LAND SLIDE MEASURING METHOD USING TOTAL STATION

摘要

PROBLEM TO BE SOLVED: To provide a land slide measuring method using total station capable of performing a precise land slide measurement at low cost.;SOLUTION: Light reflecting members 11-18 are set in a required number of measuring points P1-P8 within a land slide quantity measuring object area A, and an automatic tracking type total station 3 is set out of the area A. For each of the measuring points P1-P8 that are setting points of the light reflecting members 11-18, one set of position data DP showing three-dimensional coordinate values corrected with weather data DW is obtained by the total station 3. Mesh-like 2-point distances among the light reflecting members 11-18 are computed based on the resulting one set of position data DP, and the land slide quantity in each measuring point P1-P8 is obtained from the change with time of the 2-point distances.;COPYRIGHT: (C)2006,JPO&NCIPI
