基于GPRS的数字测图模式研究

he Digital Mapping Mode Research Based on GPRS

文中提出基于GPRS的数字测图模式以实现远程数据通讯的思路。介绍了全站仪坐标数据到手机接收,测量草图的绘制与远程发送,主机对数据的接收,以及地形图绘制等完整的数字测图的流程。系统特点为:(1)实时成图,及时修改;(2)操作简单,符合测量者的测量习惯;(3)草图绘制依据遥感影像,不易出错;(4)提高工作效率,降低了外业人员的工作强度;(5)成本较低,用户几乎不需要另外投资设备。

In the paper,the author proposes a new mapping mode based on GPRS,and introduces the total procedure of digital mapping,such as how to transfer the coordinate data from total station to mobile phone,how to draw the surveying draft on mobile telephone and send it to host,and how to draw the topographic map.The system has the following characteristics:(1)Real-time mapping and modifying timely;(2)The operation is simple,according with the habit of surveyor;(3)Sketch rendering is on the bases of remote sensing image,which is not easy to go wrong;(4)Improve work efficiency, and reduce personnel working intensity;(5)Cost is low that users almost don't need additional equipment.
