Contour lines generated using Aerial Drone Survey

What are Contour lines? Contour lines are generated by connecting all the points of similar elevation together. These lines are drawn on a plan of a particular terrain to understand the nature of surface, identify cut fill volume, study water flow characteristics, estimate valley depth and steepness. Contour lines form a smooth curve of same elevation points. Contour lines are also called as isohypse,  isoline, isopleth, or isarithm. Contour maps are generated of Hill Ranges, Valleys, … Continue reading Contour lines generated using Aerial Drone Survey →
