## osmdata class def

### Description

Imports OpenStreetMap (OSM) data into R as either 'sf' or 'sp' 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_sf: Return OSM data in sf format

- osmdata_sp: Return OSM data in sp format

- osmdata_xml: Return OSM data in XML 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
