- Fundamental Study on Construction of Hazard Map Causing by Landslide Area Ⅲ--Development of Easy Method of Forecasting of Landslide Area in Kanoya City and Kagoshima City Using the Spectral Image Data
Landslides on the mountainous area have been increasing in recent years, because of a heavy rain caused by abnormal weather. It is anxious earnestly to solve to construction of hazard map by landslide area. Therefore, we have studied to those problems by the remote sensing technique. It was reported that satellite data and aerial photographs are effective to construction of this hazard map. Comparing these data, digital camera has a following merits, time intervals to take the data, ground resolution, and easy to obtaining data. This study was aimed to make hazard map using digital camera with practical and easy method. Under weather conditions and mountainous slope conditions were differed, the spectral images were taken by digital camera. These images were processed according with water content using ratio index. After these results were overlapped, the possibility of detection of hazardous area was shown.
