GoodyGIS卫星影像在1∶2000公路地形图测绘中的应用

Application of GoodyGIS Satellite Image in 1∶ 2 000 Highway Topographic Mapping

在公路建设项目的可研和初设阶段,测绘人员需要向设计人员快速提供地形图作为设计依据和参考。在公路1∶2 000地形图测量中往往需要对测区边缘进行少量地形图的修补测工作。文章从成本角度考虑,提出了运用GoodyGIS软件提供的免费遥感卫星影像来快速制作地形图的方法,并结合具体工程实例对成果精度进行比较分析,证实了GoodyGIS卫星影像数据在公路地形图测绘中的可行性和实用性。

In the research and preliminary stage of highway construction project,it is necessary for surveyors to quickly provide topographic maps to designers as the design basis and reference.In surveying of highway topographic map at the scale of 1∶2000,it is sometimes necessary to mend a few topographic maps in the edge of the survey area.Considering the cost,this paper proposes to use the free remote sensing images provided by GoodyGIS software to quickly obtain the topographic maps to meet the design requirements.The practicability of the satellite image data based on GoodyGIS in surveying and mapping of highway topographic map are confirmed by comparing and analyzing the data of a specific engineering example.
