Some results of comparison on analytical aerotriangulation procedure as a branch of geodetic surveyings are given to each step of conventional geodetic triangulation and analogue aerotriangulation. Several cautions on the treatment of the analytical aerotriangulation to the present methods performed in Japan, are necessary from the geodetic point of view, such as the procedures corresponding to station adjustment, side equation adjustment, in addition to the corrections for atmospheric refraction and the earth curvature in the conventional geodetic triangulation. To get further precise results by the analytical aerotriangulation, more rigorous treatments on calibration of comparator and observation of image should be required .
