Space positioning technique

Through GPS pseudo-range smoothing experiment by carrier phase , the paper testifies if the precision of space positioning technique can satisfy the requirement of land use changing investigation .

通过GPS相位平滑伪距差分定位实验，研究验证该空间定位技术所能达到的精度能满足土地利用变更调查的技术要求。

With the rapid development of computer technique , communication technique , space positioning technique , remote sensing and visualization technique GIS hardware and software environment and the methods of spatial data acquisition , storage , access , analysis , representation and visualization will be improved continually and rapidly .

随着电子计算机技术、通讯技术、空间定位技术、遥感技术和可视化技术的发展，地理信息系统的硬、软件环境，数据采集、存贮、分析和表达等手段，势必要不断进步。
