Tim Manner from Ordnance Survey explains how they created an indoor routable network using QGIS and pgRouting. In 3D using QGIS2ThreeJS to build an interactive map with live routing.

2. TOPICS COVERED IN THIS PRESENTATION
Development of the data model
Creation of the network dataset
Generating routes using pgRouting
Routing in polygon layers (an alternative approach)

3. DEVELOPMENT OF THE DATA MODEL

5. CREATION OF THE NETWORK DATASET
Floorplans (CAD to SHP)
Digitise links [and rooms] - QGIS
Unique startpoint/endpoint - GDAL commands
Build network (source/target/cost)

10. GENERATING ROUTES USING PGROUTING

12. ROUTING IN POLYGON LAYERS
GRASS GIS (to rasterise vector polygon)
r.cost - Creates a raster map showing the cumulative
cost of moving between different geographic locations on
an input raster map whose cell category values represent
cost
r.drain - Traces a flow through a cost surface on a
raster map
