摘　　要：利用Map GIS和Excel软件相结合,在勘探线上设置若干特征点,运用特定的数学公式,将原始特征点的坐标转换为具有距离和高程意义的新坐标系统,由点及线到面,绘制具有高精度的勘探线剖面图。In combination of Map GIS and Excel, feature points were set up on prospecting lines. By specific mathematics formulas, the coordinates of original feature points were transformed into the new coordinates with distance and elevation, from point to line and to plane, to draw the prospecting line profile map with high precision.
