Roads are the mainstay of any new development and it was requirement to be located occur seamless and optimal connection. Determining the route location is one of the biggest planning problems facing us at present while constructing new one. It was involved to evaluate of different agents in order to obtain optimal and least cost place. The goal of this investigation was carried out to perform a spatial sample that uses multiple standards with different weights for obtaining the least cost path between any two points using modern technologies such as GIS and remote sensing. Different data sources were collected to achieve optimal route location such as satellite images, soil map and minerals map. Other datasets were created as land use from classification of Landsat images and slope map from a Digital Elevation Model. All datasets are combined together in one geodatabase to allow integration with GIS analysis. In this paper, The Analytic Hierarchy Process (AHP) was used to derive the weights for five criteria, Slope, Minerals, Land use, Streams and Soil, in the development of pattern to obtain an optimal road. AHP is a resolution to making proceeding for establish advantage in many standards to decisions making to assess the relative weight of multiple criteria in an intuitive manner. Three paths from the estimates were appreciated which optimal and differed from the original way suggest for the project. It is concluded that GIS with integration of different sources of data and remote sensing and analysis using AHP technique should be adopted as a tool for future projects.
