The remote sensing methods together with the GNSS and geoinformation technologies play an important role in the terrain survey. The...

The morphologic and morphometric landform information plays a significant role in the spatial and temporal analysis and modeling of the landscape and affects the course of the natural processes. The geoinformation technologies provide for performing digital terrain analysis and extraction of a series of morphometric parameters and landform elements...

The significance of the non-destructive methods in archaeology has grown up in the recent years and the application of remote sensing and GIS technologies has become more important. Preservation and conservation of the archaeological sites has always been one of the main goals in the archaeology due to the fact that the sites are exposed to many de...

up to 200 words /Times New Roman, 10, Italic/ Historical GIS is a relatively new interdisciplinary field, which has been developing rapidly over the last 10 years. The main functional capabilities of GIS technologies which contributes to historical research are mapping; spatial analysis; building geodatabases, integrating, storing and managing vari...
