Environmental Assessment of Geological Hazards Related to Sulphur Exploration in Poland Using Remote Sensing and GIS

Intensive exploitation of sulphur in Poland during the past 25 years has caused many changes in natural ecosystems. Different data were applied for analysis of these changes: multi-temporal aerial photos, Landsat 5 TM images, topographic, geological, hydrogeological maps etc. The aim of the project was to develop an efficient and cost-effective methodology for detection of geoenvironmental change, using remote sensing data and GIS, and to perform comprehensive analysis of land use, pollution of underground and surface waters, geological conditions, and terrain subsidence above the exploited mining sites.
