Editing an Exisiting Building

Help and support

While others have given you examples of how to get this done in ID…

In JOSM, this really is just a simple Alt+X after you install the helpful “UtilsPlugin2” JOSM plugin!

See an explanation+GIF of it in action in:

How to Split a Building in JOSM

0. Press A to get into “Draw” mode.

  • Or Mode > Draw.

1. Left-Click on one edge/node of the building.

2. Move the mouse and Left-Click on other edge/node of the building.

3. Press Alt+X.

  • Or More Tools > Split Object.

Done. :slight_smile:

And repeat 1–3 as many times as needed.

(To get this set up in JOSM, see the 2 tutorials I posted below.)

Side Note: I first began using it after manually splitting/“redrawing” many long rectangles of townhouses (or duplexes) into their individual houses.

(And this method really is so much better/faster than that current slow/clunky ID method.)

Now, I even have my extra mouse button set to Alt+X, so all I have to do is:

  • Draw line.
  • Click side-mouse button.

So I can split apart buildings as fast as I can do 3 clicks! :slight_smile:

How to install UtilsPlugin2 in JOSM

1. Edit > Preferences

2. Go to the “Plugins” tab.

3. Type utils into the search box.

4. Check the box ON next to utilsplugin2.

  • (As of today, it’s version 36362.)

5. Press OK button.

Now, close out of JOSM and reopen it from scratch.

Note: In order to more easily edit/open the location in JOSM, I also set up “Remote Control”.

This lets you easily just:

  • Visit the location on OSM.org.
    • For example, clicking on your forum link in Post #1.
  • You see that Green “Edit” button up top?
    • Click on the little dropdown next to it.
    • Press “Edit with Remote Control (JOSM, Potlatch, Merkaartor)”.

Now it’ll pop open that location in JOSM. You can then:

  • Do your edits in JOSM
  • Push the button to upload

and it’ll send all your changes back to OSM. :slight_smile:

How to set up “Remote Control” in JOSM

1. Edit > Preferences

2. Go to “Remote Control” tab.

3. Check the box ON for “Enable remote control”.

Then restart JOSM.

Now, all you have to do is:

  • Have JOSM open when you push that “Edit with Remote Control” green-button-dropdown

and it’ll automatically transfer the info to JOSM and load up that spot of the map.

Happy mapping! :slight_smile:
