Tool for analyzing created graph

[LWeber]

As of playing around with complex turn restrictions I wanted to know if there is a functionality to view a graph in a table structure as referenced in the technical.md. In the graph-cache it’s all binary.

Background:
I want to create a server based on graphhopper/test_simple_turncosts.osm.xml but somehow I can’t access all nodes (Cannot find point 1: 0.0,-1.0) and want to dig deeper.

Try the BaseGraph#debugPrint method I just added, or if it does not do what you need write some code that does something similar.

but somehow I can’t access all nodes (Cannot find point 1: 0.0,-1.0) and want to dig deeper.

What were you trying to do?

[LWeber]

Thanks for adding this functionality! That was realy quick.

I need to work myself into turn restrictions and wanted to understand the test_simple_turncosts example.

So my graph looks like this:

and it throws an error when routing via new GHRequest(0, 0, 0, -1) despite the node seems to be there

Well these coordinates probably are too unrealistic. I guess they work for the turn cost example, but otherwise they are way too far apart. Maybe just divide all the lat/lon values by a factor of 100 or so and see if that makes a difference?

I just saw in graphhopper/RoutingAlgorithmWithOSMTest.java that you are using 0.49 instead of 0.5.

So the call works with new GHRequest(0, 0, 0, -0.99)

Thank you anyway for the debugPrint!
