Research Conclusions: Fabrication of aerial or satellite digital positive photography image pattern for railway by large-scale has the features of short period，becoming effective rapidly ， saving cost ， lowering the requirement for needing special technical devices and increasing the reality of information. The good economic and social benefits can be created if the digital positive photography image pattern is used for railway plan，railway design ， requisition of land for railway ， railway track maintenance and management of land. The vivid，rich and high geographic accurate information necessary for design can be provided for entire design of new railway line with all kinds of scaled positive photography image pattern made from high-resolution satellite image or aerophotographic image. If the Digital Elevation Model and positive photography image pattern are coincided each other along with all models of railway equipments，the 3-dimensional photography image of designed area can be obtained，besides，the real 3-dimensional landscape image can be realized if a flying route is added over the designed route.
