Overview Of Spatial Methods For Assessing Anthropogenic Land Cover Transformation
Changes in land cover and land use are a space-time process generated by complex patterns and interactions between social, physical, and biological components. The assessment of anthropogenic transformation of landscapes is based on remote sensing data. As a key thematic layer for mapping modern landscapes, geodata on land cover (land cover), obtained as a result of processing satellite images from various survey vehicles and systems, are usually used. To quantify the transformation, formulas and a calculation scheme based on the values of the areas in different boundaries were developed. Databases on land cover and land use were analyzed for a certain time interval. This can be a 5, 10, 15, 20 year period. In 1970-1990, for a specific year (date), data was obtained by interpreting scanned images on the monitor screen (resolution 0.5 m x 0.5 m pixels) and ortho photos (resolution 2 m x 2 m pixels), respectively. More recent values (starting from 2014) are obtained using a combination of digital classification and interpretation of spot data. This paper is a review of methods for assessing land cover transformations. The authors were able to identify the main approaches to the quantitative assessment of changes and the evolution of approaches to the study of this topic since the 1990s.
