Expand Spatial Bounding Box

Description

Expand an sf bounding box by an expansion factor

Usage

st_expand(bbox, ef)

Arguments

bbox

An sf bounding box. See sf::st_bbox.

ef

Expansion factor, must be positive and length 1, 2 or 4. If length(ef)==1 then the expansion factor is applied equally in all 4 directions. If length(ef)==2 then the first refers to the x coordinate and the second is associated with y coordinate expansion. If length(ef)==4 then then the first 2 refer to expansion to the west and east of the x coordinate, and the last to expand the y coordinate in the south and north direction respectively.
