Is there any way to convert data from a PostgreSQL noded table into an osm2po graph? this library is able to read pbf data and generate a graph from osm data but If I want to update roads data it is not possible. I can update a PostgreSQL database which contains osm data but have no idea if it is possible to deploy them into an osm2po graph?
Answer
I'm sorry it's not. osm2po is a chain of many conversion steps. The generated postgres table is only one of many. However, technically osm2po is prepared for custom sources. But this has to be implemented per use case and input format individually.
