Summary: How to insert important road and trail junctions into road plans.

Instructions:
When digitizing roads and trails, all significant junctions should be labelled with a "junction code". The junction code looks like "Jct 24". You generate the junction number from the second decimal place of the latitude and longitude. Eg: A junction at 50.0749,-126.1465 would be called Jct 74.

The Jct keyword causes GMap to display the junction as a little brown icon. These are very handy for discussion in road bulletins. Eg: Someone can look at the map and say "There's a new road at Jct 26. The junction labels are also very handy when having to fix up existing waypoints. It makes it easy to replace the waypoints between two junctions without having to pick through the lat-longs on a twisty road.

The junction labels are easy to get when using GMap to digitize: when you right click to edit the point, the lat-long you need is right there. So you label each junction as you go along.

For a more detailed discussion of junction codes see Junction Codes.

Junction Records
 In addition to putting junction codes into the waypoints, as of September 2016, you can insert important junctions into the road plan page. Not all junctions have a junction record, only important ones you want to refer to in numerous places. Eg: You send an email to another editor and you can ask him what he found out about the new fork that goes up from junction 74. Editors can insert junction records from the road plan page. They can be inserted by any editor.

The system generates the junction code automatically. They are sorted on the road plan according to bivouac "Area Codes" such that junctions in the same area appear next to one another. When you click on a junction code in a road plan, it brings up a junction page with links to GMap.
