The present invention is the location of the expedition body of minerals, faults, discontinuities, oil, limestone cavities, too, groundwater, etc. pyegaeng present in underground by using the gravitational or magnetic sensing data obtained through various methods, such as the ground, aircraft, satellites 2 relates to a process to obtain a dimensionally, and more particularly, gravity or magnetic survey data traveling direction component existing Euler to identify the position of the sensing object by using the depth-direction component (Z-axis) to (X-axis) in - deconvolution to modify and improve the more accurately the position of the upper body expedition, and a method to obtain a two-dimensional position of the body to find the expedition objectively. ; Method using a gravity or magnetic survey data of the present invention to obtain the two-dimensional position of the upper body is expedition, ; (A) step of the gridded survey data to gridded at intervals along the measuring direction of the sensing data of measuring a gravity or magnetic force value of the predetermined interval; ; (B) a gridded sensing data of the sensing data to discern the direction and amount of change in the change amount separated in the vertical direction of the horizontal separation phase; ; (C) determining the size of the window and, by applying it to the equation (6) to a fixed position of the possible existence Euler finding expedition upper-stage deconvolution performed; comprises a, ; Wherein (c) by varying the size of the window in step Euler - and characterized in that the deconvolution performed several times, ; (D) determining the position (c) that is the highest frequency period by analyzing the presence of a possible location expedition body obtained through the steps to the position of the upper body expedition; and further comprising a. ; Gravity, magnetism, exploration data, groundwater, fault, joint, pyegaeng lattice, windows, Euler-deconvolution
