g_buffer {gdalraster} | R Documentation |
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 = 30L)
Arguments
wkt |
Character. OGC WKT string for a simple feature 2D geometry. |
dist |
Numeric buffer distance in units of the |
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.
