In this project an attempt is made to combine the programming and algorithm techniques for solving the complex process of aligning the new transmission line corridor in an area considering all the cost factors. This automated system viz. ATLAS solves the routing problem between the source and destination points depending upon the various input layers like Land Use layer, Soil layer, Geology layer, Road Layer, Highway Layer, etc. The system gives the least cost route between the two points based on two algorithms, Dijkstra and A*(star).The program uses raster analysis for computing the least cost path over the entire region. The designed application is area-independent. A sample for an area of 25 km x 25 km of Madhya Pradesh, India has been used for testing the application.

Electricity plays a very important role in the development of any nation. In India, power is generated from hydro-electric plants, nuclear plants and thermal power plants. The power thus generated is fed to a national grid which runs through the entire length and breadth of our country. An alignment is required through which power can be transmitted from generating station to the national grid. Cost is a primary consideration in this alignment planning. The conventional methods of alignment are time consuming and also end up with higher cost of survey. Remote Sensing and GIS have proven to be effective tools for solving the problem of alignment. So in this project an effort has been made to make this process of transmission line alignment simpler and less time consuming, by automating the process of generating the alignment of the transmission line.
