Visualizing and Navigating Building Interiors

Agenda

1. Building Interior Scale / LoD

2. CAD GIS

3. Creating Indoor Transportation Networks

4. Publishing Campus Layers

5. 3D Campus Viewer Web App

Level of Detail 4 (LoD4)

• LoD range (0-4) adopted from CityGML*

- LoD0 = 2D polygon

- LoD1 = + extrusion

- LoD2 = + roof form

- LoD3 = + architectural detail

- LoD4 = + interior features (walls, floors, doors, furnishings)

*May be textured or un-textured at each LoD

Data Loading: CAD GIS

• Load CAD floor plans into a GIS schema

- Populates Local Government Information Model

- Python tool + configuration file (.xlsm)

- Supports National CAD Standard / AIA CAD Layer Guidelines

- 3D-enables floor plan data for 2D or 3D uses

Indoor Transportation Networks

Goals

• Meet user demand for navigation insides buildings

• Streamline the network creation process

• Support common Network Analysis tasks

Network Creation: Manual

Network Creation: Automated

1. Create rotated lattice

2. Clip to floor

3. Add walls

4. Calculate wall

distance

5. Add spaces

6. Add path hierarchy

and spaces

7. Calculate floor paths

8. Repeat for all floors

9. Add transitions

10. Deploy Network

Esri Campus Network

Publishing Campus Layers

Foundational Layers

- Routing Service

- Campus Exterior

- Tiled Campus Basemap

- 3D Trees

- Building Façades (textured)

- Campus Interior

- Spaces, Walls, Doors (by floor)

- Building Facades (wireframe)

- Space Points

- Operational Data

- Evacuation Plan

Viewer Web App

Campus Routing App for Mobile

• Companion Mobile App

• Written using Xamarin

- Beta of the ArcGIS API for Xamarin

- UI uses Xamarin forms (not platform-specific)

• On-device transportation network & GDB

- Route preference

- Floor-by-floor route display
