Method for providing services on online geometric correction using GCP chips

摘要

Disclosed is a method for providing services on online geometric correction using, in which information related with GCP (Ground Control Point) used for correcting geometric distortion of an image collected by an aircraft or a satellite are transmitted online through Internet network, thereby allowing a user at a remote place to perform geometric correction or ortho-rectification. In the geometric correction process, the image information related with the GCP is provided but the precise geographic coordinate of the GCP itself is not provided to thereby maintain the secretion of detailed geographic information.
