mapbbox

Compute bounding box of georeferenced image or data grid

Syntax

bbox = mapbbox(R, height, width)
bbox = mapbbox(R, sizea)
BBOX = mapbbox(info)

Description

bbox = mapbbox(R, height, width) computes the 2-by-2 bounding box of a georeferenced image or regular gridded data set. R is either a 3-by-2 referencing matrix defining a 2-dimensional affine transformation from intrinsic pixel coordinates to map coordinates, or a object. height and width are the image dimensions. bbox bounds the outer edges of the image in map coordinates:

[minX minY
 maxX maxY]

bbox = mapbbox(R, sizea) accepts sizea = [height, width, ...] instead of height and width.

BBOX = mapbbox(info) accepts a scalar struct array with the fields

'RefMatrix'

3-by-2 referencing matrix

'Height'

Scalar number

'Width'

Scalar number
