Study on Forest Vegetation Using Landsat Time Series
Earth observation provides unique information for the purpose of observing dynamic phenomena occurring on the surface of the Earth, especially for evaluating the changes in the forest vegetation. This study is focused on the evaluation of forest vegetation changes that took place between 1992 and 2015 in the Low Tatras National Park in Slovakia, using time series on Landsat 4, 5, 7, and 8 data.
It has been found that although Landsat data allows us to remotely observe the Earth for the past 47 years (since 1972), perspectives can be seen in the data of Sentinel-2 produced by Copernicus. The advantage of the Sentinel-2 data are
- the higher spatial resolution (10 m for VIS/NIR and 20 m for NIR and SWIR bands) and
- the higher temporal resolution.
Such a high temporal and spatial resolution enables advanced information about dynamic changes in the forest under climate changes.
