I am a newbie to GIS platforms so maybe whatever I am asking is very simple or obvious. I have read documentation/tutorials and as a last resort I am posting here, so any help is appreciated. I am not asking for code per se just point me to the right direction.
I am trying to create an Indoor Map application, I have installed PostGIS and pgRouting on the server. Now, I am not sure what is the easy way to add nodes and ways to the database because in every tutorial/documentation that I came across, people are using OSM data. For me, there is no OSM data. Can somebody explain how can we insert node & ways to database so that pgRouting can work.
