3. Chronology Statewide Orthophoto Program 1974. GIS Layer Development 1983. Result: 2D Map containing - Zoning - Zoning - Soils - Soils - Parcels - Parcels - Elevation - Elevation - Infrastructure - Infrastructure Town Center shops with Camels Hump mountain in the background.

4. Mission Making, Taking the right growth decisions. Issues of aesthetics shall extend to: - Building Design - Building Design - Continuity with adjacent Structures - Continuity with adjacent Structures - Views of the surrounding - Views of the surrounding Landscape Landscape Area of particular Interest: ‘The New Town Center’

5. The Town Center Location: - Accessed by two major state highways. - Accessed by two major state highways. - Wide panoramic Views of the mountain and valley. - Wide panoramic Views of the mountain and valley. Land Use: - Residential & Commercial Uses. - Residential & Commercial Uses. - Buildings up to 3 Stories. - Buildings up to 3 Stories.

6. Project’s Problematic Prediction: - How can the impact be predicted? - How can the impact be predicted? - What future uses shall be recommended? - What future uses shall be recommended? - How will the current building densities affect the area in the future? - How will the current building densities affect the area in the future? Grocery store with proposed brick buildings in the background.

7. Finding Solutions Given: 2D Map Missing: A reliable Method to view the area in 3-dimensional form to evaluate the impact of 3-dimensional form to evaluate the impact of proposed three-, and four-story structures proposed three-, and four-story structures Solution: Arc GIS 9 3D Analyst - Simulation Capabilities - Simulation Capabilities - Rendering Capabilities - Rendering Capabilities Essex Cinema and the mountains to the southeast.

8. Methodology Data Collection (3dimensional). Assimilation into Arc GIS Desktop. (Orthophoto, terrain Data, Parcels, Zoning & CAD dwgs.). (Orthophoto, terrain Data, Parcels, Zoning & CAD dwgs.). Construction of the Scene using the Library of 3D Symbols and custom 3D Symbols. Trees and Vegetation Elements were added using Arc GIS 9 3D analyst.

9. Goal Representation of Town Center area after 20 to 30 years to evaluate how tree growth might affect views of the mountains. Bionatics offered REALnat that simulates Tree Growth according to mathematical Seeds. Bionatics offered REALnat that simulates Tree Growth according to mathematical Seeds. “REALnat made extensive Tree Creation a matter of just a few Hours” “REALnat made extensive Tree Creation a matter of just a few Hours”

10. January 2004 Green mountain Geographics (GMGG). First public presentation of the Town Center. First public presentation of the Town Center. “It might be too early to proclaim the end of the artist rendering” Smith says, “but the impact of GIS, using the virtual 3D environments of ArcGIS, will become a powerful tool. 3D simulation is here to stay.” “It might be too early to proclaim the end of the artist rendering” Smith says, “but the impact of GIS, using the virtual 3D environments of ArcGIS, will become a powerful tool. 3D simulation is here to stay.”
