It is an open-access database of all survey control mark information in Victoria, with search and download options and the ability to lodge new information or amendments. SMES is also used by Surveyor-General Victoria (SGV) to maintain Australia's geodetic and height datums – the Geocentric Datum of Australia 1994 (GDA94) and Geocentric Datum of Australia 2020 (GDA2020) and the Australian Height Datum (AHD).
- latest GDA2020 and the former GDA94 coordinate and AHD height values resulting from ongoing network adjustments
- estimates of positional uncertainty – horizontal and vertical
- additional survey mark information and metadata, such as mark status, observation techniques, source and adjustment details
- underlying VicMap data to support interactive map searching
- permanent mark sketch plans.

Permanent mark sketch plan templates
Plan templates for the preparation of permanent mark sketch plans are available. They have been formatted to suit common CAD software packages. These include AutoCAD (DWG), LISCAD (LCD), Microstation (DGN), PDF, DOC and DXF.
Protection and maintenance of survey control marks
Survey control marks are stable reference points in the ground with accurately measured coordinate and height information. It is important that this valuable infrastructure is protected and maintained to support surveying of property boundaries, mapping and construction activities and to ensure minimal inconvenience to the public.
SGV has prepared a fact sheet detailing the role of council and surveyors in the protection and maintenance of survey control marks.
Submission of GNSS data
Surveyors working with survey control marks in Victoria are encouraged to submit GNSS data to SGV as outlined in this factsheet.
Sample GNSS field booking sheets help ensure all required observation information is provided.
