内容記述 |
GIS (Geographical Information System) is one of useful tools for disaster prevention. Especially Web GIS based on Internet is a reliable system to collect information of many maps and the attribute data. And Web GIS will be very effective to exchange information. Therefore, the disaster prevention system with Web GIS is required. The target of this study is to establish a system for collecting GIS data by using GPS digital camera. The image of GPS digital camera contains the coordinate of latitude and longitude in EXIF data. GIS data can be established by using the coordinate. However, the coordinate is just position of camera. The coordinate should be converted to point of the object in the taken image. Moreover, disaster area should be mapped on GIS. In this study, converting method for coordinate of the object in GPS camera image will be developed using Digital Surface Model (15 meters grid). The skyline image on the camera point can be simulated using DSM. Direction of the camera can be calculated by image matching with the skyline. After that, disaster area will be mapped. Field surveying with GPS digital camera was carried out for verification of this system. The correct ratio of skyline matching showed about 45%. A incorrect reason might be come from simple shape of skyline. Correct ratio may be raised by using high resolution DSM. In future, correct ratio must be raised, and shape of slope disaster in taken picture is generated as GIS data. |
