摘要
探讨了利用GPS整合星基增强系统(SBAS)卫星信号进行绿化调查的过程,并通过应用实验验证该技术的定位精度。在此基础上,基于掌上电脑(PDA)集成移动GIS和GPS,实现了GPS WGS-84坐标转换为城市平面坐标,进行了校园绿化调查,取得了较好的定位精度。
This paper presents a method of integrating GPS and the signal of SBAS for landscape survey on campus.A test is carried out to verify the positioning accuracy of the technique.Based on this,the system integration of mobile GIS and GPS is developed based on the personal digital assistant（PDA）,achieving the transformation from the WGS-84 coordinates to the city planar coordinates,surveying the landscape on the campus,and obtaining the required positioning accuracy.
