The necessity and opportunity of research by fast and efficient remote sensing methods and means derives from the fact that pratological investigation involves a great deal of time and resources, repeated missions on the ground and the involvement of a larger number of specialists. With the advanced technique (remote sensing methods and means), the main purpose of this study is to monitor grassland in the analyzed area and quantify the chlorophyll concentration of plants on the basis of the Normalized Difference V...

The statistical data on the structure of the land fund in Arad County, located in western Romania, highlights changes in the temporal evolution of the surfaces with different uses. One of the causes of these ?migrations? is changing the land use category, for various reasons, legal or technical aspects. In this context, the present paper describes the evolution of the surfaces and the stages that need to be taken to change the land use category, the case study being the ?transformation? from arable into pasture. I...
