چکیده مقاله :
Remote sensing due to extensive coverage, high separation capacity and low cost of data acquisition from the ground as an efficient tool , has played an important role in the field of Earth science research and environmental monitoring. One of the most important applications of remote sensing are the ability to detect changes. Today's high-resolution satellite imagery makes it possible for these images to be used to produce urban maps or updating them to identify changes in urban environments. Precise and timely diagnosis changes, both locally and globally, are important for the management of the optimal use of resources. The purpose of this article is introducing all methods for detecting land use change using remote sensing data that has been presented so far. In this regard, these methods are examined and the advantages and disadvantages of each expression are expressed. Also, these methods are compared so that the user can, according to the application, select the appropriate method in this direction.
