Point Clouds and Smart Cities

The Need for 3D Geodata and Geomatics Specialists
The ‘smart city’ concept entirely relies on a permanent stream of massive amounts of data acquired by a great variety of sensors distributed throughout the city. Smart use of all this data requires integration with 3D city maps for which point clouds, acquired by laser scanning or photogrammetry, are the main sources. The author of this article identifies the abilities of point clouds to support the smart city concept. The benefits of point clouds for monitoring urban processes were recognised quite early on. Back in the early 1990s, airborne Lidar could accurately provide the height component which is so important... (read more)

Bridging the Gap between Aerial Imaging and Terrestrial Data Capture

The Challenges of Drone Use in Facade Mapping
There have been rapid advancements in unmanned aerial systems over recent years, yet there is widespread consensus that we have still only seen a fraction of how unmanned aerial vehicles (UAVs or ‘drones’) could ultimately improve efficiency for geospatial professionals and their customers. To get a glimpse of the future, 'GIM International' spoke to Mark Nicolai, co-founder of industry start-up Aeroscan. Here, he shares his vision of how drones could form the missing link between aerial imaging and terrestrial data capture. According to independent research by the likes of PwC and Goldman Sachs, the construction industry tops the list in... (read more)

Pioneers in Capturing Public Space

GIM International interviews Frank Pauli, CycloMedia
CycloMedia is a renowned mapping company specialised in large-scale and systematic visualisations of environments. Its headquarters are situated in The Netherlands, a country that is an excellent testing ground for continuous innovation in mobile mapping solutions. GIM International's Wim van Wegen took to the highway and headed south to the old town of Zaltbommel to talk with Frank Pauli, CEO of the developer of advanced camera and image processing techniques. You were appointed in 2013 as CEO at CycloMedia. An important part of the company’s strategy was/is the focus on the international markets. Where are we today? It certainly is part... (read more)

ESRI User Conference – A Preview

7th to 11th August, San Diego, California, US
The Annual International ESRI User Conference takes place from 7 to 11 August in San Diego, California, US. At the accompanying exhibition many companies from all over the world present products and services, often in close relationship to ESRI products. As may be expected from the location of the conference, most enterprises represented at the exhibition are US or Canada-based. But there will also be organisations from Russia, India, France, Japan and The Netherlands. The promised presence of Topcon, Thales and Leica Geosystems demonstrates the vivid and increas-ingly close coupling of GIS and surveying. This connection is also demonstrated by... (read more)

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)

Geomatics at TU Delft

Developments in Geomatics Education (6)
Collecting, processing, managing and distributing information and transforming it into relevant support for decision making constitutes the nerve system of society at local, regional, national and global scale. Of increasing importance is information bound to certain locations at, above or beneath the surface of the earth. The tools, techniques and theoretical background for acquiring, processing, managing and disseminating geo-information constitute the discipline of Geomatics. TU Delft expertise in geomatics originates from a long tradition of education in Geodesy offered over fifty years at both BSc and MSc level until 2004. Since 2005 Geomatics at TU Delft has been offered as... (read more)

Christ the Redeemer Reconstructed in 3D

UAV Deployed in Challenging Conditions to Reconstruct Iconic Statue
The famous statue of Christ the Redeemer in Rio de Janeiro has been reconstructed in 3D using a UAV. Challenging weather conditions and the sheer size of the monument meant that careful planning was required to complete the project and maintain safety. Thousands of pictures were captured around the statue and processed to create a large and accurate point cloud and a textured mesh. (By Lisa Chen and Sonja Betschart, Pix4D, and April Blaylock, Aeryon Labs) Fascinating images of the statue of Christ the Redeemer in Rio de Janeiro, Brazil, were seen around the world during last year’s FIFA World...

Benchmarking Image-based DSM Generation

The Potential for High-quality Airborne Data Collection
In view of the rapid advancement in photogrammetric technology and software for 3D reconstruction, the European Spatial Data Research Organisation (EuroSDR) initiated a benchmark project on image-based generation of Digital Surface Models (DSM). Such a comparative evaluation provides a platform for software developers to demonstrate the potential of their ongoing work. Furthermore, it can help users like National Mapping and Cadastral Agencies responsible for state-wide generation of high-quality DSMs to understand the applicability of such tools while triggering further developments based on their needs. The comparative results from 10 participants presented here provide comprehensive insight into the landscape of dense matching... (read more)
