point of the painting on the sereen are achieved, and lilen varietv of surface features landforms ean be drawed.
