Preliminary scope of work |
Diplomová práce se zaměřuje na hodnocení obnovy lesních ekosystémů po proběhlých kůrovcových kalamitách pomocí družicových dat. Využito bude volně dostupných optických i radarových družicových dat Sentinel (Sentinel-1 a Sentinel-2). Hlavním cílem práce je určení míst obnovy lesů a jejich vývojových stádií. Hlavními zkoumanými charakteristikami bude výška, hustota a druhovostní složení obnovovaného lesního porostu. Bude vytvořena metodika/algoritmus ve volně dostupném výzkumném prostředí Google Earth Engine na vyhodnocení obnovy s využitím časových řad družicových snímků. |
Preliminary scope of work in English |
The master thesis focuses on the assessment of forest ecosystem recovery after bark beetle outbreaks using satellite data. It will use open optical and SAR Sentinel satellite data (Sentinel-1 and Sentinel-2). The main objective of the work is to identify forest recovery areas and their development stages. The main characteristics to be investigated are height, density and species composition of the regenerating forest stand. A methodology/algorithm will be developed in the freely available research platform Google Earth Engine to assess restoration using time series of satellite data. |
