National Geographical Organization Scientific- Research Quarterly of Geographical Data (SEPEHR) 2588-3860 17 68 2009 01 20 Detection of Land Cover Change and Land Use Change Based on Remote Sensing Sciences Detection of Land Cover Change and Land Use Change Based on Remote Sensing Sciences 13 18 27446 FA Alirerza Sofianian Assistant Professor of Environmental Science, Faculty of Natural Resources, Isfahan University of Technology Samereh Falahatkar Master of Environmental Science, Faculty of Natural Resources, Isfahan University of Technology Journal Article 2008 08 18 Remote sensing and GIS are widely used in identifying and analyzing land use change. Satellite remote sensing provides multi-time and multi-spectral data that can be used to quantify the type and amount and position of land use change. Furthermore, the GIS also provides a flexible environment for displaying, storing and analyzing the digital data needed to detect changes. Since environmental changes are important in order to give a general impression of the region's environment and build credible hypotheses based on sustainable development, detecting these changes is an important process in the monitoring and management of natural resources and urban development. Detection of changes is also considered as a part of modern science due to dependence on remote sensing sciences and GIS. With the rapid growth of cities in recent years, the recognition of their biophysical compounds and their dynamism is of particular importance and is considered as an important research topic. The operations that are carried out in the course of digital analysis and interpretation of satellite data and with the aim of identifying and distinguishing ground phenomena can be summarized in three stages of initial surveys and information preparation, classification of information and finalized reviews and processing. Geometric correction of images and their classification based on existing methods and algorithms, and the accuracy of production maps, and finally comparing the maps at different times are among the stages of detecting changes. In the present study, we try to describe the steps briefly. Remote sensing and GIS are widely used in identifying and analyzing land use change.
