Abstract

Traditional Photogrammetric techniques involve use of high-resolution sensors mounted on the aircraft for data acquisition supported by ground control points. Flying operations and high-resolution topo surveys are traditionally associated with huge capital and logistics cost. In a developing country like India, it becomes more difficult to spend huge money on flying and surveying activities. Moreover, the rapid changes in the Indian context makes it mandatory to update the maps and database on frequent basis.

Our study aims to outline a revolutionary, low cost, user-friendly photogrammetric technique for producing high-resolution Orthophoto for the road corridor. For the study Canon EOS 70D and Canon EOS 80D, 20.2 megapixels with APS-C CMOS sensor are mounted on the top of car with a clear field of view to acquire data across the road corridor. Ground control points are measured as RTK solution. Image acquisition is done in parallel with ground control points across the study area. This paper will present the outline of the methods used to acquire the imagery, Ground control points and it's processing to create the Digital Terrain Model (DTM) and Orthophoto. Our results and experiences indicate that the technique is an inexpensive, effective and flexible approach to the traditional photogrammetry.
