林业大型线状工程外业调查技术探析

Field investigation techniques of large-scale linear forestry projects

该文主要基于林业大型线状工程的外业调查技术进行研究,通过对传统林业外业调查技术、无人机外业调查技术和遥感+Dailyroad外业调查技术3项技术对比分析,得出如下结论:传统外业调查技术人工成本高,耗费时间长,外业调查成果不方便进行复查核对,不适合林业大型线状工程使用;无人机外业调查技术成本高;遥感+Dailyroad外业调查技术耗费时间较短,人工成本较低,技术成本低,外业调查数据能够进行及时核对复查,同时该项技术可操作性强,对专业技能要求低,将为林业调查带来极大方便,推动林地调查技术的不断革新。

This research is mainly based on the field of large-scale forestry engineering survey technology.Through the comparative analysis of the traditional forestry field survey technology,UAV field investigation technology and remote sensing ＋ Dailyroad field survey technology,three conclusions are drawn as follows：It is not suitable for forestry large-scale linear project.The field survey technology of UAV has high technical cost and high cost.Remote sensing ＋ remote sensing ＋ Daily field survey technology can reduce the cost of labor,the cost of labor is low,the field survey data can be checked and checked in time,and the technology can be operated easily,with low requirement for professional skills,strong maneuverability,will bring great convenience for forestry investigation,and promote the continuous innovation of forest land survey technology.
