Forest cover change detection by satellite scenes
Objectives
06.07.2009
Since the beginning of the 21st century, the forests in Slovakia - and especially spruce forests - are under serious pressure from windstorms and subsequent bark beetle outbreaks. These injurious agents usually affects forest stands at a scale which enables change detection even from the space. Therefore, the main objective of this web site is to visualize actual and historical satellite compositions of Slovak territory in order to allow users to monitor forest stands state and to identify ongoing changes.

Target groups:
  • state forestry administration
  • forest managers

Map applications The web map applications are a key part of this web site. Map applications visualize actual and historical compositions of satellite scens, which are usefull for visual interpretations of forest cover changes.
The applications run in web browser. The boundaries of state forestry administration units (OLÚ), forest districts (LHC) and forest stands (JPRL) can be displayed as well in order to localize identified changes.

News
23.11.2016
Classification of forest stand state and the mosaics of satellite scenes from 2016 were updated in the map applications 2, 3 a 4. Both layers, derived from Sentinel 2 scenes, have spatial resolution of 10 meters.
