GEOINFORMATION MAPPING OF ANTHROPOGENICALLY TRANSFORMED LANDSCAPES OF BILA TSERKVA (UKRAINE)

Abstract

Aim of the study The main purpose of the study is the analysis and assessment of anthropogenically transformed landscapes of Bila Tserkva (Ukraine) based on a combination of remote sensing methods and GIS mapping. Material and methods Usage of geoinformatics methods for mapping anthropogenically transformed landscapes of Bila Tserkva is studied. The data was downloaded and processed using the QGIS Semi-Automatic Classification Plugin for the supervised classification of remote sensing data. Satellite images were radiometrically calibrated and atmospherically corrected, followed by a controlled classification with signature creation, visualization of spectral profiles, quality assessment and post-processing. Results and conclusion The main methods of landscape research are analyzed. The conclusion is made about the expediency of using spectrophotometry of satellite images in order to identify different types of landscapes based on satellite data. A supervised classification of satellite images different-time images was performed, as a result of which the main Bila Tserkva landscape types were identified. Those identified types are: water bodies, vegetation (grass, forest, parks), urban areas, and bare soils. Spatio-temporal changes of landscapes are studied and these changes are described in quantitative indicators.
