Compute a bounding box around a point

Returns a bounding box vector suitable for the bbox argument of ncei_stations() and get_noaa_stations().

Usage

ncei_bbox(latitude, longitude, dist_km)

Arguments

latitude, longitude

Numeric. Target coordinates in decimal degrees. Latitude must be between -90 and 90; longitude between -180 and 180.

dist_km

Positive numeric. Half-width of the bounding box in kilometres.

Value

A numeric vector c(north, west, south, east).

Examples

# Bounding box 50 km around Konza Prairie
ncei_bbox(39.1, -96.6, 50)
#>     north      west     south      east 
#>  39.55045 -97.18044  38.64955 -96.01956
