Vegetation classification in a subtropical region with Sentinel-2 time series data and deep learning
Publikováno v:
Geo-spatial Information Science, Pp 1-19 (2024)
Preparing regular time series optical remote sensing data is a difficult task due to the influences of frequently cloudy and rainy days. The irregular data and their forms severely limit the data’s ability to be analyzed and modeled for vegetation
