Question

Give an account of topographic analysis in GIS.

Answer 1

Surfaces can be represented using contour or iso-lines, arrays of points, TINs, and rasters; however, most surface analysis in GIS is done on raster or TIN data. Contours are sets of lines of equal value across a surface. They are frequently created to represent surfaces on a map.
