View > History

Keyboard shortcut: Ctrl+H

Display history infomation about OSM nodes, ways or relations in the history browser.
For each selected object(s) a seperate window will open.

With the History Browser you can browse through the history of an object. On the left a list of object versions is displayed. Two versions (A and B) are marked with a dot. You can manually place both dots or click on a date or user name to place two dots at once. You can also use the up and down arrows on your keyboard to move the dots up and down.

The right part of the window is halved and the tags of the in the list selected versions (A and B) are displayed. If tags were added, they are highlighted in green, if tags were removed, they are highlighted in red and if tags were changed, they are highlighted in light red.

Basic information about a version

The History Browser displays basic information about each object version:

• the object id, the unique number of the object (displayed in the window title bar)
• the version id, the unique number the OSM server assigned to this object version (1, 2, 3,...)
• the date of creation
• the user who created this version. Click on the link to launch a browser with additional information about the user.
• the changeset id, i.e. the unique number of the changeset in which this object version was created. Click on the link to launch a browser with additional information about the changeset. Click on the Changeset Button to open the Changeset Manager Dialog.
• the number of comments of the changeset discussion (if availible) with this icon:
• the changeset comment (if availible)
• the changeset source tag (if availible)
• the changeset imagery_used tag (if availible)
• the object tags

Via a right click on a version in the list of object versions, you can:

• Lauch browser with information about the changeset
• Lauch browser with information about the user

Multiple perspectives

Depending on the object type which is selected, there is a different second tab on the right part of the window. The different tabs are axplained below. If something changed between version A and B it is highlighted in light red, if something was removed it is highlighted in red and if something was added it is highlighted in green.

If a node was selected, coordinates tab

The Coordinates tab displays the longitude and the latitude of the node and the distance of the coordinates of the two selected versions. Additionally version A is highlighted as a red circle and version B as a green circle on the map below.

If a way was selected, nodes tab

The Nodes tab displays all nodes of the way with their id. The arrow down or arrow up in the heading of the table indicates if the nodes are displayed from first to last or vice versa. This helps to easier inspect reverted ways. If you revert the direction of a way, not all the nodes are reordered in this view, but just the arrow switches and the nodes which are in reversed order get a yellow background. In the example image below you can see that in the last change of this way (which is by the way not yet uploaded in this case) the way was reversed, one node removed and two nodes added.

If a relation was selected, members tab

The Members tab displays all members of the relation with their id, an icon of their object type and (if set) their role.
