Exploring Elevation Models

   In this lab, I explored two types of elevation data models, the Triangulated Irregular Network (TIN) and the Digital Elevation Model (DEM). Both are useful for representing terrain, but they work in different ways. The TIN uses triangles to capture specific elevation points, giving it more accuracy in areas with steep slopes or sharp elevation changes. On the other hand, the DEM represents the terrain as a grid, which smooths the surface, making it more generalized.

One of the key things I noticed was how the contour lines differed between the two models. The TIN provided sharper contours in areas with more dramatic elevation changes, while the DEM's contours were smoother, especially in flatter regions. This comparison helped me understand when to use each model: TIN for more detailed terrain analysis and DEM for a broader, more averaged view.
