Download from OSM

Keyboard shortcut: CTRL+SHIFT+D

Download data. Different type of data can be downloaded:

• osm data (nodes, segments, ways, ...), downloaded from the OpenStreetMap server.

• gps raw data, downloaded from the OpenStreetMap server.

The dialog has multiple tabs. The exact configuration of tabs may be dependent on plugins you have installed, but you will generally at least have:

• A bounding box tab where you can set the latitude/longitude bounds of the data to be downloaded, and also paste an URL from www.openstreetmap.org. To do this go to ​the map on the OpenStreetMap site, zoom in to the area you are interesrted in, move the mouse over the "view" tab, and copy the resulting URL. Then go to JOSM, and paste this URL into the "URL from www.openestreetmap.org" box. (In Windows to paste into the box, left click within the box, and then do CTRL+v)

• A bookmark tab where you can select from your predefined bookmarks, or make a new bookmark from the current bounding box.

• A world map where you can select an area for download using the mouse. The map is not detailed enough to actually select a very small area, but you can use it in conjunction with the other tabs - e.g. first select a bookmark, then zoom in on the world map and select an area slightly different from the bookmark area. The world map can be zoomed and panned just like the normal map display!

The bounding box tab will also display a warning if the selected area is too large for the server and will likely be answered with an error message. (You can try, though!)

When the download dialog is called up with data already loaded, all fields are set to the currently visible bounding box. Thus a common use scenario is to first load your GPS track from a GPX file, then zoom the view so that the portion you wish to work on is fully visible, and then call up the download dialog which will reflect the visible area.
