• Abstract:

  The use of existing technologies within the science of remote sensing has increasingly contributed to the development of agriculture. Thus, our objective with this research was to compare performance to quality read between active and passive optics sensors are considerably greater to monitor spectral behavior of rice at different dates during their growth stages. This project will present correlations between active optical sensors with Sentinel 2 (S-2) satellite spectral bands. The vegetation indices to be used were: NDVI and CIRE. All the data simple linear regression and Pearson correlations were performed to compare active and passive sensors (satellite imageries data) with active crop canopy sensor technology. The averaged data were used along rice phenology to illustrate the dynamic of both sensors during the entire rice season. The active sensor presented better results than the passive sensor due to its being more stable for data collection under some different weather conditions.
