mapbbox - Compute bounding box of georeferenced image or data grid

Syntax

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 spatialref.MapRasterReference 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
