Remarks

QueryOffsetPoint returns the spatial location of an NALocation after applying the offset distance and units specified.  If the location occurs along a line, the (input location parameter) INALocation.Side property indicates whether the offset occurs to the left or right of the digitized direction of the line.  In other words, if the location is on the left side, the offset occurs to the left.  For locations on junctions, nothing is offset.

Generally, the NALocator should be retrieved from a NAContext.  However, if you do create a NALocator, or have added a new locator agent, then, before querying the NALocator, Bind should be called on the NALocator to set up the agents and associate it with the NetworkDataset.

The output geometry is returned in the spatial reference of the network dataset.  Optionally, set an OutputSpatialReference on the NALocator.
