To achieve the preliminary land unit classification, a set of updated multispectral satellite images was acquired . A set of Sentinel-2 (from January to February 2020 interval time) images covering integrally the complexes of the project area with a spatial resolution of 10m per pixel has been processed using Near infrared, green and blue spectral band combination) and analyzed using a GIS software. The analysis of the images helps to classify the areas at fourth levels:
- Soil Region (1:3M scale)
- System (1:1M scale)
- Subsystems (1:500k scale)
- Land Unit (1:250k scale)
Further based on the photointerpretation, the morphologic and physiographic analysis the homogenous land units are defined. First, a general overview of the study area done based on bibliographic material concerning existing soil surveys, geography, geology, climate, agriculture, vegetation and soil characteristics.

Particularly, in this case a mixed descending and ascendi...
