s2_bounds_cap function

Compute feature-wise and aggregate bounds

s2_bounds_rect() returns a bounding latitude-longitude rectangle that contains the region; s2_bounds_cap() returns a bounding circle represented by a centre point (lat, lng) and an angle. The bound may not be tight for points, polylines and geometry collections. The rectangle returned may depend on the order of points or polylines. lng_lo values larger than lng_hi indicate regions that span the antimeridian, see the Fiji example.

s2_bounds_cap(x)

s2_bounds_rect(x)

Arguments

• x: An s2_geography() vector.

Returns

Both functions return a data.frame:

• s2_bounds_rect(): Columns minlng, minlat, maxlng, maxlat (degrees)
• s2_bounds_cap(): Columns lng, lat, angle (degrees)

Examples

s2_bounds_cap(s2_data_countries("Antarctica"))
s2_bounds_cap(s2_data_countries("Netherlands"))
s2_bounds_cap(s2_data_countries("Fiji"))

s2_bounds_rect(s2_data_countries("Antarctica"))
s2_bounds_rect(s2_data_countries("Netherlands"))
s2_bounds_rect(s2_data_countries("Fiji"))
