The Surveyors of Our World

A Journey through History
In today’s data-driven society, in which location-based services have become an omnipresent part of everyday life, there is no doubt that surveying is all around us. But did you also know that surveyors have been indispensable to the development of the world since civilization began? In this brief journey through history, John F. Brock provides a surprising and entertaining look at the importance of surveying through the ages, from ancient times up to the modern day.     It is not difficult to conjure up an image of how people in ancient civilizations may have divided up their lands. They certainly... (read more)

Towards Cadastral Intelligence?

Extracting Visible Boundaries from UAV Data through Image Analysis and Machine Learning
The inability to access formal land registration systems fosters insecure land tenure and conflicts, especially in developing countries. This calls for low-cost and scalable mapping solutions aligning with fit-for-purpose land administration. The work presented in this article supports the UAV-based mapping of land tenure inspired by state-of-the-art approaches from remote sensing, geoinformatics and computer vision. The guiding question is how to develop an automated approach that promotes the paradigm shift towards cadastral intelligence which integrates human-based expert knowledge with automatically generated machine-based knowledge. Cadastral mapping contributes to the creation of formal systems for registering and safeguarding land rights. According to... (read more)

Integrating the ‘Constructioneering’ Workflow Together

The How and Why of the Topcon and Bentley Partnership
Digitalisation and new technologies with the ability to revolutionise the geospatial industry are creating a new playing field for mapping and surveying professionals. This evolving landscape is also reshaping the industry, with new entrants gaining ground and established players seeking to collaborate and combine their specialist areas of expertise in order to offer a total solution. Wim van Wegen, content manager of ‘GIM International’, met with Ted Lamboo, senior vice president of strategic partners at Bentley Systems, and Ewout Korpershoek, executive vice president at Topcon Positioning Systems, at Bentley’s 2017 Year in Infrastructure Conference in Singapore. They discussed the partnership between... (read more)

Surveying in the Mining Sector

An Overview of Geospatial Methods in Mining Engineering
Geospatial data forms the foundation of mining. The rapidly evolving innovations in the geomatics sector are bringing previously unforeseen opportunities that will provide a major boost, both to mining surveyors and the mining industry as a whole. Read on for an article which starts with some history – after all, we should never forget where we came from. It then goes on to present a general outline of surveying in the mining industry, with a focus on the survey equipment and the technologies that are being used today. Surveyors in the mining industry fulfil an essential function since they provide... (read more)

Total Stations: the Surveyor’s Workhorse

Features, Status and Trends
A total station is an angle measuring device, also known as a theodolite, integrated with an electronic distance measurement (EDM) unit. The integration provides the ability to measure horizontal and vertical angles as well as slope distances using the same device at the same time, which benefits the surveyor in terms of portability, convenience and speed. Today, total stations have a wide variety of capabilities and are extensively exploited in cadastral surveying, civil engineering and on construction sites. Read on for a synopsis of features, status and trends. For many decades, and up until the 1960s, theodolites were the major... (read more)

Recent Advances in Geodata Acquisition Technologies

No Information without Data
Today’s geodata acquisition technologies combine microprocessors, computer power, solid state drives, complementary metal-oxide-semiconductor (CMOS) sensors, miniaturisation and many more developments. But demand is just as important as supply, and demand is rapidly increasing in our changing world. Read on for details of recent advances in geodata acquisition technologies. In today's world, we are seeing metropolises cluster to form megalopolises, climate change threatens humans, land and livestock in low-lying areas such as river deltas and valleys, and massively populated areas are prone to earthquakes and landslides. All of these factors are increasing the demand for geodata acquisition. This article starts with total stations, continues... (read more)

UAS Potential in Archaeology

Archaeology entails the recording of the physical remains left by past generations. Traditionally, archaeological exploration has been by excavation. Other survey techniques have recently gained importance in recording remains that are visible above the ground. Examples include prehistoric fields, settlements and burial remains in upland areas, or industrial landscapes, buildings and standing monuments such as stone circles in other areas. It is more than worthwhile to explore the application of unmanned airborne systems (UASs) in archaeology. In the past most recording was done with tape and a 1m planning frame, while a theodolite was a luxury. More recently total stations, GNSS receivers, terrestrial... (read more)

Catsurveys Introduces Rapid Vehicle-based MGPR Innovation

New mobile ground-penetrating radar (MGPR) from Catsurveys Group is challenging traditional approaches to utilities and other subsurface surveying. Catsurveys’ MGPR is a georeferencing system and synchronisation process enabling data generated using a vehicle-towed MGPR system to be combined with a global positioning system (GPS) for maximum accuracy and detail. The International Society for Trenchless Technology's (ISTT) award-winning MGPR system is developed to be a key component for feasibly studies and civil engineering projects, providing a vision of where to carry out intrusive works, letting the user make the best informed decision possible before breaking any ground, reducing risks, costs and...
