Remote Sens.2015, 7(2), 1482-1503;https://doi.org/10.3390/rs70201482

29 January 2015

Agriculture is a highly dynamic process in space and time, with many applications requiring data with both a relatively high temporal resolution (at least every 8 days) and fine-to-moderate (FTM < 100 m) spatial resolution. The relatively infrequ...
