Welcome shall they be,
And all the honours that can fly from us
Shall on them settle. You know your places well;
When better fall, for your avails they fell
To-morrow to the field

International Cooperation Agreement Signed between East China Normal University and UNB

When Prof. Liu Shuren, East China Normal University (ECNU), Shanghai, visited the department in August 2000 (see previous story), a draft proposal for international cooperation was drawn up between UNB and ECNU. In November, President Liz Parr-Johnston was in Shanghai and signed the agreement as established in August. ECNU specializes in education and the geosciences for which it is recognized as one of the best universities in China. In the area of the geosciences, ECNU has strong nation-wide research institutes that specialize in ocean mapping, geographic information systems, and remote sensing. GGE's Dr. Yun Zhang, who helped propose the international cooperation, will be working with Prof. Liu in the area of remote sensing. They plan to initiate joint research into applications of the new commercial high-resolution satellite imagery to investigate precision change detection of urban environments, first in Fredericton and then in Shanghai.

International GIS Day at Fredericton High School

On 15 November 2000, Drs. Sue Nichols and David Coleman participated in the International GIS Day seminar organized by CARIS/Universal Systems Inc. at Fredericton High School. With over 60 students in attendance from Grades 10 to 12, Dr. Coleman led off with a brief introduction to the wide range of applications of geodesy and geomatics in today's society. Dr. Nichols then followed with a discussion of how geomatics addresses particular problems in environmental monitoring and land management. Good discussions followed with the students and teachers present. This is the second year that UNB GGE faculty and staff have worked with CARIS/Universal on GIS Day presentations.

Dave Wells, André Godin Recipients of U.S. Navy Superior Public Service Awards

On 30 October 2000, David Wells (who teaches hydrography at UNB, The University of Southern Mississippi, the University of New Hampshire, and the Universiti Teknologi Malaysia) and André Godin (M.Eng. 1997, on leave from the Canadian Hydrographic Service, Laurentian Region) were presented with Superior Public Service Awards by Rear Admiral Ken Barbor, Commander, Naval Meteorology and Oceanographic Command, United States Navy. The award is comprised of a large medal, a smaller medal to wear on the lapel (or navy uniform), a lapel bar, a Certificate of Award, and a citation.

It is rare that the U.S. Navy awards such medals to civilians, but it is rarer still for non-Americans to receive such an honour. As can be seen in the last sentence of the citation, it appears that there is some confusion about which country Dave and André are serving. The reality, however, is that such an award has never been made to non-Americans, and the wording of that final sentence, by law, could not be changed.

Attending the ceremony in honor of the recipients were Larry Mayer, Dave Monahan, Rob Hare, Lee Alexander, Sam DeBow, Jim Gardner, Mike Harris, and some 30 other guests. "In a fundamental way," says Dave Wells, "it validated the educational and research principles and practice of the UNB Department of Geodesy and Geomatics Engineering, and acknowledges that the new University of Southern Mississippi program would likely not exist without the UNB model to draw upon."

Our congratulations to both Dave and André.

Welcome Back Block Party a Success

On 12 September 2000 the First Annual GGE Block Party was held to welcome both new and returning students to GGE. The main hallway outside the Department was closed off between 12 noon and 2:00 p.m., pizzas and pop were brought in, and a lively time was had by all. The turnout was impressive, and the staff and the professors were able to meet the new students and discover where they were from and what their goals were. It was also an opportunity for graduate students and senior undergraduates to mingle with those following in their footsteps and to advise them that GGE was the best department with the most impressive employment record on campus.

We plan to make this an annual event, and next time our digital camera will be available to provide better pictures of the festivities.

GGE one of the Sponsors for Digital Earth 2001 Symposium

In June 2001, the geomatics world will turn its attention to Fredericton, New Brunswick, for an international symposium on one of the most exciting frontiers in science and technology. The Second International Symposium on Digital Earth, Digital Earth 2001, will be one of the largest scientific symposiums ever to take place in Atlantic Canada, with more than 800 scientists, researchers, academics, government officials, and business leaders from around the globe expected to attend.

