Reconstruction of contour lines during the digitization of contour maps to build a digital elevation model

Aroj Subedi; Pradip Ganesh; Sandip Mishra

Volume 6, Issue 4 , November 2020, Pages 239-250

  Contour map has contour lines that are significant in building a Digital Elevation Model (DEM). During the digitization and pre-processing of contour maps, the contour line intersects with each other or break apart resulting in broken contour segments. These broken segments impose a greater risk while ...  Read More
