result = cgShapeRange( [shapefile] [, MEAN=float] [, MEDIAN=float] [, XRANGE=float] [, YRANGE=float])
Determines the X (longitude) and Y (latitude) data range of the entities in a shapefile.
Return value
A four-element array containing the extent of the entity data in the shapefile, in the order [xrange[0], yrange[0], xrange[1], yrange[1]].
Parameters
- shapefile in optional type=string
The name of the shapefile for which you wish to know the extent. If not provided, the user will be asked to pick a shapefile.
Keywords
- MEAN out optional type=float
A two-element float or double array giving the mean or average X value and the mean or average Y value of the entities in the shapefile, respectively
- MEDIAN out optional type=float
A two-element float or double array giving the median X value and the median Y value of the entities in the shapefile, respectively
- XRANGE out optional type=float
A two-element float or double array giving the minimum and maximum extent of the shapefile entities in the X (longitude) direction, respectively
- YRANGE out optional type=float
A two-element float or double array giving the minimum and maximum extent of the shapefile entities in the Y (latitude) direction, respectively
Examples
shapeBoundary = cgShapeRange('states.shp')
