1 Local Government Scenes A collection of ArcGIS workflows that can be used to create and publish 3D scenes for your local government. Gert van Maren Esri Software Solutions

2 Local Government Scenes Solution Why is it important? More and more local governments want to start using 3D visualization in their day to day workflows to improve spatial understanding and communication e.g. with internal stakeholders and / or the public Lidar data courtesy of CERA and AAM Group ltd

3 Local Government Scenes Solution Why is it important? A big barrier to the adoption of 3D visualization is the lack of readily available 3D spatial content such as elevation, 3D buildings, 3D trees

4 Local Government Scenes Solution Why is it important? Local governments need a collection of workflows to create and publish 3D base scenes from their existing spatial data Lidar Building footprints

5 Local Government Scenes Solution A collection of ArcGIS workflows that can be leveraged by Esri customers and their stakeholders to: Create and Publish 3D local government scenes as web scenes on premise and ArcGIS Online Basic Scene Realistic Scene Schematic Scene

6 Esri s Offering

7 Basic Scene (LOD1) Workflow steps Create the Basic Scene - Elevation layer - World Topographic basemap - LOD1 buildings - Simple trees Publish Basic Scene to Portal - Building footprints - Lidar - Elevation - LOD1 Buildings - Schematic Trees Author the Basic Scene in the Web Scene Viewer Basic Local Government Scene

8 Basic Scene Web scene

9 Basic Scene Specifications Required: - Classified lidar (ground with first return only) - Building footprints (schema agnostic) LOD1 (Level of Detail) 3D scene - Attribute driven extrusion - Procedural representation - Automatic generation Usage: - Massing visualization - Conceptual planning

10 Schematic Scene (LOD2) Workflow steps Create the Schematic Scene - Elevation layer - World Topographic basemap - LOD2 buildings with floor indication - Simple trees - Building footprints - Lidar - Elevation - LOD2 Buildings - Schematic Trees Publish Schematic Scene to Portal Author the Schematic Scene in the Web Scene Viewer Schematic Local Government Scene

11 Schematic Scene ArcGIS Workflow ArcGIS Pro tasks - Publish Elevation layers** - Publish LOD2 Buildings - Roof form extraction - Quality Control - Refine roof forms - Publish 3D Trees Author the Web Scene - Add Layers - Configure Layers - Create Slides - Set Scene Properties

12 Attribute Driven Roof Forms Roof-Form Extraction Process Quality control Refine building roof form

13 Schematic Scene Web scene

14 Schematic Scene Specifications Required: - Classified lidar - ground with first return only - 3 feet or less point spacing - Building footprints (schema agnostic) LOD2 (Level of Detail) 3D scene - Attribute driven roof forms - Procedural representation - Semi-automatic generation Usage: - manual clean-up for complex roofs - in-depth city planning - supports zoning visualization, shadow, visual impact, and solar exposure.

15 Realistic Scene ** Workflow Create the Realistic Scene - Elevation layer - World imagery - LOD2 buildings with textures - 3 rd party LOD3 buildings - Realistic trees - Building footprints - Lidar - 3 rd party LOD3 buildings - Elevation - Textured LOD2 Buildings - LOD3 buildings - Realistic Trees Publish Realistic Scene to Portal Author the Realistic Scene in the Web Scene Viewer Realistic Local Government Scene

16 Local Government Scenes Solution Recap Esri supported solution to create and publish 3D local government scenes - FREE Input: Lidar (ground classified) and Building Footprints Output: 3D Scene with Elevation, Basemap, 3D Buildings, 3D Trees Quality depends on Lidar point density and Building footprint accuracy - > 3 feet point spacing LOD1 buildings - < 3 feet point spacing LOD2 buildings
