While using wire projection method to draw a stratigraphic section with actual measurements,the section drawn could not reflect the real information due to the deviation between the total azimuth of the wire and the actual measured azimuth.According to recent methods used for stratigraphic section survey,the authors brought forward and discussed two correction approaches,the DouglasPeucker algorithm and linear regression.The latter was applied for the measured stratigraphic section of main ore body I in Pangxidong Ag(Au) deposit.
