Feature/add route server UI editor

[bekirbostanci]

This PR adds a step-by-step guide for generating route graphs using the VDA LIF Editor, a web-based tool for creating maps in Nav2-compatible GeoJSON formats.

The documentation covers:

• Tool overview and usage
• Coordinate system setup
• Node and edge creation
• Exporting to ROS GeoJSON and LIF

Useful for anyone integrating VDA-compliant maps into ROS-based systems.

Looks great!

FYI @bekirbostanci I've tried using this recently and ran into an issue. This looks fine:

But that's not what's exported:

I can also see if this I export the LIF file and try to open it in a new tab, it also looks crumpled and to the wrong scale (my slam was at 0.02m resolution, the width/height are set correctly). I also see it created 2x edges that were half populated (had startid but no endid) and didn't need to exist at all - which took me quite awhile to figure out.

Hey @SteveMacenski
I see the problem, I will fix it today or tomorrow. Thanks for report.

[bekirbostanci]

Sorry about the bug and fixed now

[SteveMacenski]

Great! I’m curious what the issue was for my personal curiosity. I tried to check based on manual transcription of a few points and noticed the coordinates actually in the GUI were also crumbled even though they appeared correct.

[bekirbostanci]

It was entirely my mistake :) The problem was that the network-graph component wasn’t syncing properly with the layout conversion, which affected both the VDA5050 LIF format and ROS network format.

I’ve made some changes, and it should work correctly now. If you notice any other issues, please let me know.

[SteveMacenski]

Does that also explain the couple of half-created edges with a startid but no endid?

[bekirbostanci]

No, it doesn’t explain it. By the way, is there only one edge like that and always startid= 0? Because I see another issue: the first point is a connection but also an undefined point. This is reason why there is undefined endid. I am working on that right now.

[bekirbostanci]

This bug also fixed

[SteveMacenski]

Oooo nice! What was that one out of curiosity? I didn't see the undefined, it just only had a startid with no endid. I want to say it did have an ID of 0, but I don't recall with certainty. I didn't commit it to my project until after I removed it so the Route Server would load.

Great work by the way, minus these hiccups it was really easy to set up a room for a demo. I made a gif for ROSCon presentation next month

[bekirbostanci]

The cause of the second issue was that when creating a node, editor always connects to the last selected node. However, if no node was selected, it assigned an empty ID, which is why it returned undefined. In short, it was another overlooked case. Thanks again. I’ll be looking forward to ROSCon!
