I have been working on a project for indoor navigation.
I made the floorplan of the building and road-map for routing purposes as shp files (using JOSM, making GeoJSON and then converting to shp file using http://www.mapshaper.org/)
Then using POST GIS ShapeFile Loader (of pgAdmin III) I imported road-map(route.shp) to the database.
In QGIS, i was able to use the shortest path plugin to do the routing
////////////////////////////////////////////////////////////////////////////////////////// The following are screen shots of route
The following are screen shots of route_vertices_pgr
When I tried to use the pgrouting plugin of QGIS , I got the below error
What am I doing wrong?
