    20. Source of 3rd Dimension Surfaces Raster data sources TIN data sources 2D feature classes (using attributes) 3D feature classes (using “internal” 3D coordinate values) 20 of 39 Data sources for 3D display and analysis

    21. Raster data sources Typical raster data sets from Spatial Analyst Create from any other supported data set Download DEM data Displayed in 3D based on cell values 21 of 39 Data sources for 3D display and analysis

    22. TIN data sources Vector-based data type Triangulated Irregular Network Composite of point, line, and polygon features Represents landscape surface as a set of triangular facets 22 of 39 Data sources for 3D display and analysis

    23. TIN data model Structure is complex or simple where necessary to model the landscape surface 23 of 39 Data sources for 3D display and analysis

    24. Display of TINs can be altered to show different landscape features 24 of 39 3D visualization: TIN legend editing

    25. All edges with nodes graduated color-elevation at nodes 25 of 39 3D visualization: TIN legend editing

    26. Display of TIN can be altered similar to feature symbology 26 of 39 3D visualization: TIN legend editing

    27. Elevation & aspect 27 of 39 3D visualization: TIN legend editing

    28. 3D Feature classes 2D feature classes have only X & Y coordinates as part of data structure 3D feature classes incorporate a Z coordinate as part of data structure Z-value can represent any numerical phenomenon Any 2D feature class can be converted to a 3D feature class Conversion based on a constant, attribute value, or surface model 28 of 39 Data sources for 3D display and analysis

    31. 3D surface draping Any 2D layer can be displayed draped over a surface based on common coordinate system registration E.g., streams roads digital orthophoto 31 of 39 3D visualization: Surface draping

    32. Draping with color ramping 32 of 39 3D visualization: Color hillshade mapping

    33. Draping, color ramping, and hillshading (surface looks realistic) 33 of 39 3D visualization: Color hillshade mapping
