osmdata: osmdata class def

In osmdata: Import 'OpenStreetMap' Data as Simple Features or Spatial Objects

osmdata class def

Description

Imports OpenStreetMap (OSM) data into R as 'sf', 'SC', 'sp', 'data.frame' or 'xml_document' objects. OSM data are extracted from the overpass API and processed with very fast C++ routines for return to R. The package enables simple overpass queries to be constructed without the user necessarily understanding the syntax of the overpass query language, while retaining the ability to handle arbitrarily complex queries. Functions are also provided to enable recursive searching between different kinds of OSM data (for example, to find all lines which intersect a given point).

Usage

osmdata(
  bbox = NULL,
  overpass_call = NULL,
  meta = NULL,
  osm_points = NULL,
  osm_lines = NULL,
  osm_polygons = NULL,
  osm_multilines = NULL,
  osm_multipolygons = NULL
)

Arguments

bbox	bounding box
overpass_call	overpass_call
meta	metadata of overpass query, including timestamps and version numbers
osm_points	OSM nodes as sf Simple Features Collection of points or sp SpatialPointsDataFrame
osm_lines	OSM ways sf Simple Features Collection of linestrings or sp SpatialLinesDataFrame
osm_polygons	OSM ways as sf Simple Features Collection of polygons or sp SpatialPolygonsDataFrame
osm_multilines	OSM relations as sf Simple Features Collection of multilinestrings or sp SpatialLinesDataFrame
osm_multipolygons	OSM relations as sf Simple Features Collection of multipolygons or sp SpatialPolygonsDataFrame

Functions to Prepare Queries

• getbb: Get bounding box for a given place name

• bbox_to_string: Convert a named matrix or a named vector (or an unnamed vector) return a string

• overpass_status: Retrieve status of the overpass API

• opq: Build an overpass query

• add_osm_feature: Add a feature to an overpass query

• opq_string: Convert an osmdata query to overpass API string

Functions to Get Additional OSM Information

• available_features: List recognised features in OSM

• available_tags: List tags associated with a feature

Functions to Extract OSM Data

• osmdata_data_frame: Return OSM data in data.frame format

• osmdata_sc: Return OSM data in silicate format

• osmdata_sf: Return OSM data in sf format

• osmdata_sp: Return OSM data in sp format

• osmdata_xml: Return OSM data in xml2 format

Functions to Search Data

• osm_points: Extract all osm_points objects

• osm_lines: Extract all osm_lines objects

• osm_polygons: Extract all osm_polygons objects

• osm_multilines: Extract all osm_multilines objects

• osm_multipolygons: Extract all osm_multipolygons objects

Note

Class constructor should never be used directly, and is only exported to provide access to the print method
