theCoordinateUnits

char ossimNitfGeoPositioningTag::theCoordinateUnits[4]

protected

FIELD: UNI.

required 3 byte field.

Coordinate Units This field shall contain the units of measure to which the Image Segment refers. Valid values are SEC (Decimal seconds of arc), DEG (Decimal degrees) and M (Metres). The value must be consistent with the coordinate system type. SEC and DEG are not allowed when the coordinate system type is MAP. M is not allowed when the coordinate system type is GEO. The PRJPS extension is expected when the value is M. The default value is M.
