摘要
利用GPS进行外业调绘验证,可以实现空间数据的快速定位,直观地判定地面物体特性等现势信息,实现土地利用信息的更新。实践证明,在土地利用动态监测中引入GNSS技术,可极大地提高土地利用现状外业调绘验证的效率、质量和时效性,大大节省人力和物力。结合GIS和RS,可以实现土地利用数据库的动态更新,及时掌握土地动态,为土地宏观调控提供决策依据,推动土地管理工作信息化和科学化。
With the support of 3S technologies,GNSS has made it possible to achieve the updated of land use information through the rapid positioning and determining the characteristics information of ground objects assisted by RS spatial data.Practice has proved that introduction of GNSS technology in the land use dynamic monitoring greatly improves the efficiency and quality of outside land use survey,and can save the manpower and other resources significantly.Combined GIS and RS,it is possible to realize fast and accurate land use dynamic update.
