Speed and accuracy were requirements of engineering geological investigation and design for emergency control of landslides

but it was difficult to achieve because the detail site work was usually restricted by field environmental conditions of landslides.The micro unmanned aerial vehicle remote sensing（micro-UAVRS）system was developing rapidly and widely used to investigate wide range geo-hazards.Based on the practice of using micro-UAVRS in engineering geological investigation and design for emergency control of landslides

the role and advantages of micro-UAVRS was introduced.Then

the new workflow and key technologies & methods were elaborated.Finally

an example was presented.Practice effect indicates that using micro-UAVRS in engineering geological investigation and design for emergency control of landslides could greatly reduce the work time

strength and risks

and was able to significantly increase the efficiency and accuracy of results

and also could improve visual expression of process and results.In a word

the method was effective and capable of achieving the goal of fast &accurate investigation and design for emergency control of landslides.
