| Research Abstract |
This project composed of two main assignments. The first one is to clarify developmental changes of land-cover observed on satellite data. The second one is to clarify seasonal or annual land-cover changes on satellite data. We used LANDSAT/TM data for this study, to analyze the changes of spectral reflectance values.
To identify the developmental change on the LANDSAT data, it is important to confirm land use on each point. We analyzed the change of land use data between 1975 and 1998 by using GIS Map, and compared the change of spectral reflectance values between 1986 and 1999. We concluded that the function of ndvi value and b1value shows best identification, in Dazaifu city area.
Land-cover data, analyzed from satellite spectral reflectance data, shows seasonal or annual change. We checked the phenomena to analyze 2001 LANDSAT/TM data. Land-cover data clarify that the spectral reflectance value on paddy field changes almost same value on urban district between autumn to winter. Therefore, it is important to check seasonal change of land-cover to analyze satellite data.
