osmsource_osmosis: Osmosis OSM data source

Description

Planet dumps as OSM data source through the osmosis command line Java application.

Usage

osmsource_osmosis(file, osmosis = "osmosis")

Arguments

file

The file name (and path) of the planet dump

osmosis

The path to the osmosis application

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);

Details

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.

Examples

## Not run: 
#     ## Download and extract a planet file:
#     download.file("http://osmar.r-forge.r-project.org/",
#                   "muenchen.osm.gz")
#     system("gzip -d muenchen.osm.gz")
# 
#     ## Define osmosis source; note that we assume that
#     ## osmosis is in our path environment variable (if
#     ## not, set osmosis argument to the executable):
#     src <- osmsource_osmosis(file = "muenchen.osm")
# 
#     ## Get the center of Munich:
#     muc_bbox <- center_bbox(11.575278, 48.137222,
#                             3000, 3000)
#     muc <- get_osm(muc_bbox, src)
#     muc
#   ## End(Not run)
