Articles and useful resources on Geomatics, Land Surveying, Geodesy and Mapping.

Geomatics is the discipline concerned with the collection, distribution, storage, analysis, processing, presentation of geographic data or geographic information.

ISO/TC 211 (reference: ISO/TC211/WG1 N119)

The discipline of Geomatics encompasses the fields of surveying, mapping, remote sensing (Laser Scanning), photogrammetry, hydrography, GNSS, GIS and many more.

What does a Geomatics Engineer do?

Geomatics Engineers, sometimes called Engineering Surveyors, gather, model, analyze, and manage information that is identified according to its location (spatially referenced data). They do this by making use of sensors on the ground, in the air, in the ocean and on satellites. Sensors in these categories include topographical instruments (e.g. total stations), GNSS (GPS) equipment, laser scanners, drones and even the very basic measuring tape.

Geomatics vs Surveying

You might wonder what the difference is between Geomatics and Surveying? Land Surveying (or Engineering Surveying) is in fact a sub-discipline of Geomatics. However, in practice, there is little to no difference between the disciplines and the terms get used interchangeably often.

Importance of Geomatics

Why is Geomatics important or what is the purpose of it? In short, whenever there is a requirement of location information Geomatics comes into play. Having precise locations defined on the surface of the Earth is critical in many fields and industries such as: cartography, land boundaries, disaster management, navigation, energy assessment, noise and pollution monitoring and many more. A Geomatics engineer will make use of sensors, knowledge and software to produce highly accurate positional information for any of these scenarios.

This is a large encompassing discipline that has been evolving continuously throughout the years. Applications are in continuous development and technology advancements only make it better every day.

In these pages you will find useful information and tools, regardless if you are in the profession or not.

  • GNSS vs GPS – what is GNSS?
    GNSS (Global Navigation Satellite Systems) is a term used to describe satellite-based systems that provide positioning, navigation, and timing (PNT) data. GNSS is widely used in geomatics and land surveying to accurately determine the position and orientation of points on the Earth’s surface. Other uses outside of land surveying include transportation, navigation applications, agriculture and weather forecasting.
  • Survey Field Books & Field Notes
    Surveying is all about observations. When you go on site, you often need to record not just topographical data, but also notes about your work. Good record keeping is a must have in land surveying, and this is best achieved by always taking essential field notes in your survey field book.
  • Converting SnakeGrid Coordinates
    Converting to and from SnakeGrid coordinates might seem a like a difficult task when you’ve never done it, but it’s actually quite a simple procedure. In this article I will explain how to do different conversions to and from SnakeGrid coordinates.
  • AutoCAD – How to fillet elements with the Fillet Tool
    A filet is term used in many industries and can be defined in different ways, but it simple terms it is a rounded sharp edge or corner. In this article I will explain the fillet tool in AutoCAD & how to fillet 2D and 3D elements.
  • SnakeGrid – The Ultimate Guide
    If you’ve worked on large engineering projects that span over long but narrow areas, you probably have had difficulties using projected coordinate systems in your surveys.…In this article I will explore the meaning of SnakeGrid. I will go over topics like: what is the Snake Grid Coordinate System, what SnakeGrid coordinates are, what are the Snake Grid types out there and SnakeGrid converter software.
  • What are Land Surveyors? 👷
    At their very core Land Surveyors do measurements. To be more specific, a surveyor gathers positional data to produce accurate representation of the shape of the land and anything on it. Whilst the term surveyor is all encompassing, there are other terms that are used to describe surveyors.
