Sam's Transport Bits
by samuelh2005
Sam's Transport Bits lets players design road networks in the world, place road nodes and link them, then export the network as an OSM XML file for rendering with outside map tools.
What it does
Road nodes are placed on the ground where roads should run. A player links nodes by interacting with a Road Connector on one node and then on the next, and finishes a link when the route is complete. Sneaking while interacting with a node shows its information. The export command writes the whole road network to an OSM XML file, which can then be opened in any OpenStreetMap tool of the player's choice.
The mod is open source under the GNU Affero General Public License v3.0 only, so the source code, issue tracker and wiki are all public. It runs on Fabric and Forge, with files for 1.20.1, 1.20.2, 1.20.3, 1.20.4, 1.20.5, 1.20.6, 1.21, 1.21.1, 1.21.2, 1.21.3 and 1.21.4. Client and server both need it. The author originally made it for personal use, and further additions are on the development list.
Key features
Road node placement
Road nodes are placed directly on the ground, forming the points that a road network is built from.
Node linking with connectors
A Road Connector links one node to another, and each link is finished by interacting with the second node.
Node information view
Sneaking while interacting with a road node opens its information, showing the data stored for that point.
OSM XML export
A command exports the road network as an OSM XML file, so outside OpenStreetMap tools can render it.

Use cases
Designing a road map in a world
A player can lay out a road network in a world by placing nodes, linking them and checking each node's data before exporting.
Rendering roads with OSM tools
The exported OSM XML file can be opened in favourite OpenStreetMap tools to produce maps of the network.
Who it’s for: Players who build roads and transport networks in their worlds, and server owners who want road layouts exported for outside map rendering.
