Application of Cutting-edge Technologies in Yellow Rivers Basic Surveying and Mapping
Basic surveying and mapping for the Yellow River is the preliminary work of Yellow River s integrated management and development.And its technical content is rising as the related disciplines scientific and technological progress.Applying cutting-edge mapping technologies in the Yellow River s survey can show the survey s quick response ability for integrated management and development of the Yellow River basin.When surveying the 1:10,000 topographic map in Xia0beiganliu of Yellow River,we integrate many new mapping technologies together,such as ADS80 digital aerial photography,ALS60 Airborne LiDAR,GPS PPP and region geoid s refinement.Compared to the traditional aerial survey,these new mapping technologies have changed the work mode of many operations,including the selection and measurement of aerophoto control point,aero-photo scanning,aerial triangulation,and survey for elevation annotation points in flood land.And they not only greatly improve the quality and operating efficiency of mapping products,but also reduce the field labor intensity.This paper elaborates the project s work process,main methods,key technologies and mapping accuracy,which will be of instructive and promotional value for the implementation of similar projects.
