Details

#' @section Supported request elements:

Bounding box:

Use corner_bbox or 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);

Basic request elements:

Use node, way, relation to retrieve an element by its ID.

Use full = TRUE as additional argument to the get_osm function. This means that all members of the specified elements are retrieved as well:

• For a way, it will return the way specified plus all nodes referenced by the way.

• For a relation, it will return: (1) the relation itself; (2) all nodes, ways, and relations that are members of the relation; and (3) all nodes used by ways from the previous step.
