In this work, we focus on the restoration of forests in the Jizera Mountains. Your task is to observe this area in two frames from different periods and to compare the development of this site in terms of mining, development, changes in agriculture and land management, based on the Remote Sensing methods. The area is located in the northern, central part of the Czech Republic. It is a border area that is specific to its mountainous surface. Larger towns can be named Liberec or Jablonec nad Nisou. The region is affected by significant changes in the forest ecosystems and, thus, an interesting study area especially for applying remote sensing methods.
