Current lanscape in the neighbourhood of open cast mines in northern Bohemia

Abstract

The classification of the landscape through different types of uses, it will be the basis of this classification of the work area. This study will explain in detail the method by which to classify the composition land units and the resulting land use composition. Using the GIS (geographic information system that integrates hardware, software and data for capturing, managing, analyzing and displaying all forms of geographically referenced information) with the orthophotos identify are identified the different types of land use of the work area. Land uses refer to the existing activity in this area at the time. GIS have proved to be very effective not only for determining the different types of landuse in an area, but also for the classification collecting valuable information for interpreting and it can determine trends in land use by comparing these maps from different years, very useful to see how it evolves and how it will do in the future, allowing to make decisions in advance. For land classification there are several methods, some also work using the GIS computer program but instead of classifying the land regarding its use, classified by their landscape value, others through the use of land of this area not only the actual but also in past years. In this project included different methods of classification, with a brief explanation of their methodology. Although some of these methods in addition to making the corresponding classification are also methods of analysis of changes in the work area over time. In this case working only with a layer of a specific year and I did not do this kind of study. Therefore, after the vectorization and correction of the original layer, I made an assessment of the data, grouped the values of land use in stable and unstable. Commenting on the corrected changes, the original data and the proportion of different land use types, I mean making an ecological assessment, including the impacts of open pit mining and possible corrective measures both during activity and abandonment.
