Convert osmapiR objects to sf objects

Usage

st_as_sf.osmapi_map_notes(x, ...)

st_as_sf.osmapi_changesets(x, ...)

st_as_sf.osmapi_gps_track(x, format = c("line", "points"), ...)

st_as_sf.osmapi_gpx(x, format = c("lines", "points"), ...)

Arguments

x: an osmapiR object.
...: passed on to st_as_sf() from sf package.
format: Format of the output. If "line" (the default), return a sf object with one LINESTRING for each track. If "points", return a sf with the POINTs of the track as features. See below for details.

Value

Returns a sf object from sf package or a list of for osmapi_gpx and format = "points".

When x is a osmapi_gps_track or osmapi_gpx object and format = "line", the result will have XYZM dimensions for coordinates, elevation and time if available. In this format, time will loss the POSIXct type as only numeric For format = "points", the result will have XY dimensions and elevation and time will be independent columns if available.
