“…Modern cartographic [2] and GIS software packages [3] were mostly used but they lack in quickly and easily creating customized contour lines. GIS and image-editing software [4] is a time-consuming and multi-step process. Various modern tools like GMT (Generic Mapping Tools) [5], LASTools [6], NCAR Graphics Software Package [7] were developed for contour formation.…”

3D modelling of land survey is necessary for various geographical applications like surveying, levelling and geographic analysis. Traditional method for contouring using dumpy level is a measurement of altitude with reference of a reference point that requires manual measurement and provides accuracy of 0.17 m. This method is time consuming to perform the manual process for more number of points of survey. Manual errors may be introduced in this method. The quick altitude measurement and 2D & 3D contour formation method is required to be developed for accurate analysis. A novel method for altitude measurement is proposed using controlled drone that scans the specified area in predefined manner and measures the corresponding altitudes of drone from the earth surface points to calculate the altitudes of every earth surface point with reference to the initial reference point. The altitude data of the specified earth surface points are send to cloud for storage and computing purpose. Cloud computing is performed for 2D & 3D contour formation using MATLAB cloud computing functions. Final information is displayed on web site and can be accessed remotely from anywhere through proper authentication.
