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...

Water Crossing Surveys at a New Level

First Order Height Transfer With Sighting Distances Above One Kilometre
When establishing heights on large geodetic networks, the main problem surveyors encounter are wide bodies of water, such as rivers, that need to be crossed without losing accuracy. Thanks to special procedures these kinds of crossings have been successfully done in the past using levelling instruments and total stations, but seldom at a first order level when distances exceed one kilometre. Combining conventional instruments with digital camera's and image processing now brings transferral of heights with first order accuracy within reach, even with sighting distances of over one kilometre.   In June 2011, Henk ten Damme, a Dutch authority on...

Intergeo 2006 - Preview

10th - 12th October, Munich, Germany
‘Knowledge and Action for the Earth’ is the theme of Intergeo 2006, the annual geodesy and geo-information conference and trade-fair organised in association with the German Association of Surveying (DVW) and taking place from 10th to 12th October. Roaming as it does annually from one major city in Germany to another, Intergeo this year settles in Munich, world-renowned Bavarian capital of science, technology, arts and culture and, last but not least, the October Beer Festivals. Almost fifteen thousand visitors are expected to come together at the Neue Messe Convention Centre, the same number as attended the ESRI International User Conference... (read more)

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)

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)

State-of-the-art Total Stations

A Look At New Technologies
In the last few years, the computer revolution has brought about a different approach to engineering and construction projects. Thanks to automated processes, engineers can now produce a much higher level of detail and accuracy in their projects. These changes have significantly increased the level of responsibility within the role of land surveyor in particular. Surveyors nowadays have more data and information to handle while facing ever-increasing demands for high-quality topographic products such as construction site surveys, land ownership and utility management. One of the most important tools surveyors use is the total station which, having been used for decades... (read more)

Robotic Theodolites (RTS)

Measuring Structure Excitation
Robotic theodolites, the new generation of the well-known surveying theodolite, are used to measure deflections in short-span bridges with millimetre accuracy. This permits the coming true of an old dream for engineers: to be in a position not only to predict, but to measure the excitation of engineering structures due to dynamic loads such as wind and traffic, and hence evaluate their structural health.     Electronic theodolites or total-stations (TS) are very common survey instruments used to compute the Cartesian coordinates of selected points marked by a usually prismatic reflector. A TS emits a modulated IR ray to the... (read more)

Total Solution from a Single Window

SECON Private Limited is an ISO 9001:2008, CMMI Level 3 and NAB-accredited firm which was established in 1981. Headquartered at Bangalore, India, it is a financially sound and zero-debt multidisciplinary engineering consulting firm. SECON is the oldest and largest commercial mapping and investigation firm in India and is also one of the country’s leading companies for civil engineering consulting. Initially, SECON was involved in land surveys for infrastructure projects and focused particularly on pipeline and irrigation mapping. It later moved into geotechnical investigations and water resource engineering, and in 2000 SECON diversified into highway engineering and construction supervision. SECON has... (read more)

Spatial Cave Mapping in Bulgaria

Modern Methods and Devices
Caves are natural underground spaces formed and shaped over millions of years. Usually part of bigger caverns, they give a first-hand view of water, biology, oil and other subsurface distributions as well as a glimpse of the past when they perhaps offered shelter or sanctuary. Therefore, when exploring a cave, it is useful to not only collect geometric information such as gallery dimensions and directions but also to take photographs and notes of any specific features of interest. Since safe storage, easy management and proper representation of spatial data can be difficult using traditional methods, these are all key requirements... (read more)

Intergeo 2009: ALS, TLS and MLS

Intergeo 2009 took place in Karlsruhe from 22nd to 24th September with a conference and trade-fair. And despite the ongoing credit crunch, this fifteenth Intergeo exceeded all expect­ations of the organisers, the German Association of Surveying - German Society for Geodesy, Geoinformation and Land Management (DVW) and HINTE GmbH. If you missed Intergeo 2009, or are still dizzy from the cacophony of colours, lights and company names bombarding you from the 475 exhibitors this year crammed into apparently ever shrinking stands, you have only to remember three abbreviations that we feel shaped the lead theme of this year’s show: Airborne...
