Question
**Exercise 3: Creating a TIN Network and Drawing Contours** **Objective:** Create a Triangulated Irregular Network (TIN) and draw contour lines based on the following topographic survey data at 50-foot increments. **Elevation Data Points:** - X700 - X800 - X850 - X1000 - X900 - X750 **Instructions:** 1. Collect the elevation points and mark their respective locations on a plot. 2. Connect the points to form triangles, ensuring that each triangle side is as short as possible—this is the essence of a TIN network. 3. Use the triangular mesh to interpolate and draw contour lines at intervals of 50 feet. 4. Start from the lowest elevation point (700 ft) and draw subsequent lines until you reach the highest elevation point (1000 ft). **Illustration Details:** In the provided diagram, the elevation points are distributed across the area and marked with an "X" followed by the respective elevation in feet. The values range from 700 to 1000 feet, allowing for multiple contour lines to be drawn at 750, 800, 850, 900, and 950 feet increments.
