The Study on the Viewshed Analysis and the Estimation of Proper Number of Forest Fire Surveillance Cameras (Focusing on Samcheok-Si)

This study suggested the proper number of the forest fire surveillance cameras. The visualities and effectiveness of surveillance cameras were analyzed according to basic administrative units in Samcheok City. First, we assessed the visual range and effectiveness of each surveillance camera. The results showed that visibility of the seventh surveillance camera was narrow and overlapped because of short distance from other camera. Consequently, The results of these analysis shows that the cameras which had a poor visual range located must be relocated in area where that had a high visual range. As new surveillance cameras are installed in this region, the location of these would have to be considered by these conditions; the overlapping of visibility with other cameras or other organizations, the adequacy of its location, etc. And over 32 surveillance camera would be need for the most effective monitoring in Samcheok City. These results would be utilized for improving an efficiency of surveillance camera and forest fire management techniques.
