The purpose of this paper is design and implement the invisible depth analysis tools. The developed algorithm was basically used reference plan method and to remove first step errors we mix-used point-to-point method. and we consider error due to curvature and refraction for large scale analysis. The final algorithm was developed as ArcToolBox tools, which can be considered convenient and public use as well; as result it reduced experimental errors as compared with conventional method and makes possible high resolution analysis for large scale site.
