【 摘 要 】

The objective of this study is to investigate the potential application of Spot-5 multispectral satellite data in monitoring rice cultivation areas in IADA (Integrated Agriculture Development Area) located at Kerian District, Perak Malaysia. Information of the rice cultivation areas is a global economic and environmental significance. Multi-spectral images acquired at high spatial resolution are an important tool, especially in agricultural applications. This paper addresses the relationship between normalize difference vegetation index (NDVI) and ancillary data acquired from Farmers Organization Authority (PPK) for 217 farmer's field in IADA Kerian. The results indicated that NDVI range 0.62-0.75 has a strong positive relationship with the ground survey area estimation with (r 0.85; p 20.722). The r2value of 0.722 indicated a statistically significant linear relationship between the rice area estimate using NDVI range 0.62-0.75 and on the ground surveyed data for 217 farmers' fields. The equation of unstandardized distribution can be described as Yˆ=0.0197+0.852x. The equation for standardized regression formula for this distribution is Yˆ= 0.850x. Thus, the results indicate that 60-75 days of rice area can be estimated from the following equation Yˆ=0.197+0.852x, where Yˆ is the predicted rice area and x is area calculated using NDVI range 0.62-0.75 in IADA Kerian Perak Malaysia. The results appear promising and rice mapping operations using SPOT-5 multispectral image data can be foreseen.
