A Gis Anchored Technique to Obtain Optimal Path through Minimal Alteration of Land Type

This paper presented a technique to organize the digitized map of a very large area, using a flat-file system (without using databases); depicting necessary and useful information regarding land usage of the area, which can also be viewed as a land-type-data bank, where all the necessary information regarding the type of the land, owner etc. are kept. While associating data with each individual region, a priority value is also incorporated, where a lower value of priority signifies, higher possibility of the land to be selected for acquisition. As per needs to acquire lands for the construction of new utility services such as railway tracks, roads etc., the technique, upon input the source and the destination location, suggests the most suitable path, in terms of optimal costs, which is dependent on the parameters like compensation needed to pay during land acquisition (compensation amount increases, for acquiring more fertile lands), the length of the path etc. The suggested optimal path is presented onto the map graphically assisting the engineers involved in the work for proper implementation and utilisation of the land.
