The path to the osmosis application
Osmosis is a command line Java application for processing OSM data. It allows, among other things, to extract data inside a bounding box or polygon from so called planet dumps. The usage of this source requires an installed osmosis; see http://wiki.openstreetmap.org/wiki/Osmosis.
center_bbox to retrieve:
all nodes that are inside a given bounding box and any relations that reference them;
all ways that reference at least one node that is inside a given bounding box, any relations that reference them [the ways], and any nodes outside the bounding box that the ways may reference;
all relations that reference one of the nodes or ways included due to the above rules (does not apply recursively);
