R Documentation

Obtain the 2D or 3D bounding envelope for input geometries

Description

g_envelope() computes and returns the bounding envelope(s) for the input geometries. Wrapper of OGR_G_GetEnvelope() / OGR_G_GetEnvelope3D() in the GDAL Geometry API.

Usage

g_envelope(geom, as_3d = FALSE, quiet = FALSE)

Arguments

`geom`	Either a raw vector of WKB or list of raw vectors, or a character vector containing one or more WKT strings.
`as_3d`	Logical value. `TRUE` to return the 3D bounding envelope. The 2D envelope is returned by default (`as_3d = FALSE`).
`quiet`	Logical value, `TRUE` to suppress warnings. Defaults to `FALSE`.

Value

Either a numeric vector of length 4 containing the 2D envelope ⁠(xmin, xmax, ymin, ymax)⁠ or of length 6 containing the 3D envelope ⁠(xmin, xmax, ymin, ymax, zmin, zmax)⁠, or a four-column or six-column numeric matrix with number of rows equal to the number of input geometries and column names ⁠("xmin", "xmax", "ymin", "ymax")⁠, or ⁠("xmin", "xmax", "ymin", "ymax", "zmin", "zmax")⁠ for the 3D case.
