GNSS Positioning

Status and Features
Nowadays, GNSS receivers have scores – and often hundreds – of channels, enabling them to track GPS, Glonass, Galileo and Compass signals simultaneously. The whole workflow from satellite tracking to calculating the coordinates of the position in a preferred reference system can be conducted automatically in real time. The price of GNSS receivers has dropped steadily since the first GPS receivers came onto the commercial market in 1982. In conjunction with the latest product survey results for GNSS receivers (available at www.geo‑, the author puts today’s GNSS status and features in perspective.

A Visit to...Hewlett Packard Barcelona

Hewlett Packard (HP) celebrates the twentieth anniversary of its Barcelona site this year. The company has a portfolio spanning printing, personal computing, software, services and IT infrastructure, and Barcelona is the nerve centre of its predominant large-format printing activities. On 3rdand 4thApril 2008 the international professional press was invited to look ‘Behind the Scenes’.<P>   "Our workforce in Barcelona consists of more than two thousand people, including employees working in our engineering and support facilities," Francois Martin introduces us to the facility. Since 2006 he has been marketing director for Graphic Arts. As might be expected, nearly 75% of the... (read more)

Smart Factories Need Space and Time Anchors

Enhanced SDI-based Human-machine Interaction
Spatiotemporal referencing can be used to enhance contextualisation of Industrial Internet of Things (IIoT) data and information flows within ‘smart’ factories, according to Studio iSPACE in Austria. Its five-step approach models an adaptive workflow to organise large-scale 3D data of a production facility. The goal is to support the extended personnel-machine interaction for indoor positioning, production asset monitoring and location-based management. In the event of problems with a production line, every minute counts for the factory’s managers. Service staff must be able to respond as efficiently as possible. All necessary information should be directly available and location-based. Studio iSPACE, part... (read more)

Towards Automated Detection of Visual Cadastral Boundaries

Initial Investigations of Imagery, Algorithms and Perceptions
The technology push behind emerging automated feature identification and line generation techniques provides a new opportunity for the domain of fit-for-purpose land administration. It could help to further automate the process of boundary generation in cadastral systems – particularly in contexts where large areas remain unmapped and cadastral boundaries align with topographic or visual boundaries. (By Yismaw Abera Wassie, Mila N. Koeva and Rohan M. Bennett) Fit-for-purpose land administration aims to align cadastral policies, administration and technology selection with the prevailing societal needs and capacity within a country context. It seeks to aid delivery of more rapid and low-cost cadastral boundary... (read more)

ASPRS Honorary Members Selected

Clifford W. Greve and Vincent V. Salomonson have been selected as the next Honorary Members of the American Society for Photogrammetry and Remote Sensing (ASPRS). Their nominations were recently approved by the ASPRS Board of Directors. This is the highest award bestowed by ASPRS and there can be only 25 living Honorary Members of the Society at any given time. Initiated in 1937, this lifetime award is given for professional excellence in recognition of individuals who have rendered distinguished service to ASPRS and/or who have attained distinction in advancing the science and use of the geospatial information sciences. Greve and... (read more)

Preserving Technological Monuments in Russia

Terrestrial Laser Scanning of the Aurora Cruiser and the ‘Motherland Calls’ Statue
Technological monuments are vulnerable to decay. 3D modelling and documentation are essential to avoid them falling into irreparable decline and to enable future restoration. Terrestrial laser scanning (TLS) is a proven technology for capturing complex objects. Read about the TLS capture of two iconic technological monuments in Russia: the Motherland Calls statue and the Aurora cruiser. . (By Andrey Leonov and Mikhail Anikushkin, Russia) Technological monuments are more vulnerable to decline than paintings or manuscripts, since they are located outdoors and exposed to rain, temperature variations and other weather elements. They also often suffer from overdue maintenance due to a... (read more)

Three Shows in a Row

The cusp carrying winter into spring saw three interesting geomatics shows across the USA from east to west. Tom Gibson, editor-in-chief of our US sister magazine, Professional Surveyor, visited one after the other and sent us this report.<P>   The Annual Conference and Technology Exhibition of American Congress on Surveying and Mapping (ACSM) took place at Spokane Convention Center in Washington, attended by about 1,550 people, up slightly on last year. More Work As usual the conference featured a slew of workshops. Gavin Schrock discussed GPS Communications by network transportation of RTCM via internet protocol (NTRIP). NTRIP is the most...

Using Geospatial Acoustics to Track Bat Movements

Infrastructure plays a significant role in disrupting the flight paths of bats. Traditional methods of monitoring bat movements are rather limited and often prone to error. Using acoustics, GIS and 3D simulation engines, the Bat3Data system enables the field ecologist to differentiate between species and trace their flight paths in 3D along existing and proposed infrastructure. This helps to gauge the efficiency of gantries, bat bridges and underpasses in helping bats to cross roads and railway lines. The system can help to improve the remediation of ecological corridors affected by infrastructure. (By Vivian Raiborde, Frédéric Jehan and Hippolyte Pouchelle) With... (read more)

Mobile Mapping Trends and Insights

Data Analysis by Geomares
Mobile mapping technology is on the rise worldwide. Industry specialist Geomares – publisher of 'GIM International' among other things – has analysed the user data and behaviour of thousands of members of the global geospatial community. This article presents the findings from that analysis, identifying the latest trends and sharing insights into the future outlook for mobile mapping. Recent advances in mobile mapping technology are enabling new capabilities and complementing – or even replacing – traditional survey methods of topographical surveying. Futhermore, widespread investment in city planning and ‘smart city’ projects is expected to further accelerate the adoption of mobile... (read more)

Protecting Location Privacy Brings Opportunities to the Geosector

Since members of the geosector are well versed in potential applications of geoinformation and its fusion with other data sources, they are best equipped to devise and test technology-based solutions for location privacy-related challenges. That is the opinion of Dara Seidl, a young expert on geoprivacy, who won the first pan-American master’s thesis contest on geoinformation. (By Frédérique Coumans, contributing editor) Dara Seidl was selected by a jury of worldwide experts as the winner of the ‘Prize for the Outstanding Master’s Thesis in Cartography, Geodesy and Geo-Information 2015’ for her thesis titled ‘Striking the Balance: Privacy and Spatial Pattern Preservation...