With UNB's Department of Geodesy and Geomatics Engineering as one of the sponsors, the Canadian Institute of Geomatics and the Greater Fredericton Economic Development Commission will be co-hosting the symposium at the Sheraton Hotel in Fredericton from 24-28 June 2001.

Under the theme "DIGITAL EARTH 2001: Beyond Information Infrastructure," this symposium has combined the organization and attraction of four separate conferences - normally held separately - into one integrated event:

The first symposium on Digital Earth was held in Beijing, China, in December 1999. The 2001 symposium's theme - "Beyond Information Infrastructure" - was chosen to encourage presenters to describe applications, technologies, and activities, now under development or in the planning stages, which will reflect a world where the geospatial data infrastructure is already in place.

Full information on the symposium, including a call for papers, may be found at the symposium web site.

The symposium will cap off a busy 7-10 days of meetings, presentations, and social events at the end of June:

GGE Department faculty, staff, and graduate students are already involved in the planning and organizing of all these events. We are looking forward to seeing friends and colleagues next year. BOOK YOUR TRANSPORTATION AND HOTEL ARRANGEMENTS EARLY. Late June is usually a wonderful time of year in Fredericton, we expect a good crowd for these events, and both airline seats and accommodations will be in high demand at that time of year.

Watch the GGE Web pages for more information about all three events.

John Hughes Clarke Down Under for RAN Sea Trials

John Hughes Clarke spent the last week in August 2000, completing sonar performance trials for the first of the new Australian Navy Hydrographic Survey Ships, HMAS Leeuwin (A245). She is the first of a pair of new survey vessels to be delivered to the Royal Australian Navy (RAN). HMAS Leeuwin and her identical sister ship, HMAS Melville, are 71 m vessels that operate an ATLAS Fansweep 20-100 multibeam sonar in support of hydrographic survey operations in tropical waters. In the near future, they will take on three survey motor boats, each equipped with Fansweep 20-100s.

John was asked by the RAN to conduct a performance evaluation of the Fansweep sonars in order to assess their accuracy, target detection, and sidescan imaging capability. This involved a six-day operation in the northern Great Barrier Reef between Endeavour and Agincourt Reefs. A report on the conduct of these trials will be released to the RAN in the next few weeks.

Educational Alliance has First Meeting

On 11 and 12 July 2000, the first meeting of the tentatively named North American Hydrographic and Ocean Mapping Educational Alliance (NAHOMEA) met in Durham, Hew Hampshire. Attending the meeting were representatives of three universities, two government agencies, and a private enterpriser. The "alliance" among the University of New Brunswick (UNB), the University of New Hampshire (UNH), the University of Southern Mississippi (USM), the Canadian Hydrographic Service (CHS), the U.S. National Oceanographic and Atmospheric Administration (NOAA), and C&C Technologies (C&C) met to discuss ways in which the three university ocean mapping and hydrography programs could benefit from future co-operation. From this meeting, a number of initiatives were identified, including student and professor exchanges, development of course materials, and a series of roving seminars. Also under consideration were the comments made by Jimmy Chance on what C&C Technologies would like to see in terms of improved learning objectives for our graduates, and continuing education opportunities for their employees.

At the same time, Dave Wells was able to present Larry Mayer with a wall hanging (created by Dave's wife, Solveig Wells) for Larry's new offices in UNH.

Mapping Beneath the Reversing Falls

Canada's Reversing Falls, at Saint John, New Brunswick, are one of nature's more spectacular phenomena. Here the massive tides of the Bay of Fundy battle the enormous outflow of the St. John River. Unlike most estuaries, where the river and ocean mix gradually, a massive rock outcrop restricts and focuses the exchange of water. So intense is the exchange that, for the lower half of the tidal range, the gorge is a waterfall flowing into the sea. Toward the top of the tide, however, the sea level rises above the river level and the falls reverse. Only for two periods of about 10 minutes on every tidal cycle is there a brief moment of standing water at the falls, during which vessels may transit, in this case to conduct an underwater survey.

