Takes a bounding box and calculates the minimum square bounding box that would contain the input.
-
bbox
BBox extent in [west, south, east, north] order
const bbox = [-20, -20, -15, 0];
const squared = turf.square(bbox);
//addToMap
const addToMap = [turf.bboxPolygon(bbox), turf.bboxPolygon(squared)]
Returns BBox a square surrounding bbox
