Estimation of rice growth status, protein content and yield prediction using multi-satellite data

摘要

By using the image data of Landsat 7, 8 and Sentinel 2A, authors monitored the rice growth and estimated chlorophyll content in leaves of rice at brand rice production area of northeast Japan in high temporal resolution. The leaf chlorophyll content estimated from the satellite was converted from NDVI to SPAD value. Also, the most important brown rice protein value for rice quality was converted from NDVI and made available one month before harvest.
