Get the bounding box

Description

Returns the bottom left and top right corners of the box that contains a mapzen object (mz_geo_list, mz_isochrone_list, or mapzen_vector_tiles). In the case of mz_rect, creates such a box from the specified coordinates. The returned value can be used directly as the boundary.rect parameter for search functions, as well as converted to x, y, zoom coordinates to use with mz_vector_tiles.

Usage

mz_bbox(geo)

## S3 method for class 'mapzen_geo_list'
