Google Street View: Been There, Done That
On August 19, 2012, Google's Street View crew visited UNB Fredericton with a tricycle and an SUV equipped with 360-degree cameras. This event created a certain amount of excitement on campus.
Creating a street view of a city or a university campus and putting it in a geographical data base allows people to tour the city or the campus without actually being there; it's a virtual tour. When Google pioneered its Street View technology in the United States in 2007, it seemed quite remarkable. But how original was the concept? Not very, it seems. The basic idea behind Street View was investigated back in 2000 in the Department of Geodesy and Geomatics Engineering at UNB by a research team led by Prof. Y.C. Lee. The research results were presented by then graduate student Stephen Rawlinson at the annual conference of the American Society for Photogrammetry and Remote Sensing in St. Louis, Missouri, in April 2001. The results were subsequently published in the conference proceedings and then in Mr. Rawlinson's master's thesis.
The image here compares GGE's street view (called panoramas) and Google Street View, for the same intersection in downtown Fredericton.
Wondering how street view works? Click here to see a poster produced by Dr. Lee in 2001 for GGE's 40th anniversary celebrations. It concisely shows the principles involved. The background technologies were (and still are) taught in GGE's mapping and GIS (geographical information systems) courses.
Google has been very successful with its technology, one that is very similar to that developed earlier at UNB. Currently, there are 20 petabytes of data for Street View, consisting of photos taken along five million miles of roads, covering 39 countries and about 3,000 cities. Did Google get the idea for Street View from UNB? We'll probably never know.Back to the top of the page
Yun Zhang Receives the First Giuseppe Inghilleri Award
The International Society of Photogrammetry and Remote Sensing (ISPRS) has presented its Giuseppe Inghilleri Award for 2012 to GGE's Dr. Yun Zhang. The award was made at the recently held ISPRS Congress in Melbourne, Australia.
Dr. Zhang was the first person to receive the Inghilleri award, which is to be presented only once every four years to a nominee who has significantly enhanced the applications of photogrammetry, remote sensing, or spatial information sciences in the four years preceding the ISPRS congress. Dr. Zhang received the award for his important work in image fusion and automated pan-sharpening to improve the resolution of colour satellite imagery. He was recently featured in a Natural Sciences and Engineering Research Council of Canada video, "NSERC Presents 2 Minutes with Yun Zhang."
The Inghilleri award honours Giuseppe Inghilleri (1924-1982), a professor at the Politecnico di Torino, whose scientific work greatly enhanced the mathematical and statistical foundations of photogrammetry, surveying, and mapping science. The award consists of a certificate and 2,500 Swiss francs from the Italian Society for Surveying and Photogrammetry.
The ISPRS, founded in 1910 as the International Society for Photogrammetry, is a non-governmental organization devoted to the development of international cooperation for the advancement of photogrammetry and remote sensing and their applications.Back to the top of the page
A Change at the Helm
As part of the changing of the guard ceremony, Prof. Dare passed on the chairs' bottle of “medicinal alcohol” to be sampled only when facing a particularly trying circumstance that couldn't be handled in any other way. It hasn't been opened yet.
As Prof. Santos recalls the tradition: “A mysterious bottle of (deadly) buzz (Jamaican rum) has been passing from GGE chair to GGE chair for time immemorial. Nobody knows where this bottle came from, and nobody dares (no pun intended) to open it. Just a mysterious ghost sips the valuable liquid as the bottle level keeps subsiding even though it has never been opened.”
A baton was also physically as well as figuratively passed on as well. A gift from Terry Arsenault, the baseball bat will help the new chair to keep order in the house.

The Order of Canada, one of the country's highest civilian honours, was established in 1967 to recognize a lifetime of outstanding achievement, dedication to community, and service to the nation.
Dr. Masry joins GGE's Dr. John McLaughlin who was appointed to the Order of Canada in 2011.Back to the top of the page
Anna Chrzanowski Receives Life Title of Professor of Technical Sciences from Polish President
Prof. Anna Chrzanowski, D.Sc., Ph.D., P. Eng. was awarded the title of Professor of Technical Sciences by the President of the Republic of Poland, Bronisław Komorowski, at a special event in the presidential palace in Warsaw on 31 May 2012. This honour is given to a scientist only after they have achieved major accomplishments in scientific research, in university teaching, and in industrial cooperation. Not to be confused with the designation "University Professor," the title "Presidential Professor" is given for life and only after decades of scholarly work and after the recipient has obtained a doctor habilitatus (essentially a second Ph.D. degree).
