Coordinate transformation is a basic function in many softwares.This is true especially in the remote sensing,Geographic Information System (GIS),aerial Photogrammetry software.But,the large-scale matrix operation is the most difficult problem that should be solved in the process of coordinate transformation.The flexibly use of structure array computing in the IDL programming tools can greatly simplify the steps of the calculation to accelerate the speed of image processing.In this study the IDL is used to acquire the latitude and longitude coordinate of all pixel points in one image when only one of the pixel's position and latitude and longitude coordinate is known.
