GetCoordExtent Method

Description

Gets the extents corresponding to a coordinate format string.

Syntax

Public Function GetCoordExtent( _
   ByVal coordClass As String, _
   ByVal coord As String _
) As String

Parameters

coordClass

The coordinate format class to use in interpreting the coord argument.

 

AGridAxes	Coordinate Grid
AGridGrid	Grid item (e.g. DTM or DEM)
AGridIrish	Irish Grid
AGridJapanDM	Japanese Digital Map
AGridJapanPC	Japanese General Area Mesh
AGridLatLon	Latitude/Longitude
AGridPath	Linear coordinates
AGridNatGrid	OS (GB) National Grid
AGridBearing	Polar coordinates
AGridBearingRelative	Relative polar coordinates
AGridSurvey	Survey coordinates
AGridWgs84	WGS84 Latitude,Longitude,Height

 

coord

The coordinate string, in the format specified by the coordClass argument, to be interpreted.

Return Type

A comma-delimited string containing a pair of x, y and z coordinates describing the extents of the coordinate format position. Use SplitExtent to get the pair of x, y and z values themselves. If the coordinate format position describes a point then the extents will describe the same point.

The supported coordinate formats can be found using the _CoordClasses$ system variable (the coordinate format class to use in interpreting the coord argument). See Coordinate Grids for more details.
