3. ACCURACY ANALYSIS 
In this research, the digital mapping of large-scale using aerial 
digital camera imagery which was improved of practical 
efficiency compared with existing analogue method was 
performed. And it would be present foundation data and 
reinvigorate relative industry. For this purpose, digital 
restitution using digital camera imagery was constructed. And it 
was compared with a scale of 1 to 1,000 digital map which was 
produced by Korea National Geographic Information Institute 
and accuracy analysis of it was conducted. 
Figure 5 shows a distribution chart of check points for accuracy 
analysis. Table 2 shows deviations of check points. And figure 
6 shows accuracy of product.
