Section Five: Display a Scene with More Realistic Details
Introduction
As you can see, the extruded buildings in the previous section, are blocks with no details, just the elevation. In this section, you will learn how to present part of west campus with more details. To do so, you should remove some of the features from UP_BUILDINGS that overlap with the layer that has more detailed information. This new layer (UP_Roof_Segments), that you will add to the map, consists of roof segments with detailed elevation. This information has been extracted from LiDAR data. In other words, instead of treating buildings as a big, undifferentiated chunk, every change in shape or elevation in each building has been detected and a new layer that represents those change/segments have been created. In Module 4, we have explained the process of creating this layer in detail.