Stockholm Challenge Prize Nomination for Rima Ammouri

Rima Ammouri (Ph.D. candidate under the supervision of John McLaughlin) and the City of Fredericton have prepared an interactive Web site for the Residential Town Plat Secondary Plan. The site will include all potential changes to the area inside the city limits, including residential and commercial sites, as well as future plans for the former railway land in the city.

The Web site has been developed by Rima as a part of the research for her Ph.D. dissertation. The interactive Web page enables taxpayers to voice their concerns and residents and even non-resident property owners will have 24 hour access to the town plat. City Council is bound by law, under the Provincial Community Planning Act, to hold hearings and consultations with its citizens. With the Web site, interested parties will now have access to all plans, and City Council will be made more aware of the concerns of taxpayers.

This is Fredericton's first foray into an interactive planning process, and the project has earned a nomination in the public services and democracy category of the Stockholm Challenge: An international showcase for information-technology-spawned improvements to living conditions and strengthened communities. The King of Sweden handed out trophies to the winners on 5 June 2000 in Stockholm.

GGE Students Learn by Doing

Our second year GGE 2013 survey camp took on a different and more diverse perspective this year. The students combined their efforts with the GGE 5083 Hydrographic Surveying Operations camp to assist in providing shore control for the hydrographic survey being conducted in the mouth of the Kennebecasis River (a.k.a. Grand Bay). They were also responsible for some smaller projects (topographic surveys, control verification) on the UNB Saint John campus (UNBSJ), and finally participated in a construction survey at Canadian Forces Base Gagetown - the largest military base in the Commonwealth.

Hydrographic Survey of Grand Bay. The hydrographic operations were centred around the Royal Kennebecasis Yacht Club (RKYC) located approximately 4 km from the UNBSJ campus. The students established a base of operations at UNBSJ utilizing their facilities and the Sir James Dunn residence for much needed rest. The establishment of shore control comprised several different projects and a brief description of each is given here.

  1. Running a high precision level loop to transfer the elevation from a local geodetic benchmark to a tide gauge set at the RKYC. To meet the specifications of an official Canadian Hydrographic Service (CHS) level transfer, the students employed the 3-wire levelling technique. The CHS minimum acceptable misclosure is 0.006 m, which, considering the students had to run an approximately 4 km loop, proved to be quite a challenge. Both student groups carrying out the survey, however, got it right the first time.
  2. Establishing two permanent base monuments for GPS RTK navigation. This was done by measuring baselines from a New Brunswick high precision GPS control point located at Millidgeville High School to a point on top of Ganong Hall on the UNBSJ campus using Trimble 4700 receivers and Trimble Geomatics Office software.
  3. Identifying and measuring ground control points for orthophoto rectification. To provide an overview plan of the survey area, the students needed to collect some ground control points for the orthophoto rectification process. They first identified points on the aerial photos and then utilizing the Trimble 4700 GPS RTK system to record the positions. The actual rectification process was done at UNB Fredericton utilizing CARIS GIS software.
  4. Establishing and surveying a water boundary at the RKYC. This proved to be an interesting experience. The water conditions in early May are challenging to say the least; flood conditions and tidal ranges made all aspects of this survey difficult. First, determining the high water mark, which changed virtually from hour to hour depending on flood, rain, and tidal conditions, was almost impossible. Second, conducting the physical survey was further complicated by access problems because of flood condition. All involved learned valuable lessons.

Other Projects

UNBSJ. Consultations with Dr. James Christie and Cedric Boone (UNBSJ Dept. of Engineering) resulted in the opportunity to perform several other types of surveys. The department required a topographic survey of several locations on campus and there was concern over the validity of one of their control monuments. A brief description of each of the surveys follows. CFB Gagetown. The existing exercise complex at CFB Gagetown was in the process of expansion, and with the help of Robert Stuart, GIS administrator for the base, we were allowed access. At this point, the project was in the steel erection phase, which provided the opportunity to view the foundation and steel placement. The students were provided with a set of design drawings and were asked to mirror the foundation layout in a field across the street. This was an excellent situation since they were able to view the real thing while it was still visible to see if their efforts matched the actual construction.

