TOPICS COVERED IN THIS PRESENTATIONDevelopment of the data modelCreation of the network datasetGenerating routes using pgRoutingRouting in polygon layers (an alternative approach)
DEVELOPMENT OF THE DATA MODEL
CREATION OF THE NETWORK DATASETFloorplans (CAD to SHP)Digitise links [and rooms] - QGISUnique startpoint/endpoint - GDAL commandsBuild network (source/target/cost)
GENERATING ROUTES USING PGROUTINGQgis2threejs plugin
Demo
ROUTING IN POLYGON LAYERSGRASS GIS (to rasterise vector polygon)
r.cost - Creates a raster map showing the cumulativecost of moving between different geographic locations onan input raster map whose cell category values representcostr.drain - Traces a flow through a cost surface on araster map
