报告简介：Multi-temporal remote sensing data analysis has been increasingly used to characterize land-cover and monitor vegetation conditions at regional and global scales. For agricultural applications, multi-temporal MODIS (Moderate Resolution Imaging Spectroradiometer) data are now routinely used for crop-specific mapping, crop yield forecasting, crop stress detection, crop phenology detection, and evapotranspiration estimation (ET). Recent research has also shown that multi-sensor data fusion at Landsat spatial scale (e.g., 30m) can greatly improve the temporal frequency of observation, a critical component for many RS-based analysis and modeling of agricultural system. This presentation will draw examples from the author's experiences in cropland mapping, yield forecasting, ET estimation, and watershed modeling efforts in the Great Lakes Basin and the Midwestern region of the United States. Main challenges and opportunities in data quality, data volume, and data mining will be discussed under a multi-temporal remote sensing framework.