Prof. Chrzanowski holds a Ph.D. degree in mining geomechanics from the Technical University of Mining and Metallurgy in Krakow, Poland, and a D.Sc. degree in geomatics from the University of Warmia and Mazuria in Olsztyn, Poland. She is also a professor in the Faculty of Geoengineering, Mining, and Geology at Wrocław University of Technology in Poland, and a professor in the post-graduate Erasmus Mundus Minerals and Environmental Programme developed by a consortium of European Union universities and coordinated by Delft Technical University in The Netherlands.
Prof. Chrzanowski is an adjunct professor in the Department of Geodesy and Geomatics Engineering at the University of New Brunswick.

GGE Visits Rothesay High School Engineering Club
On May 30th, Prof. Marcelo Santos and Jay Woodyer visited the Rothesay High School Engineering Club (RHSEC), in Rothesay, New Brunswick. The RHSEC was recently placed under the spot light when they sent a balloon to "the edge of space."
During the visit to the high school, the GGE staffers demonstrated some of the gear used by geomatics engineers, such as total stations and GPS receivers. And the students presented an overview of their own balloon launch activity showing that some of the work they had done was in the field of geomatics. "They were already doing geomatics even though they did not know it," commented Prof. Santos.
Such high school visits are an important part of GGE's outreach and recruitment effort, making students aware of an internationally acclaimed university program with great employment opportunities both in Canada and abroad.Back to the top of the page
GGE Hosts Geomatics Workshop
Back in May, the University of New Brunswick's Department of Geodesy and Geomatics Engineering hosted a three-day workshop on geomatics for participants of the International Community-University Research Alliance (ICURA) project, Managing Adaptation to Environmental Change in Coastal Communities: Canada and the Caribbean or C-Change for short.
This project involves modeling the impacts of sea level rise for four Canadian and four Caribbean communities. The Canadian sites are Charlottetown, Prince Edward Island; Isle Madame, Nova Scotia; Iqaluit, Nunavut; and Gibsons, British Columbia; while the Caribbean sites are the Trinidad spawning ground for leatherback turtles; the Belize Barrier Reef; Bequia in St. Vincent and the Grenadines; and the city of Georgetown, the capital of Guyana.
The C-Change project is led by co-directors Dr. Dan Lane at the Telfer School of Management of the University of Ottawa and Dr. Patrick Watson, Director of the Sir Arthur Lewis Institute of Social and Economic Studies at the University of the West Indies (UWI), St. Augustine, Trinidad and Tobago, with the participation of a team of over twenty co-applicants, collaborators and community partners.
The purpose of the Association of Universities and Colleges of Canada-funded workshop at UNB was to transfer the technology—specifically the Coastal Collaborative GIS or CCGIS developed by Titus Tienaah at UNB—to our Caribbean partners from UWI led by Michael Sutherland. CCGIS manages local knowledge and volunteered geographic information (VGI) to support mapping and visualization of impacts. At the workshop, Aleasha Boudreau (University of Sainte Anne) described the use of CCGIS for managing historical community data in Arichat, Nova Scotia, and Don Forbes (Natural Resources Canada) discussed modeling sea level rise. GGE grad students Patrick Adda, Matt McAdam, and Andriy Rak made presentations on LiDAR, geodetic datums, and the legal impacts of using VGI.

GGE Grad Alumnus Demonstrates New Ionosphere-Based Tsunami Tracking Technology
Led by Dr. Attila Komjathy, who received his Ph.D. from the University of New Brunswick in 1997, a team from NASA's Jet Propulsion Laboratory has demonstrated a technique that has the potential to significantly improve tsunami monitoring and warning.
The technique uses data from multiple Global Positioning System receivers on the ground to measure small perturbations in the ionosphere's electron density caused by a tsunami.
