Shown below are the 3D model, aspect map, slope map and shaded relief model of the San Francisco Bay Area. In the 3D model, the white and blue denotes elevation above the water body and the brown area denotes the water body. I chose SF Bay Area because it consists of both land terrains and water bodies and I’m curious of what the area would look like in a 3D model. The combined information from the maps and model provided a wealth of information about the terrain in SF Bay Area. For example, it provides a clear picture on how the land terrain would look like on the ground. It also shows slope gradient and elevation, making it is perfect for terrain analysis.
