The img format is a format for image files. It has high compression efficiency. The IMG format supports images of any size. img image file format, the image data is stored in a similar two-dimensional array format. The first two positions in the first line store the width of the image, the next two positions store the height of the image, the next position stores the gray level of the image, and all the remaining positions store All are grayscale of images

IMG data has the following characteristics:

Multiple information of images are stored together. Remote sensing data includes image data, positioning data, sensor information and other information. Generally, the file header and image data are stored separately, while the Img file stores all types of data in one file.

Data is stored in nodes. The position of various data in the file is not fixed, but is organized through the interrelationship of nodes.

Image data is stored in blocks. Blocked storage reduces the consumption of image reading system resources, thereby greatly accelerating the speed of image display; at the same time, it avoids the impact of large data volume on the efficiency of image processing algorithms.
