bbox_from_wkt {gdalraster}

Get the bounding box of a geometry specified in OGC WKT format

Description

bbox_from_wkt() returns the bounding box of a WKT 2D geometry (e.g., LINE, POLYGON, MULTIPOLYGON).

Usage

bbox_from_wkt(wkt, extend_x = 0, extend_y = 0)

Arguments

wkt

Character. OGC WKT string for a simple feature 2D geometry.

extend_x

Numeric scalar. Distance to extend the output bounding box in both directions along the x-axis (results in xmin = bbox[1] - extend_x, xmax = bbox[3] + extend_x).

extend_y

Numeric scalar. Distance to extend the output bounding box in both directions along the y-axis (results in ymin = bbox[2] - extend_y, ymax = bbox[4] + extend_y).

Value

Numeric vector of length four containing the xmin, ymin, xmax, ymax of the geometry specified by wkt (possibly extended by values in extend_x, extend_y).
