3 3D GIS Viewing geospatial data in 3D leads to new insights 2D 3D Sometimes you need to edit your data in 3D 2D 3D Some problems can only be solved in 3D 3D 3D We live in a 3D world, so model and present your data in 3D

4 ArcGIS A complete system for 3D GIS Visualize Manage Share Analyze Your City Data in 3D

5 Virtual City Template - Philadelphia Visualization ingredients optimization City Management creation / storage updates 3D City Analyses Visibility Shadow/glare effects 3D routing Sharing of Virtual City

6 Visualize Virtual Philadelphia ingredients Visualize Manage Analyze Share Topographic maps Aerial photographs High resolution terrain Visual Impact Before After Photo realistic 3D buildings Providing 3D insight into your information

7 Ingredients Topographic basemap Visualize Manage Analyze Share Streets Shaded Relief Vegetation Labels Buildings Map Template Resource Center Topographic basemap

8 Ingredients Imagery Visualize Manage Analyze Share ArcGIS Server Image Extension Imagery from ArcGIS Online Resource Center

9 Ingredients Elevation Visualize Manage Analyze Share Elevation Globes from ArcGIS.com

10 Ingredients Buildings Visualize Manage Analyze Share Extruded Buildings Textured Buildings Sources of textured buildings - Pictometry Building your own multipatch buildings

12 3D Datatypes in the Geodatabase Vector feature classes with X,Y,Z geometry 3D Points 3D Geometric primitives (spheres, pyramids, ) 3D Models: Street furniture, etc. 3D Character Markers, or Billboarded Markers 3D Lines 3D Geometric primitives (ribbons, tubes. ) 3D Texture Line Symbols 3D Polygons 3D Texture Fill Symbols Elevation grid rasters (DTM/DEM) Terrains (TIN, Point cloud, surface) Multipatch (volumetric bodies)

13 Introducing Terrains Massive point datasets with a multi-resolution, on-the-fly TIN For modelling 3D surfaces Measurements stored as feature classes within a feature dataset User defined pyramid levels for different resolutions & tolerances 3D Analyst extension required to define & edit terrains No license needed to view A

14 Characteristics of Terrains Terrains quickly deploy & visualize TIN based surfaces at multiple scales Derived from a set of feature classes with features that contain z-values Different pyramid level TINs can be defined Breaklines & polygons can be added to further delineate surface CdnRockies CdnRockies_Terrain Points Breaklines LakeBoundaries Pyramid TIN surfaces

15 Terrains in ArcGIS Assist visualization & analysis of multi-resolution data Can integrate with other geospatial information Multi-user access in a versioned GDB ArcMap ArcGlobe Displays as a TIN Layer Displays as an Elevation Layer

16 Introducing Multipatch A geodatabase feature type for 3D objects. Collection of triangle strips, triangle fans, triangles, and rings Allow storage of texture image, colour, transparency, and lighting vector information within the geometry

17 Triangle Strip A continuous, linked strip of 3D triangles where every vertex after the first two completes a new triangle

18 Triangle Fan A continuous fan of 3D triangles where the first point defines the apex that all triangles share

19 Triangle A collection of 3D triangles where each consecutive triplet of vertices defines a new triangle

20 Ring A geometric element from which polygons are constructed, defined by an area bounded by one closed sequence of connected segments

21 Collections can be complex A single composite multipatch can contain multiple patches of varying types

22 Textures can be applied Two rings and one triangle strip Different textures for roof, floor and walls

24 Data Collection Elevation Types of Data Imagery Subsurface Models and Multipatches Topographic (2 or 3D) Additional Features Across Scales Local Regional Global

25 Data Conversion: Import 3D Files Input Formats COLLADA SketchUp OpenFlight 3ds Max GeoVRML These formats can store geographic location

26 Data Conversion: Data Interoperability Extension Can convert a large variety of formats to the Geodatabase CityGML IFC Can control the type of data that is produced

27 Data Conversion: Layer 3D to Feature Class 3D Symbology Extrusion Settings Texture Downsampling