The changing sea level of a tsunami, even far from a coast, generates waves in the atmosphere that make it all the way up to the ionosphere, some 350 kilometres or so above the sea surface. Here, they disturb the electrons that affect the propagation of GPS signals. The disturbance is so small that ordinary GPS receivers do not notice the passage of the waves. However, with advanced software processing of the data collected by specialized receivers used, for example, by surveyors and geodesists, the waves can be visualized and used to track the progress of the tsunami.
The JPL team has dramatically demonstrated their technique for the devastating tsunami associated with last year's massive offshore Japanese earthquake. They used data from the more than 1,000 receivers of Japan's permanent GPS monitoring network. The propagating ionospheric waves can be clearly seen in a video the team has posted to YouTube: http://www.youtube.com/watch?v=iR6ZfG1gAms&feature=youtu.be
The video can also be downloaded from the GGE website.
An earlier report on NASA's tsunami-detection work can be found here: http://www.gpsworld.com/gnss-system/algorithms-methods/innovation-tsunami-detection-gps-4212
NASA is investing in research to obtain real-time GPS measurements from around the world so that researchers can integrate this technology into a global tsunami warning system. Additional potential applications might include the remote sensing of ionospheric perturbations generated by other natural hazards such as earthquakes and volcanic eruptions and human-made events such as nuclear tests.
Dr. Komjathy was one of the first to investigate the use of GPS signals to study the ionosphere. His pioneering Ph.D. research under Prof. Richard Langley was awarded a Governor General's Gold Medal.
Added 2012-June-12: A paper on JPL's work entitled "Ionospheric Signatures of Tohoku-Oki Tsunami of March 11, 2011: Model Comparisons Near the Epicenter" by Galvan et al. is being published by the American Geophysical Union's journal Radio Science with the digital object identifier: 10.1029/2012RS005023.

UNB Launches Atmospheric Correction Service for Space Geodesy Applications
The Department of Geodesy and Geomatics Engineering at the University of New Brunswick announces the launch of the UNB Vienna Mapping Function (UNB-VMF1) Service. This service provides geodetic-quality corrections to the signal propagation delays caused by the troposphere—the lowest-most portion of the Earth's atmosphere—that are experienced by radio-based space-geodetic techniques such as GPS, other global navigation satellite systems, and very long baseline interferometry.
Although conventional procedures exist for modeling tropospheric delays, the new service promises corrections that approach one centimeter in accuracy by mathematically tracing the path of the radio signals through numerical weather models.
The service is based on the Vienna Mapping Functions developed by the Institute of Geodesy and Geophysics at the Vienna University of Technology. While tropospheric delay corrections using the mapping functions together with data from the European Centre for Medium-Range Weather Forecasts are already available, UNB will offer an alternative service with some distinctive advantages.
The mission of the UNB-VMF1 service is to:
- Support the geodetic and other scientific communities through research providing state-of-the-art corrections to the tropospheric delay for space-geodetic techniques.
- Improve the availability of tropospheric delay products with the addition of an independent source derived from independently-acquired data and independent ray-tracing algorithms.
- Achieve greater compatibility with other derived corrections, such as those for atmospheric pressure loading, using numerical weather prediction models.
The UNB-VMF1 service utilizes state-of-the-art numerical weather model datasets from the U.S. National Centers for Environmental Prediction and the Canadian Meteorological Centre, as well as state-of-the-art ray-tracing algorithms developed by GGE researchers.
The output of the UNB-VMF1 service has been approved as a provisional product by the directing boards of the Global Geophysical Fluids Centre and its parent organization, the International Earth Rotation and Reference Systems Service. The UNB-VMF1 service now begins a mandatory two-year evaluation period with the goal of obtaining full approval in time for the meeting of the European Geosciences Union in 2014.
Further details about the UNB-VMF1 service and datasets for corrections can be obtained from the official website: unb-vmf1.gge.unb.ca.
The research associated with the UNB-VMF1 service is supported by the Natural Sciences and Engineering Research Council of Canada.Back to the top of the page

GGE's Yun Zhang Receives Research Council Award from Governor General
At a ceremomy at Rideau Hall on Monday afternoon (27 February), Prof. Yun Zhang of the University of New Brunswick's Department of Geodesy and Geomatics Engineering received one of this year's Natural Sciences and Engineering Research Council Synergy Awards for Innovation.
