Evaluation and Analysis of Horizontal Extension of Ahwaz Metropolis from 1973 to 2013
The present study seeks to use the capability of remote sensing software and GIS to detect changes in land cover and land use, as well as changes in the dynamic growth of Ahwaz's territory and its ecological condition based on information obtained from satellite data. This research is an applied design. The data collection method includes library, field and aerial photography and remote sensing studies. The data were collected from detailed and master urban plans, land preparation, population and housing census results, statistical yearbooks and other valid sources. Remote sensing data that is required in digital form is provided through the Remote Sensing Center. The software used is Geomatica P.C.I, Arc GIS, Arc view, Auto cad, Excell. In this study, geomorphology map, landforms and phenomena have been identified and interpreted. The results showed that Ahwaz city with an area of 138.12 km2 in 1973 had 16% change. From 1973 to 1990, the area of Ahvaz has reached 188.3, and from 1990 to 2005, Ahvaz has had the largest change as 260.13 km2 compared to other years. Ahwaz did not change much between 2005 and 2013.
