Geoprofessionals Should Look Ouside Their Own Box

Jantien Stoter Bridges The Gaps
Having specialised in 3D GIS, Jantien Stoter has already taken her next leap and is now studying the concept of 5D GIS. Meanwhile, she realises that there are still some gaps to bridge between technical sciences and practice. A highly technical person herself, she shares her views on which directions geoinformation professionals should be looking in to keep the field alive. She recently finished the first phase of a pilot on a 3D standard for The Netherlands' spatial data infrastructure involving nearly 70 stakeholders. The second phase is currently examining how to put the results of the first phase into... (read more)

Statutory versus Customary II

Institutional Weaknesses in Nepal
Of the roughly thirty million people living in Nepal, a majority belongs to peasant households and lives below the international poverty line of $1.25 a day. The peasant population has also, under former customary land tenure arrangements, been exploited and pauperised. Land related statutory acts introduced since 1951 have not brought security of rights for the actual cultivators of the land, and thus discourage investment in it. Thanks in part to institutional weaknesses, land administration services are today distrusted by the population. The author inventories these weaknesses and provides suggestions for solution. For many centuries farming has been the principle... (read more)

A Brilliant Career

GIM International interviews Gottfried Konecny
Professor Gottfried Konecny, one of the most respected names in photogrammetry, shares some reflections on his work and profession. He worked in post-war Neumarkt as a teenage draughtsman, was chief surveyor on the 1965 Canadian Mount Kennedy expedition, mapped the lunar landing site at NASA, and has been involved in nearly all the European space mapping missions. And these are just some of Professor Gottfried Konecny’s extraordinary achievements. Today emeritus professor at the University of Hannover, he shares withGIM Internationalsome of the highlights of a career in photogrammetry that has spanned well over six decades.<P> Why did you choose a...

How Google Gave Geography its Groove Back

GIM International interviews Ed Parsons
Once upon a time, the study of the Earth's surface, its features, inhabitants and phenomena was nothing more than a tiresome school subject for the average person on the street. Google has changed all that with its interactive map of the world. Stitched together from aerial and satellite footage, it has been downloaded more than 400 million times, with people and organisations putting it to all sorts of interesting uses, from spying on celebrities to locating the nearest hotel in a foreign city. We spoke to Ed Parsons, Google's geospatial technologist, to find out more about what lies ahead for... (read more)

Object-based Classification of Point Clouds

Augmenting 3D Geometry with Semantic Information
Can object-based classification of point clouds offer an alternative to classification of individual points when detecting and analysing natural landscape objects? 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... (read more)

On-the-fly Decision Support in Flood Management

Combining Methods for Fast Simulation and 3D Visualisation
This integrated flood simulation and visualization system provides answers on the fly and presents 3D visualizations that even non-experts can understand. In flood and storm water management, simulation is widely used for flood risk assessment, for designing mitigation measures and for sustainable urban planning. In this context, live sessions are an effective tool for collaboration between domain experts and decision-makers to discuss and develop new ideas. This article presents an integrated flood simulation and visualization system that is able to provide answers to the questions of experts and stakeholders on the fly. It supports fast incorporation of new parameters through... (read more)

Web GIS Improves Lidar Collection Response Time

The LMAP Initiative
The remarkable capabilities of airborne Lidar continue to improve, with scanners now able to emit more than a million pulses every second. Although it has never been easier to acquire high-quality laser data, storing and managing the huge volume of Lidar data collected can prove to be a challenge. Combined with associated metadata such as survey information, environmental conditions and flight lines, data management has now become a critical priority and focus. This article outlines a new initiative called LMAP that provides an automated workflow for uploading and storing Lidar and metadata into GIS. Developed in a partnership between RIEGL of...

Chasing BIM: How Surveyors Can Shape the Future

Greater Utilisation of Technologies at Hand
Survey and geospatial professionals can still do more to deliver value in the 3D environment. Learn how to leverage the BIM revolution for business benefits with these practical insights. While research shows that many organizations recognize 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... (read more)

Use of GIS in Smart City Projects

Managing and Visualising Geospatial Data in a User-friendly Environment
A geographic information system (GIS) has been used in the construction of a large-scale model of a smart city project in France. The smart city concept is developing very quickly around the world, because it provides a comprehensive digital environment that improves the efficiency and security of urban systems and reinforces the involvement of citizens in urban development. This concept is based on the use of geospatial data concerning the urban built environment, the natural environment and urban services. The successful implementation of a smart city project requires the development of a digital system that can manage and visualise the... (read more)
