Comparison of D16 (a) and D8 (b) in term of edge reliability aspect
edge result produced by D8 algorithm where it clearly shows that some of them
point blindly toward no data provided by raster or pixel.
4.2 Topographic Map Result (3D View)
Figure
16
shows that D16 has more capability to model flow divergence and
produce reliable result compared to D8 result in Fig.
17
. When visualising and
inspecting each corner of the 3D model for both results, it clearly showed that D16
produce better reliability of flow divergence either in ridge area or at stream
