public class StcObsDataLocation
- extends Stc
Java interface to the AST StcObsDataLocation class
- correspond to the IVOA ObsDataLocation class.
The StcObsDataLocation class is a sub-class of Stc used to describe
the coordinate space occupied by a particular observational dataset.
An STC ObsDataLocation element specifies the extent of the
observation within a specified coordinate system, and also specifies
the observatory location within a second coordinate system.
The AST StcObsDataLocation class inherits from Stc, and therefore
an StcObsDataLocation can be used directly as an Stc. When used
in this way, the StcObsDataLocation describes the location of the
observation (not the observatory).
Eventually, this class will have a method for returning an Stc
describing the observatory location. However, AST currently does not
include any classes of Frame for describing terrestrial or solar
system positions. Therefore, the provision for returning observatory
location as an Stc is not yet available. However, for terrestrial
observations, the position of the observatory can still be recorded
using the ObsLon and ObsLat attributes of the Frame encapsulated
within the Stc representing the observation location (this assumes
the observatory is located at sea level).
