Project goals

The study will be focused on:

  • Testing the latest Earth observation (EO) techniques, models and field spectroscopy in order to adjust such modern methods to the specific natural conditions of the Czech Republic.
  • Improving capabilities of the hyperspectral imagery processing approaches applied to areas heavily affected by long-term intensive mining activities.

Principle Objectives

To develop and/or improve methods for the extraction of information and knowledge from imaging spectroscopy data, focusing on mining and environmental protection related phenomena. To use high resolution hyperspectral data in order to answer following key issues:

  1. Spatial mapping of mineral and rock indices enhancing the different sedimentary formations presented at mining site includes both, grain size mapping (proportion of clay, silt, sand and pebble fraction) and mineral mapping (quartz, Ca-Fe-Mg carbonates, sulphates, clay minerals, coal and bitumen).
  2. Map the current extend of area affected by mining activities (tailing pounds, acid and heavy metal polluted zones, irritated vegetation, and changes in protection zones of water resources) as the key players in surface water/ground water management and preservation of hot springs in the Czech spa region of Karlovy Vary.
  3. To find relationships between irritation originator and consequential environmental disturbances of vegetation. This issue will be focused on observation of coniferous (specifically Norway spruce) and pioneer vegetation status.
  4. Integrated data analyses based on the thematic maps resulting from the aerial and insitu hyperspectral data (putting together 1 – 3) - Implementing new mapping techniques providing a high level of spatial and spectral distinction among all the major environmental components, present at the open pit mine area and its closest surrounding (e.g., mineral extraction, waste extraction, contaminated water identification, chlorophyll, cellulose and lignin content in vegetation). Besides the identification of content changes of selected indicative materials, these techniques allow studying dynamic phenomena by identification and quantification of unchanged primary materials, semi-products and end products involved in physical - chemical reactions depending on and responding to the specific conditions they occur at a specific mining site. Such modern mapping techniques can lead to integrated data analysis resulting from the assessment of the environmental state and risk of mining sites and surrounding environment.
  5. To develop the key components of the decision-making tools and methods. Proper exploitation of these data can be used in sustainable information systems, which can make an interface for implementing the Czech/EU directive on mining waste management.