2000 Angus Hamilton Lecture

This year's Angus Hamilton Lecture took place on 8 May with guest speaker Karen Siderelis, who is the Director of the Center for Geographic Information and Analysis, Office of the Governor, North Carolina. This lecture series was inaugurated by the New Brunswick Land Information Council and the Geomatics Atlantic Trust Fund in honour of Angus Hamilton, Professor Emeritus, of our department. This year's lecture was supported by the Council of Maritime Premiers, the Geomatics Association of Nova Scotia, the Canadian Institute of Geomatics, and Geodesy and Geomatics Engineering.

Karen Siderelis's presentation was entitled: "What good is an information highway when a hurricane strikes and the road is closed?" She based the question on the devastation that Hurricane Floyd did to North Carolina in the fall of 1999. Floyd, the third in a series of major hurricanes to hit the east coast of the United States recently, forced the largest peacetime evacuation in history as some 2.6 million people had to flee their homes. The North Carolina Center for Geographic Information and Analysis provided ongoing support to emergency measures, disaster relief, law enforcement, and financial compensation organizations across the state and beyond. Both the use and limitations of geographic information systems technology and data for disaster assessment and hazard mitigation planning were severely tested.

Visiting French Student Develops GPS-based Vehicle Tracking System

Geoffroy Mery de Montigny, a final-year undergraduate student at the École Supérieure des Géomètres et Topographes in Le Mans, France, carried out his "Travail de Fin d'Études" at UNB's Department of Geodesy and Geomatics Engineering last year.

For his "travail" (a practicum or practical workterm experience), Mr. de Montigny developed a real-time vehicle tracking system. Unlike commercially-available systems costing thousands of dollars, Mr. de Montigny's system was put together using "off-the-shelf" components already available in the department and used for other purposes including software developed primarily for amateur radio operators.

Mr. de Montigny carried out his work in Prof. Richard Langley's satellite navigation and positioning group, well known for its research in aircraft navigation.

The heart of the vehicle tracking system is a Navstar Global Positioning System (GPS) receiver. The GPS receiver, which is mounted in the vehicle, is coupled to a very-high-frequency (VHF) transmitter, basically a taxi radio, that sends packets of digitally-encoded position reports from the GPS unit to a VHF receiver at UNB. The receiver passes on the reports to a personal computer which displays the position of the vehicle on a geo-coded detailed map of Fredericton. The position reports are accurate to about 100 metres. While this accuracy is sufficient for many tracking purposes, the accuracy can be enhanced to the few-metre level by using differential correction data from a Canadian Coast Guard transmitter in Saint John. Both the vehicle's current position and where it has been can be displayed.

Mr. de Montigny's system has the capacity to track not just one vehicle but whole fleets of vehicles such as police cars, ambulances, delivery trucks, or taxis. Although the prototype system was limited to line-of-sight distances from UNB's Gillin Hall engineering building, the tracking range could be extended using repeater stations, cellular telephone links, or satellite relays.

Dr. Santos will be teaching geodesy, applied analysis, and imaging and mapping, and continuing his research on various topics related to the Global Positioning System.

In February 2000, Dr. Yun Zhang joined the Department as an Assistant Professor, to teach imaging and mapping. Dr. Zhang joins us from The University of Calgary where he was a Post-Doctoral Fellow. Yun received his Ph.D. in photogrammetry and cartography in 1997 from the Berlin Free University, and has gained industrial experience with the Institute of Planetary Exploration of the German Aerospace Center. He will be continuing his research in the areas of remote sensing, and digital photogrammetry and image processing.

Prof. Langley in the News

Richard B. Langley (Professor of Geodesy and Precision Navigation) has appeared a couple of times recently in the print medium. In November, he was quoted extensively in an article by Karen Joan Watson, entitled "Global Positioning Systems, Dick Tracy, Call Home!" published in Forum, Canada's National Municipal Affairs Magazine. In the article, Watson recalls that it was the Department's satellite navigation experts who predicted in 1983 that a GPS-type receiver the size of a wristwatch would be available in the twenty-first century. Technology advances more rapidly than we often imagine and, thanks to Casio who brought out a $750 GPS wristwatch receiver in 1999, the prediction came true before the twenty-first century began.

