The Digital Cadastre: Will Property Surveys Go Electronic Too?

South Africa's move to electronic deeds registration under eDRS has put the spotlight on one half of the property system — the deeds, which record who owns what. But every property rests on a second system that's just as important and far less talked about: the cadastre, the national record of where each piece of land actually begins and ends. As the deeds side digitises, it's worth understanding how the two fit together and what "going electronic" means for surveys.

Two systems, one property

Every registered property in South Africa is defined by two parallel records:

• The deeds record — held by the deeds office, it records ownership, bonds and conditions. This is the part eDRS is moving to an electronic lodgement and registration system.
• The cadastre — maintained through the Surveyor General system, it records the surveyed geometry of the land: the boundaries, beacons, extent and servitudes captured on each property's Surveyor General (SG) diagram or general plan.

The two are linked but distinct. Your title deed references the SG diagram that defines your boundaries, but the deed and the diagram live in different systems maintained by different offices. Electronic deeds registration changes how the deeds side works; it does not, by itself, replace the survey records.

Where the survey records already are digital

Much of the cadastral record has been captured and digitised over the years — surveyed coordinates, diagrams and general plans increasingly exist in electronic form behind the scenes, which is precisely what makes instant diagram retrieval possible. In practical terms, you no longer have to visit an office to obtain a diagram: you can look up and download the SG diagram for a property online at SGCheck. The underlying survey was done long ago; what's changed is that getting hold of the record is now fast and digital.

What a fully electronic future could look like

The logical end-point of digitising both halves is a property record where ownership and boundaries are linked, electronic and queryable together — the deed and the diagram joined up rather than chased through separate systems. eDRS is the deeds half of that picture. A modern, electronically accessible cadastre is the other half. The closer those two move, the simpler property due diligence becomes: one search for who owns it, one for where it runs.

That's also the long-term thread behind ElectronicDeeds — the move from paper to electronic isn't a single switch but a gradual joining-up of the records that define a property.

What it means for you today

You don't have to wait for a unified future system to use either half right now:

• To check who owns a property, whether there's a bond, and its transfer history — that's a deeds search at DeedsCheck.
• To check where the boundaries run, the extent and any servitudes — that's the SG diagram, available at SGCheck.

Both are already online and instant. The electronic transition is making each easier to reach; understanding which record answers which question is what lets you use them well.

Frequently asked questions

Does eDRS include property survey records?

eDRS is about electronic deeds registration — ownership, bonds and conditions. The survey records (boundaries and extent) are part of the cadastre, a separate system maintained through the Surveyor General. The two are linked but distinct.

Can I get an electronic copy of an SG diagram?

Yes. Survey diagrams are available digitally — you can look up and download the SG diagram for a property online at SGCheck, by address or erf number.

What is the cadastre?

The cadastre is the national record of where every piece of registered land begins and ends — the surveyed boundaries, beacons and extent captured on SG diagrams and general plans. It sits alongside the deeds record, which deals with ownership.

Will deeds and survey records ever be one system?

They're separate today, but both are digitising. The practical effect for you is that each is already searchable online — deeds at DeedsCheck, diagrams at SGCheck — even though they remain distinct records.
