The Current State of the Art in UAS-based Laser Scanning

Airborne Laser Scanning with a UAS
Airborne laser scanning (ALS) offers a range of opportunities for mapping and change detection. However, due to the large costs typically associated with traditional ALS, multi-temporal laser surveys are still rarely studied and applied. Unmanned aerial systems (UASs) offer new ways to perform laser scanning surveys in a more cost-effective way, which opens doors to many new change-detection applications. What are the differences in suitability between the two main types of UAS platforms – fixed-wing systems and rotorcraft – and what is the current state of the art in UAS-compatible laser scanning systems? Read on to find out. (By Antero Kukko, Anttoni... (read more)

Strong Emphasis on R&D in Lidar

GIM Interviews Dr Allan Carswell, Optech Incorporated
Since its 1974 ‘spin-off’ from the Physics Department of York University in Toronto, Optech has grown to become a world leader in the development, manufacture and sale of advanced laser-based instruments and products incorporating pulsed, time-of-flight laser radar (Lidar) systems. Strong emphasis on R&D has led to these being applied in a wide range of applications. The company has received awards for business excellence, innovation, R&D and university collaboration. How big is your company in terms of number of employees and market share, who are your main clients and how is your customer-base distributed over the continents? With over two... (read more)

Chasing BIM: How Surveyors Can Shape the Future

Greater Utilisation of Technologies at Hand
While research shows that many organizations recognise the power of building information modelling (BIM) for streamlining construction and infrastructure projects in a seamless online environment, survey and geospatial professionals can do more to deliver value in the 3D environment. There have been countless presentations and papers on the definition of BIM. This article makes an attempt to provide some practical insights on how surveyors can leverage the BIM revolution to benefit their businesses. The good news: there is a general consensus among geospatial thought leaders that the design and construction industry has reached a tipping point. The more that surveyors... (read more)

Object-based Classification of Point Clouds

Augmenting 3D Geometry with Semantic Information
Today, the analysis of 3D point clouds acquired with topographic Lidar or photogrammetric systems has become an operational task for mapping and monitoring of infrastructure and environmental processes. Numerous applications require the identification and delineation of landscape objects and their properties. So far, many software solutions have been focused on the analysis of constructed and man-made objects, which are characterized by a regular and well-defined geometry (e.g. buildings, roads and other infrastructure). In comparison, the detection and analysis of natural landscape objects is challenging, since object boundaries might be fuzzy and the object characteristics within one class can be very...

Laser Scanning of Damaged Historical Icons

Surveying Technology Is Heading for Maturity
Terrestrial laser scanning is becoming an increasingly preferred surveying technique for the 3D documentation of historical buildings. 3D point clouds provide a wealth of information which advanced 3D mapping software can exploit in a relatively simple way, at least when compared to the tedious surveying techniques of the past. However, effective cooperation between architects and the survey team of experts is necessary in order to get the best out of this geodata acquisition technology. In this article, the authors first provide an overview of equipment based on the size of the site and the surveying aim, and subsequently give four... (read more)

UAVs: Where to Focus on Next?

New Technologies Require New Knowledge and Regulations
In June 2018, RSPSoc's 'Photogrammetric Record' publication devoted 11 pages to determining which term they would use for drones. They ultimately decided on ‘unmanned aircraft system’ or ‘UAS’. However, the mere fact that this required 11 pages goes some way towards highlighting the complexity and cross-discipline potential that drones bring, not only to the remote sensing industry but also for multiple other uses, writes Peter Kinghan. Over the past decade we have seen a number of drone uses come through the tried-and-tested period, resulting in unmanned aerial vehicles (UAVs) becoming a proven technology for a range of industries and professions,...

Geomatics Developments in Asia

14th International Scientific and Technical Conference 'From Imagery to Map: Digital Photogrammetric Technologies'
The International Scientific and Technical Conference was held for the 14th time from 20-23 October 2014 in Hainan, China. This year’s conference, which was themed ‘From imagery to map: digital photogrammetric technologies’, was opened by Victor Adrov, managing director and co-founder of Racurs, Moscow, along with SmartSpatio from Beijing, China, as organiser of the event. One of the features of this event is the shift of venue every year; 2014 was its first time in Asia, and China was chosen because of its rising influence on the geomatics market. Prof Chen Jun, National Geomatics Center of China, not only addressed... (read more)

Modern Geodesy: Formula 1 Geospatial

GIM International Interviews Chris Rizos
Chris Rizos, new president of the International Association of Geodesy (IAG), is advocating ‘modern geodesy' and a stronger, more visible role for the IAG. GIM International met Rizos in an early June Cape Town, where he was addressing a crowd of South African surveyors at AfricaGeo, just two weeks after starting his journey to one of the most northern countries of the continent, Marrakech, Morocco, to join the FIG Working Week.   How important is it for you to be in Africa? It's very important. Geodesy is much more a global enterprise than, for instance, photogrammetric or SDI activities. The... (read more)
