North of origin on selected grid (in meters).
The coordinate is based on the selected grid. Before reading or writing to this property
Position.Grid or Position.CustomGrid must be specified.
If Position.Grid uses a zone, Position.Zone must be set as well.
When setting a new value latitude/longitude will change to represent the same position as the grid coordinates.
In this way you can convert grid coordinates to latitude/longitude.
SPCS27 (State Plane Coordinate System 1927) is measured in U.S. feet. To convert between feet and meters
use the following constant: US_FOOT = 0.30480061
distance_us_feet = distance_meters / US_FOOT
distance_meter = distance_us_feet * US_FOOT
International foot: INT_FOOT = 0.3048
Irish foot: IRELAND_FOOT = 0.3048007491
Those constants are defined in "modConst.bas"
v = object.Northing
object.Northing = v
||An object that evaluates to an GpsToolsNET.Position object.
||North of origin on selected grid (in meters).