The Synergy Awards recognize partnerships in natural sciences and engineering research and development between universities and industry. They honour the most outstanding achievements of university-industry collaboration in the natural sciences and engineering. Winners receive a $200,000 research grant.
Prof. Zhang, who holds the Canada Research Chair in Advanced Geomatics Image Processing at UNB, received the award for his research with imagery taken by satellites. As stated in an NSERC backgrounder, "[the] satellites provide the ultimate "big picture" and make it possible to see what's happening in hard-to-reach places. However, it can be slow, expensive and difficult to process the vast amounts of data captured by satellite imagery. This team is working to solve this problem by creating complex algorithms that can fuse images from satellites with a processing speed and image quality that is the best in the world. It's also developing technology that makes remote sensing imagery look more like traditional aerial photography."
Prof. Zhang's research aims at solving challenging technical problems in remote sensing image processing that are of great benefit to industry. He has worked directly with PCI Geomatics in Toronto, a world leader in geo-imaging products and solutions, who have implemented a number of Dr. Zhang's innovations. Prof. Zhang teamed with PCI Geomatics for the NSERC award.
The awards ceremony was hosted by His Excellency the Right Honourable David Johnston, Governor General of Canada.

UNB to Help Train Europeans in Understanding Space Weather Effects on Satellite Navigation
The University of New Brunswick has become an official partner of a major European program to train the next generation of scientists and engineers to counter solar threats to satellite positioning and navigation systems.
One of the major threats to our ever-increasing dependence on GPS and other global navigation satellite systems (GNSSs) comes from the sun. Solar-related phenomena and their effect on the Earth's ionosphere, such as ionospheric scintillation, can be very disruptive, with serious consequences.
As we approach the next solar maximum in 2013, when ionospheric effects will be at their greatest, a network of internationally renowned experts, led by the Institute of Engineering Surveying and Space Geodesy (IESSG) at The University of Nottingham, are joining forces to help protect society from the effects of solar-related phenomena on GNSS signals. These experts will be training a new generation of young researchers as well as developing new research programs in the field of ionospheric perturbations and their mitigation.
At worst, solar outbursts can black out satellite signals altogether. They can also create positioning errors and rapid signal fading. These intermittent problems can impact all GNSS users including mission-critical and high-precision applications for air, rail, and marine transport, and even autonomous machinery in areas such as agriculture.
Testimony to the damaging effects of ionospheric interference were the serious service interruption and degradation caused by the so-called “Halloween storm” event that took place in October/November 2003, when one of the most intense solar flares ever was recorded: companies delayed high-precision land surveying, postponed airborne and marine surveys, cancelled drilling operations, and resorted to backup systems and commercial aircraft were unable to use GNSS-based systems for precision approaches.
TRANSMIT — Training Research and Applications Network to Support the Mitigation of Ionospheric Threats — is the first project of its kind in Europe. It is made up of a consortium of leading universities, research centres, and industry across Europe and as far afield as Brazil and Canada.
This €4m initiative is being funded by the European Commission (EC) through a Marie Curie Initial Training Network (ITN). ITNs are part of the FP7 People Programme and aim to improve the career perspectives of researchers who are in the first five years of their research career in both public and private sectors.
Marcio Aquino, coordinator and senior researcher in IESSG, said: “Europe lacks robust counter-measures to deal with these ionospheric threats. TRANSMIT will succeed in its aims because of the strong expertise and resources from its exceptional set of partners, encompassing both academic excellence and top-end users — including the aerospace and satellite communications sectors, GNSS system designers, service providers, major user operators and receiver manufacturers. The EC investment in projects like this confirms the importance Europe is giving to this new and exciting research area.”
The project will place Europe in a position to compete with state-of-the-art technology already being developed in North America.
A number of TRANSMIT fellows, the students selected to participate in the training program, will visit UNB for short periods to learn about the space weather data analysis tools and techniques developed by researchers in the Department of Geodesy and Geomatics Engineering and the Department of Physics on the Fredericton campus.Back to the top of the page
