河流土地资源外业调查和界桩建立的技术探讨——以滹沱河山西段为例

Technical Discussion of Field Survey of River Land Resources and Boundary Pile Establishment—— Taking Shanxi Section of Hutuo River as an Example

本文以滹沱河山西段河流治导线外扩50 m范围内土地资源利用复核细化以及水利设施基础数据调查采集、河道管理范围界桩点设置与埋设工作为切入点,充分利用现有的影像和矢量数据等资料,结合在测区实地研究对象的共性与特殊变化情况,探讨在外业测量中安全、准确、高效的作业模式。

In this paper,the review and detail of land resources utilization in the area of 50 meters of the river governance line in Shanxi section of Hutuo River,the investigation and collection of water conservancy infrastructure data,the setting and burying of boundary piles in the river management area are taken as the breakthrough point.This paper deeply discusses the use of existing image and vector data,combined with the common and special changes of field research objects in the measured area.The safe,accurate and efficient operation mode in field survey is discussed.
