I am trying to create a leaflet application. I want state shapes of Germany for a use case of the application. Is there a source where I can get all the boundary coordinates for the states. If not, is there a way to achieve the result without the coordinates.

Sample state coordinate for a the US state of Alabama looks like this.

var statesData = {
    "type": "FeatureCollection",
    "features": [{
        "type": "Feature",
        "id": "01",
        "properties": {
            "name": "munich",
            "density": 0
        },
        "geometry": {
            "type": "Polygon",
            "coordinates":  [

The website http://www.openstreetmaps.org contains all of this information, though you might have to figure out what boundaries you want exactly (some documentation here: http://wiki.openstreetmap.org/wiki/Key:border_type)

Two examples of borders:

UPDATE:

After I posted my answer I found a previous, more extensive answer to this question here

OLD Answer:

GADM provides maps of countries at three levels of detail. Go to the web site, click the download tab, then use the pull-down menu to select Germany. There are several formats for the data. I usually use the shape files that have three levels of detail. adm1 should have the states (Länder). adm2 will have greater detail at the district level.
