The position and the area of any spot can be determined in different modes and using satellite image is one of them. For this mode there are many applications like in determining the positions and the areas of the water pollution spots (the rivers, the streams, the marshes….etc.), the air pollution spots, for different agriculture lands ….etc. In this mode, the area of any spot on the satellite image can be determined by finding the planimetric (Grid) coordinates (x, y) for the periphery points of the spot using ERDAS Imagine Software Programme Ver. 9.2 if the satellite image is rectified , but if it isn’t a special method is used for the rectification of the satellite image then the positions and the areas can be determined.
