as_proj_area: Summarise a geographic area
In paleolimbot/rlibproj: Generic Coordinate Transformation Library ('PROJ') R API
Description
Usage
Arguments
Value
Examples
Description
The concept of an "area" in PROJ means a geographic one
that can span the antimeridian. This function uses some
heuristics to find the minimum longitude span of the
input (provided that the longitude span is less than
180 degrees). The wk::wk_crs() of the input is
considered and the appropriate transform to WGS84
is applied.
Usage
1
as_proj_area(handleable)
Arguments
handleable
A geometry vector (e.g., wkb(), wkt(), xy(),
rct(), or sf::st_sfc()) for which wk_handle() is defined.
Value
c(west, south, east, north) in WGS84
Examples
1
2
as_proj_area(wk::rct(-1, -1, 1, 1))
as_proj_area(wk::rct(-179, 179, 1, 1))
