This paper presents a component of unified processing for remote sensing image files based on GDAL. The component, which developed an interface specification for unified remote sensing image processing, encapsulates processing operations of remote sensing image files to form an integral, such as GeoTIFF, HDF, SHP, etc.. The component effectively achieves a variety format image files to read and write, save, display, and conversion, to facilitate the development and application of remote sensing image processing system, and reduce the cost of software development.
