Abstract: Traditional desktop style remote sensing image processing software is increasingly becoming powerful and widely used. TITAN Image, one of the excellent homemade desktop remote sensing image processing software, is powerful and includes lots of novel algorithms. However, TITAN Image which is a centralized constructed desktop software system lacks sharing mechanism. And this limits the development of system on many aspects such as functionality and performance. Also it makes itself inadaptable with the further development of remote sensing technique. Then the development of the grid computing technique provides an effective approach to realize the sharing and integration of remote sensing image processing software. Through grid services implementation of TITAN software, its traditional centralized software structure would be eliminated and its algorithms would be integrated into grid effectively. Accordingly, the cross-plat and cross-region sharing and cooperation of image processing algorithms will be realized. Therefore, based on the research on the characteristic of TITAN software package, a technical strategy of grid services implementation of TITAN software package in Spatial Information Grid using the open resource sharing model of grid will be given in this paper.
