1. Average altitude is calculated using each temporary photo- 
graphy flight plan line. 
. Photography flight plan line is determined with the flight 
altitude according to the average altitude. A highest altitude 
position is detected in a sidelap zone. 
3. The interval of a photography flight plan line is adjusted so 
that a sidelap may maintain the specified rate of a sidelap.

1.3 Flight altitude priority 
Flight altitude priority is generated with the following concept 
in consideration of geographical feature. 
1.Flight datum plane is determined using the average altitude in 
the map creation range. 
2.Temporary photography flight plan line is calculated from 
Flight datum plane. A highest altitude position is detected in a 
sidelap zone. 
3.The interval of photography flight plan line is adjusted so that 
a sidelap may maintain the specified rate of a lap on the highest 
altitude position. 
A conceptual figure is shown in Figure 2.

Figure 3. Fix flight datum plane concept 
A photography flight plan line is determined using light 
condition without taking into consideration change of the rate of 
a lap by geographical feature. 
A conceptual figure is shown in Figure 3. 
1.5 Common algorithm 
The extension of a photography flight plan line to the map 
creation range adjusts in consideration of control point for aerial 
triangulation as a precondition which satisfies light condition, 
after calculating number of exposure stations. 
1.6 Independent line movement 
It made it possible to move to the perpendicular direction of a 
plan line, inheriting each generating method, in order to enable 
artificial fine tuning of a photography flight plan line. 
In the case of movement, the sidelap of the both sides of a flight 
plan line is displayed on a real time. It is warned when a sidelap 
becomes below a regulation value. 
2. APPLICATION 
2.1 Flight simulation 
The flight simulation was created as application to visualization 
using the photography flight plan line. Geographical feature 
was reproduced from the geographical feature information 
currently used for a photography flight plan, and the simulation 
was performed. 
Simulation result is shown in Figure 4.

3. CONCLUSION 
It became possible to create without depending for a highly 
precise flight plan map on experience easily by development of 
Management And Plan system for MAP production. 
There are issues, however, for further work. These problems are 
a development of optimal generating algorithm for photography 
flight plan, and photography from which height is different.
