Project Overview
Indoor mapping and Navigation for first responders
Survey of high risk facilities once a year as part of a preplanning process
Preplanning outputs often in report form and will annotate and even make their own maps
Preplanning is (currently) time consuming, inefficient and complex
LoD to be captured
Lack of automation
Difficult to identify changes between surveys

Activities
Convert 3D Indoor LiDAR point clouds and associated imagery to functional building and navigation models
Store and serve point Cloud, building and navigation models for visualization and navigation
Derive dynamic turn-by-turn indoor navigation instructions based on the navigation model
View and annotate Point Cloud data, imagery and building models, navigation routes and instructions in, thourgh and out of buildings

8. Public Safety Features Labelling
Identify Public Safety Features based on NAPSG symbology. Features prioritized by input collected from sponsor
Select indoor/generic elements
A symbol that represents Room, Classroom
A symbol that represents Room, Utility Room
A symbol that represents Safety Location, HVAC ?
A symbol that represents Safety Location, Fire Extinguisher ?
A symbol that represents Safety, Decontamination Shower
Map symbology to data element
E.g. Safety location --> point, curve, surface or solid
Classify new feature and attributes
Features: Decomposition shower
Classroom, utility room

9. Navigation Modeling Service
Requirements
Service converts CityGML 2.0 Public Safety ADE to OGC Indoor GML
Map schema from CityGML to Indoor GML
Set default values where none are available in source
Merge indoor context information such as occupants
Generate nodes and linkages to support navigation
Perform validation and provide error codes when valid output cannot be generated
Interface using REST, WFS-T
Possible interface using WPS
