Stereo photograph(left side)
3.3 Preparation of the topographic map
The photograph was expanded to the Ad size, and
printed on printing paper. Coordinates of the
measurement point on the photograph were
measured by the digitizer, and the topographic
map was made based on the data. The
measurement point on the photograph were
white boards set up beforehand on the landslide
area, a scattered rock, etc. and those three
dimension positions were calculated. The
topographic map made by the inertia
photogrammetric camera is shown in Figurell,
and the topographic map described on the basis of
the data of the Total Station is shown in
Figure12. The contour line was depicted using
Arc/view which was the software of GIS. The
contour line intervals drawn in the topographic

Stereo photograph(right side)
Figure10. Photographed stereo photograph
map are three-meters interval. The Figure
expresses the center part in the photograph in
Figurel0, within the range of 35 meters in length
and 45 meters in width. The square seals in the
topographic map are the white board, and the black
round seals in Figurell are rock etc. measured by
the inertial photogrammetric camera system. The
black triangular seals in Figurel2 are points
measured with the Total Station as well as a white
board. By comparing both Figures it can be proved
that the data in Figure12 has deviated horizontally
5 meter to the right compared to Figurell
according to the slippage of the position of the white
board It is thought that this reason is that the
Total Station is not corresponding to the
coordinates of the inertia device. However, it is
understood that both figures draw almost the same
contour line chart.
