Remote sensing is a useful technology as a superior to other methods thanks to
features like vast and integrated view of the area, repeatability, accessibility and high
precision of information, and saving in time. Vegetation index is extensively used
nowadays in different continental, regional, and areal scales. Due to excessive use of
natural resources, area of landscapes has been changing day to day and updating of the
maps is a costly and time-consuming task. Thus, many of the well-developed countries
take benefit of satellite data at different levels. The analysed factors included 1-
preparation of vegetation and land use maps of North Khuzestan; 2- assessment of
biological potential in agriculture development of the studied area using WLC and
weighted overlay technique.
Based on the acquired results and performed computations, it was demonstrated the
variations in the pasture and agriculture soil during the years from 2003 to 2014 were
19 percent and a significant reduction is observed in this part of land use. The changes
between the years 2014 to 2016 were equal to approximately 11 percent according to
the computations. This value is remarkably high and indicates intensity of changes
during the recent years.
