1. 3D GIS So far, all data has had x, y coordinates –North-south and east-west 3D requires a z value –Elevation and/or depth Mt. Everest Wordpress.com

2. Elevation: Height of land Typically: –Elevation above “mean sea level” –By default, from the ellipsoid defined in the datum Can have a “vertical datum” –Typically local datums Shuttle Radar Telemetry Mission (SRTM) Jet Propulsion Labs

3. Bathymetry Depth below “mean sea level” Frank A. Palmer and Louise B.Crary, that collided and sank in Massachusetts Bay in 1902.

4. Crater Lake Bathymetry From over 2000 surveys Wikimedia.org

5. ArcScene – 3D Viewer

6. Start with a DEM

7. All Layers at 0 Elevation

9. 3D Settings Elevation From Features Elevation from surfaces

19. 3D points displayed in volume space DOE/OSU

23. Can also create animations See youtube http://www.youtube.com/watch?v=qzkBnC BpQAMhttp://www.youtube.com/watch?v=qzkBnC BpQAM –Artificial terrain fly through (not ArcScene) http://www.youtube.com/watch?v=nhXaSc aT87ohttp://www.youtube.com/watch?v=nhXaSc aT87o –With music in ArcScene (you can do better) Note: ArcScene is not a gaming engine!

24. Temporal Data Adding temporal data to visualizations: –Land use change over time (NLCD) Elevation and remotely sensed changes Esri has added some temporal features: –Date/Time attributes –ArcMap is still basically a 2D application More complex temporal analysis and visualizations require special software
