bboxSpatialPolygon: Convert a bounding box to a SpatialPolygons object Bounding box is first created (in lat/lon) then projected if specified

Description

Convert a bounding box to a SpatialPolygons object Bounding box is first created (in lat/lon) then projected if specified

Usage

bboxSpatialPolygon(boundingbox, proj4stringFrom = NULL, proj4stringTo = NULL)

Arguments

boundingbox

Bounding box: a 2x2 numerical matrix of lat/lon coordinates

proj4stringFrom

Projection string for the current boundingbox coordinates (defaults to lat/lon, WGS84)

proj4stringTo

Projection string, or NULL to not project

Value

A SpatialPolygons object of the bounding box
