Contourmerge Plugin

The contourmerge plugin helps you to align the contours of areas in JOSM.

Usage

Step 1 - Select the "cut-nodes":

• Enable mode, you will need to select (at least) two points for every area; but not on ways - there no requirement in minimal node count for ways that are not areas;
• Use left mouse click to select point (icon: standard icon add node will appear); use left mouse click to deselect a point (icon with cross will indicate selected point);
• After all 2+ points selected, you can pick one of 2+ parts as source geometry to move. Hover a mouse over one part and cursor will be changed to (cursor: move with 4 arrows);

Step 2 - Drag the source contour:

• After you started to drag source geometry, you have options in target geometry. Your source geometry will change it's shape to a target geometry shape after mouse hover and shortcut icon will be displayed;

Step 3 - make adjustments and continue editing as usual:

• Contours will be merged. But if a source geometry had only one segment left, it will be completely collapsed;
• You can repeat steps 2-3 as many times as you want until tool will disabled or there nothing left to merge

Usage on areas

• Regular usage:
  
  
  
  
• Complete collapse of the source geometry:
  
  

Usage with ways

Notes on source:

• tags on a way will be kept
• tags on nodes will be discarded
• geometry will be replaced

Notes on target:

• nothing is changed
• No cut points selected (because both objects are ways, not area):
  
  
  
  
• multiple source geometries:
