The objective of this study was to develop a reliable field monitoring system combining helicopter-based and satellite-based remote sensing. In this research, multi-spectral imageries were used that was taken by SPOT5, QuickBird-2 and helicopter. These imageries were synchronously taken. As every vision covers the same wavelength range and takes same objects, the color information of the satellite and helicopter images would be integrated. The relation of the information on NDVI was examined. There was a high correlation between satellite-based NDVI and helicopter-based NDVI. The R2 value was 0.81 between helicopter-based NDVI and Quickbird-2 satellite-based NDVI. Therefore, it was possible to do revision of the color information on the relative satellite imageries in using helicopter imageries. Using these color information, the field status (moisture content of wheat ear) can be estimated. Combined Helicopter-based NDVI and satellite-based NDVI, it became possible to estimate the wide range in high accuracy and high efficiency.
