Figure 8. Comparing Observed Value Graph 
about 200 pictures, the weight is lessen than 3kg so that one 
person can operate alone. 
The third, geo information can be gained and processed easily 
by Development of Positioning Information realized Digital 
Close-Range Photogrammetric System so that financial damage 
is can be decreased. 
The forth, it can be used for developing cities as element data 
by monitoring geo information systematically. 
In the future, we will improve civil industry and other industries 
by inventing high detail GPS receiver so that positional 
accuracy could be lessen than 3cm. 
4. CONCLUSIONS 
In this research, the point of development of Positioning 
Information realized Digital Close-Range Photogrammetric 
System is to increase efficiency when renewing old result of 
digital map for changed topography rapidly and when you need 
real time information. And the results are : 
The first, in comparison with Ordinary System surveying 
results, latitude error is 19.383m, longitude error is 9.090m and 
Altitude error is 8.413m. However development system has 
shown that latitude error is 7.203m, longitude error is 4.544m 
and altitude error is 5.735m. 
The second, consumption of battery is one of the most 
important things for photogrammetry, the old system can 
observe about 30 pictures but development system can observe
