摘要
Abstract
This study,taking Jiangxi Province as a test area,was to investigate how to comprehensively use RS,GIS and GPS (3S) technique in monitoring crop growth. Due to the complex hilly terrain in southern China,land use/cover information and GPS measurements were both applied for interpretation of NOAA/AVHRR,extraction of vegetation index and then observation of seedling's growing status for late rice of double harvest. Finally in terms of iterative auto-organized analysis,monitoring of rice growth vigour could be realized from corresponding phase-specific NOAA/AVHRR when there are no GPS measurements. Results show that combination of the data on geographical information including digital elevation and land use type with GPS measurements may be appropriate and feasible to better utilization of NOAA/AVHHR data.
