g_buffer {gdalraster}

Compute buffer of a WKT geometry

Description

g_buffer() builds a new geometry containing the buffer region around the geometry on which it is invoked. The buffer is a polygon containing the region within the buffer distance of the original geometry.

Usage

g_buffer(wkt, dist, quad_segs = 30)

Arguments

wkt

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

dist

Numeric buffer distance in units of the wkt geometry.

quad_segs

Integer number of segments used to define a 90 degree curve (quadrant of a circle). Large values result in large numbers of vertices in the resulting buffer geometry while small numbers reduce the accuracy of the result.

Value

Character string for an OGC WKT polygon.
