Abstract：Using high-precision remote data (resolution with sub-meter) to detect relevant information can evaluate geophone array and select favorable geophone planting position, which can not only be used to evaluate that the design plan can be implemented or not and auxiliary select appropriate geophone array pattern, but also optimize the central point of geophone array point by point before field measurement, reaching the goal improving receiving condition and practicableness of geometry and ensuring the quality of signal received by geophone. Using high-precision remote data to detect relevant information can evaluate the factors affecting the quality of signal received by geophone, the corresponding remote information is mainly used for evaluation in following three aspects: ①using DEM and slope to compute flatness and expanding capacity (array expanding degree) within geophone array pattern; ②using difference of elevation, slope, damp and surface porosity within an array in region of geophone array to evaluate good or bad couple condition (array superior degree); ③using relevant information detected by integrative high-precision image and DEM to partition the area that should be avoided in the work zone and forbidden zone of operation that is not corresponding to HSE standard (practicableness). The analysis of practical case showed that the flatness and expanding degree of planting points within a geophone array has been improved by using remote image to select geophone array and planting central of geophone array, playing important role reducing field work efforts, improving work efficiency and practicing economy of cost