Prof. Langley has also appeared in the December issue of UNB's Perspectives. A press release detailed the work being done by researchers in the Department to enhance GPS in aircraft navigation.

Prof. Langley continues to produce the acclaimed "Innovation" column each month in GPS World magazine - a charge he has carried out ever since the magazine was first issued in January 1990.

Message from the Department Chair: A Sea Change

On 1 January 2000, Prof. John Hughes Clarke assumed the role of Chair in Ocean Mapping and Director of the Ocean Mapping Group, and became an associate professor at UNB. With over 15 years of experience here and at Dalhousie University, Bedford Institute of Oceanography, and James Cook University, Australia, Dr. Hughes Clarke led the UNB team called in to locate the debris field of Swissair Flight 111 in the fall of 1998. An oceanographer and member of the Ocean Mapping Group at UNB since 1991, John's research interests focus on improving swath bathymetry and acoustic imaging systems to better investigate the ocean floor. We look forward to the closer involvement of John in the Department's regular doings.

Also beginning in January, Prof. Larry Mayer assumed the directorship of the University of New Hampshire's new Center for Coastal and Ocean Mapping in Durham, New Hampshire. He has been joined there by Dr. Colin Ware, a former member of the Ocean Mapping Group and of UNB's Faculty of Computer Science; a team of researchers from Heriott Watt University in Scotland; a contingent of NOAA officers and scientists on assignment there; as well as a number of former UNB graduate students (Semme Dijkstra, Hou Tianhang).

Larry became the ocean mapping chairholder in 1990, and his friendliness, energy, high standards, and marvellous sense of humour contributed greatly to the success of the Ocean Mapping Group. They will doubtless serve him well during his one-year leave of absence as he works to establish the New Hampshire Center and bring it to a level of funding and resources similar to those enjoyed by the Ocean Mapping Group at UNB. He will work towards forging a strong partnership between the two groups. To this end, it is expected that some UNB faculty will be named to adjunct positions at the University of New Hampshire.

Prof. David Wells, the former Ocean Mapping Group director and recently retired from UNB, is also taking on a new part-time assignment. With the help of the U.S. Navy, he has been asked to develop a new ocean mapping program at the University of Southern Mississippi, at Stennis Space Center. Dave will stay on in his role as Professor Emeritus at UNB and continue his work here during the summer and fall months. Come winter, however, he will turn snowbird and reside in Mississippi. (See the following story for more details.)

We are sorry to see Larry leave, but we welcome John and wish both John and Larry the best of luck in their new positions. Click on the thumbnail image to look at pictures taken during a small farewell and transfer-of-power gathering that was held in the Department, 130 KB.

David Wells Bound for the "Playground of the South"

Gulf Coast, magnolias, mansions, beaches, sun, sand, and surf. These words could describe David's next few months, but to be more realistic, his sojourn at the University of Southern Mississippi will probably entail teaching, training, listening, learning, and 24-hour work days. From January to May 2000, David will be fulfilling a subcontract with The University of Southern Mississippi's Department of Marine Science on NASA's John C. Stennis Space Center, near Bay St. Louis, 70 km east of New Orleans. This department specializes in graduate studies and research dealing with the many aspects of marine and aquatic environments. David's particular contributions will be two courses, one in applied bathymetry and the other in satellite geodesy and positioning.

Aside from teaching these two courses, David will also be giving advice on strengthening the new curriculum to the Hydrographic Science Program Coordinator, his immediate supervisor, who is André Godin (M.Eng., 1997 under the supervison of D. Wells!), and to the project director and chair of the department of marine science, Dr. Denis Wiesenburg. David would like to title this story, "Professor Emeritus Works for Former Graduate Student."

What David finds most exciting about the positive outreach of his southern venture (other than escaping the Fredericton winter) is that our program at UNB will benefit from the links being established with The University of Southern Mississippi (USM). David will be gaining insight from the extensive sea experience of USM students, all U. S. Naval Oceanographic Office employees and officers. The possibility of combining the UNB and USM practical field experiences could be of great benefit to the students from both universities.

We wish David well in this endeavour, and expect him to return in May full of new ideas and enthusiasms.
