A Position element contains information about a 1d, 2d, or 3d position for a node. In general a different position record is used for each datum and source. For example if a 3d adjustment was the source a single 3d position record (e.g. lat, lon, ellipsoid ht) could be used. If there was an AHD height determined this would be a separate 1d position record.

A node is an abstract entity used to identify the aggregation of measurement and position associations to a site for the purpose of coordinate estimation. The resultant position estimations that are assigned to a node express the position of the site reference point according to the authorities that instantiated the node and performed the estimation for a valid time.To represent a "current node" whereby the begin position for the valid time is known but the end position is not known, it is conventional to use the following example structure:<gml:validTime><gml:TimePeriod gml:id="id"><gml:beginPosition>2015-03-30Z</gml:beginPosition><gml:endPosition indeterminatePosition="unknown"/></gml:TimePeriod></gml:validTime>

A Site is the umbrella element containing all physical information about a particular observing system site. All setups, nodes and observation quality elements reference a site. Conversely, measurements and positions do not reference a physical site but rather they reference the node abstraction. There can be more than one node that references the one site, but each node must have a unique authority. E.g. Yarragadee CORS can have a Reg13 node (or site certificate) and a national adjustment node. Both reference the same site and thus simultaneously reference the same setup and observation quality, but the estimated coordinates and velocities with associated quality can be different and this is dependent on the business rules of the authority.

This properties group is shared by geo:PositionType and geo:PositionTimeSliceType.A coordinate reprojection should be only permissible under the following constraints:1) A new status is generated and added to the position element stating that the coordinates are re-projected or transformed.2) Along with the above, the source element must be present and contain (a) an xlink to the original position and (b) a reference to the projection/transformation method.3) If the quality element is present in the original coordinate instance then it must be transformed using the same parameters but using the transformation method appropriate to the quality type (PU, VCV etc)4) If a hasVelocity element is present in the original coordinate instance then velocity and associated quality must be transformed using the same parameters but using the transformation method appropriate to velocity.If the above three conditions cannot be met by the WFS, the position element should not be transformed. Perhaps an error or notice should be issued (or appended to the position) stating that the reprojection was unsuccessful due to limitations of the WFS implementation.
