Читать книгу Designing Geodatabases for Transportation - J. Allison Butler - Страница 40

There are other geodatabase classes with specialized applications that will be discussed in later chapters. These classes include:

• Junction feature classes and edge feature classes that form a geometric network

• Turn feature classes that allow you to modify the default behavior of a transportation network

Because an understanding of these classes is necessary to use them in a data model, they are omitted from this “sidebar” chapter. Geometric networks are discussed in chapter 5. Transportation networks supported by the ArcGIS Network Analyst extension are covered in chapter 13.
