emergency response. A disaster management system based on 
the real-time aerial mapping system is shown in Figure 7. This 
system is composed of a field sector, aerial sector, transmission 
sector, data processing sector, data analysis sector, and data 
supply sector. Among the six sectors, the key three sectors are 
supported by the real-time aerial mapping system.

3. PRELIMINARY SYSTEM DESIGN 
3.1 Requirements of Overall System 
Four application scenarios based on emergency mapping are 
assumed. They are real-time fire monitoring, investigating 
damage of floods, periodic monitoring, and urban development 
analysis. According to these scenarios, we have derived overall 
system requirements of the real-time aerial mapping system to 
be developed in the project. This derivation process is 
summarized in Figure 8. 
Using the process, we have determined the requirements about 
the platform operation and the quality of the spatial information. 
Table 4 shows some critical requirements for platform 
operation and Table 5 does the required resolution of the 
geospatial information.

3.2 Configuration 
We propose two types of real-time aerial mapping systems. One 
is high grade and the other is medium grade in terms of quality 
and price. The high grade system is assumed to operate in not 
only settled but also unsettled weather. So this system mainly is 
targeted on disaster/accident management with unsettled 
weather. But the medium grade system can only operate in 
settled weather. Therefore this system is usually targeted on 
detection of unauthorized buildings or illegal discharging of 
waste water in fine weather. 
Table 6 and Table 7 show the preliminary configurations of two 
systems. 
Schiebel’s Camcopter S-100 is adopted as the UAV platform of 
the high grade system. As the platform’s maximum payload is 
50kg, a laser scanner can be mounted on the platform which 
holds a top position in massive sensor list. 
NEO S-300 manufactured by Swiss UAV is adopted as the 
UAV platform of the medium grade system. The platform’s
