OTIC Surveys

📍Surveying is more than just standing behind an instrument.

From setting up equipment and taking precise measurements to identifying points and checking boundaries, every step matters in getting accurate results.

At OTIC Surveys, we understand the work, skill, and attention to detail that go into every survey.

Every point matters. Every measurement counts.

Total Station vs. Theodolite — do you know the difference?

Both measure angles, but a Total Station also uses electronic distance measurement (EDM) to measure distances and determine positions.

Understanding the difference helps you choose the right instrument for your surveying task.

What’s the Difference: Open Traverse vs. Closed Traverse?

One follows a route without closing, while the other closes on itself or connects to a known control point.

Do you know when to use each method? 👀

MSL or Ellipsoidal Height — what’s the difference?

Both describe height, but they use different reference surfaces.

MSL — height referenced to mean sea level.
Ellipsoidal Height— height referenced to the Earth’s mathematical ellipsoid.

Understanding the reference behind your height value matters, especially when working with GNSS and elevation data.

What’s the difference? Now you know.

Site Plan or Survey Plan — do you know the difference?

They may both show information about a property, but they serve different purposes.

A survey plan establishes the land’s boundaries, measurements and coordinates, while a site plan focuses on the existing and proposed arrangement of the property.

Knowing which document you need can save you confusion when buying, developing or working on a property.

What’s the difference? Now you know.

September took OTIC places. 🌍

From project sites across Nigeria, to Ghana, and all the way to Frankfurt, Germany — it was a month filled with fieldwork, training, events, exhibitions, and plenty of movement.

And somehow, we still found time for the great jollof debate. 😂

🎬 Here’s September, Recapped with OTIC.
