Creating 3D features from 2D features
A 3D feature is a 2D feature that has elevation (height) values (z-values) stored in its geometry. When you are creating a new feature class in your geodatabase, you have from the first panel Geometry Properties: Coordinate include Z values. Used to store 3D data. In Chapter 1, Designing Geodatabase, you created feature classes that store only 2D features.
In this recipe, you will convert the existing simple features (2D) into 3D features using two methods:
Based on the height values from a raster surface
Based on the height values from the 2D feature's field attribute
Getting ready
In this recipe, you will work with the ArcScene desktop application. ArcScene documents are saved as .sxd files. Your scene document will contain:
A raster surface layer created in Chapter 9, Working with Spatial Analyst, in the Analyzing surfaces recipe
Two 2D feature classes:
PointElevationandBuildings
