The PCI Geomatica software of Canada widely used in China allows users to define a coordinate. As much of the image processing work is based on Xi'an 80 coordinate, it is very important for us to define a coordinate needed in daily work. This paper has successfully defined the Xi'an 80 coordinate projection parameter which can ensure the effectiveness in practical work.
