Cost analysis over flight line and ground line alignments of highway—using remote sensing technique

Abstract

Development of highway alignment demands the planner to conduct map study, preliminary, reconnaissance and direct surveys. This takes much time and energy in preparing final drawings. Remote sensing acts as a very powerful tool to finalise the final alignment within less time and energy. The data-like soil type, landuse, terrain and topographical features are collected from imagery and census data were used in this analysis to identify the flight line alignment. In this work techniques like trip distribution model and trip polygon method are approached in finalising flight line alignment. Apart from this the ground line alignment is developed with the above data and the difference in cost is estimated.
