Technologies for the Future: A Lidar Overview

Building the Capability for High-density 3D Data
Point clouds can be captured by an ever-increasing number of means to understand the surrounding reality and detect critical developments. Diverse applications of 3D laser scanning or ‘Lidar’, which is a technology on a sky-rocketing path to be used for mapping and surveying, are changing the way we collect and refine topographic data. Which technologies and processes are building the capability for high-density 3D data? This article outlines the latest industry developments. National topographic databases store data refined from field measurements, imagery and laser scanning data at certain specifications and purposes, but lack the ability to adapt to ever-changing needs...

Capturing Geospatial Data from Vehicle Platforms

Jacobs’ Journey
Jacobs Geomatics provides support and consultancy to the company’s wider design and engineering services. In recent years Jacobs’ UK geomatics team has been involved in increasingly large infrastructure schemes, typically supporting preliminary and detailed design phases of projects. This requires advising on solutions and the subsequent provision of suitable geospatial data. As the projects have grown in scale and complexity, the company has increasingly sought to supplement traditional topographical survey capture techniques with rapid data techniques such as terrestrial laser scanning, aerial photography and Lidar. Over the past three to four years, Jacobs has also become increasingly involved in vehicle-mounted... (read more)

Exceeding All Limits

Intergeo 2005 Düsseldorf, Germany – A Preview
This year’s Intergeo, to be held at the Exhibition Centre in Düsseldorf, Germany from 4th to 6th October, is expected to exceed all limits. With opening extended to three whole days and exhibition space to 10,000m2, it certainly looks as though big things are expected. And if organiser Hinte-Messe predictions prove correct, some 17,000 visitors and 1,500 conference delegates will attend. Nearly five hundred exhibitors have booked a stand at the trade-fair. It is not only in statistics limits are being pushed. The theme of ‘Exceeding limits’ reflects a wish to increase awareness of European expansion, globalisation and its effect... (read more)

Google Earth

What GI Professionals Can Gain From It
Google Earth has been mentioned at least once at every meeting or conference of GIS-related professionals I’ve attended over the past year. It was even briefly referred to during defence of a PhD thesis on SDI clearinghouses. Google Earth is about business, technology, mapping, cartography, leveraging and integrating spatial data and internet. Reasons enough to take a closer look at the search engine from a personal geo-information perspective. The moment someone told me about Google going GIS was an exciting one for me and for many others in the professional Geo-Information (GI) community. Why? Because our discipline was suddenly receiving... (read more)

Geospatial Data as a Core Instrument to Transform a Country

Interview with Borko Drašković, General Director of the Republic Geodetic Authority (RGA), Serbia
After several turbulent decades, the Republic of Serbia is working towards a brighter future, including by radically transforming its geospatial information infrastructure. In fact, the country has received recognition for its reforms in the process of digitalization and economic development of the state. This confirms the role of geospatial data as a fundamental 21st-century resource with considerable potential for economic and social development of state and society. In this interview with Borko Drašković, general director of the Republic Geodetic Authority (RGA), 'GIM International' takes a closer look at the achievements in Serbia, which can serve as an example for other...

Standards Are a Great Help for Establishing Land Administration

GIM International Interviews Christiaan Lemmen
In 2017 Dr Christiaan Lemmen, a former contributing editor of 'GIM International', was appointed as professor of land administration modelling at Twente University’s Faculty ITC for Geo-Information Science and Earth Observation. He is the leading designer of the ISO 19152 international standard for geographic information – Land Administration Domain Model (LADM), the second edition of which has been in development since 2018. In this interview, he discusses the importance of LADM standards, poverty and tenure security, and the long and winding road to put well-functioning land administration in place in developing countries. The Land Administration Domain Model is actually an... (read more)

INSPIRE Boosts Spatial Data Sharing

GIM International interviews Joeri Robbrecht
The INSPIRE Directive was introduced in 2007 and should reach full implementation in 2020. Today, over halfway through the process, various important milestones have already been achieved while others still lie ahead. GIM International took the opportunity to join Joeri Robbrecht, policy analyst for the DG Environment of the European Commission, in reflecting on the journey so far and looking ahead to the future direction. Read on for the interview. What is the European Commission’s opinion of the current state of implementation?  The European Commission has assessed the state of implementation and the fitness of the INSPIRE Directive for its...

Laser Scanner in a Backpack

The Evolution towards All-terrain Personal Laser Scanners
Evolution of Laser scanning: new prototype which can be held in a backpack for rugged terrain. Laser scanning systems have gone through a major evolution in the past decade. After the initial breakthrough of airborne laser scanners (ALS), other types of laser scanning systems have emerged, most notably terrestrial laser scanners (TLS) and mobile laser scanners (MLS). While these three main types of Lidar systems together serve a large number of applications, none of them are optimised for fast and flexible scanning in challenging locations, rugged terrain and complicated urban structures. Personal laser scanners (PLS) fill this void and are now evolving towards compact, agile and flexible solutions for mapping complex environments. This article explains the... (read more)

Kadaster: Ambitions and Goals

Leading Role for Key Registers
Programmes at European and national government level are signalling opportunities, setting policies and taking measures to capture the benefits of ICT. In tandem with societal demands, this will lead to government services via internet, key registers, web services and more. The author sketches the ambitions and goals of the Netherlands Cadastre (Kadaster) against a background of European policy, ICT developments and customer expectations. ICT offers many opportunities for improving the performance of government and business. Areas which may profit include education, safety, health care, international co-operation, economic efficiency (integrated value chains, business-process management, reduction in administrative overheads), prevention and detection...

Light Mobile Collection Tools for Land Administration

Proof of Concept from Colombia
Need for administration of property: estimated 75% of the relations between people and land not documented. There is an urgent need for the administration of property and land use rights worldwide as the basis for social and economic growth. Notwithstanding the enormous investments by governments and international organisations in the development of such systems over the past decades, it is still estimated that, from a global perspective, 75% of the relations between people and their land are not documented. So which methods and techniques can be used to develop land administration systems for all, and within our generation? Light mobile collection tools may offer a solution, as presented in this proof of concept from Colombia. By... (read more)
