Simple tool to see live changes in OSM.
LiveMapViewer ( http://gpsmid.sourceforge.net/misc/LiveEditMapViewerJ.jar ) is a tool to see live changes based on Planet.osm diff.
The tool is developed by User:Amm.
The colored dots have the following meaning:
blue = new node
green = modified node
red = deleted node
Once the tool was started, it downloads the latest diffs (once a minute) and draws the created / modified / deleted nodes on a slippy map. You can navigate in the slippy map in the same way as in the slippy map on the OpenStreetMap.org homepage.
Shift-Clicking on a node will open up more information about the node in your browser (shows the OSM-browse page for the node).
The way LiveEditMapViewer is written, it is quite resource intensive, so watching the whole world for a long time might not be possible. You can however specify a bounding box to limit the area you want to watch. This can be done by specifying bounding box parameters when starting LiveEditMapViewer. E.g. "java -jar LiveEditMapViewerJ.jar -12.0 35.0 45.00 72.00" would watch changes done in Europe. Or, if you want to watch to whole world, just occasionally restart.
Note: During the redaction period as part of the changes for the new licence change, the URL for the minute diffs have moved. You should use this binary (iveEditMapViewerJ-redaction.jar) in the meantime:
LiveEditMapViewerJ is open source and the source code can be found in the OSM SVN repository at (https://trac.openstreetmap.org/browser/applications/utils/LiveEditMapViewer).
