IFHS Student Award winners for 2018 and 2019 announced
Last month, in the run-up to World Hydrography Day (WHD) 2019, the International Federation of Hydrographic Societies (IFHS) announced the winners of its prestigious Student Award for 2018 and 2019.
Newly appointed Chairman, Eric Langlois, presented Hamza Mazih and Christopher Haddon with their £1,500 (GBP) prizes and commemorative certificates at an evening ceremony in Marseille, France, on Monday 17th June.
Hamza, who was nominated by the Francophone Hydrographic Society (AFHy), won the 2018 award for his paper entitled Implementation of a protocol for acquisition and processing of strapdown gravity data from airborne inertial navigation system to compute geoid models in coastal areas. Hamza, who graduated the MSc Hydrography at ENSTA Bretagne in France last autumn, is now employed by Fugro.
Christopher's 2019 award-winning paper provided Insights into embayment-scale sediment dynamics using MBES multispectral backscatter at Perranporth, UK. Nominated by The Hydrographic Society UK, Chris received the honour just days after completing his BSc (Hons) Ocean Exploration & Surveying at the University of Plymouth, UK. He is due to start work with MMT in the coming weeks.
Earlier the same day, Hamza and Chris both presented their research work to an international audience attending an IFHS one-day hydrography workshop, which formed part of the world-renowned Oceans 19 conference in Marseille. The workshop programme also addressed topical matters such as survey standards, crowdsourced bathymetry, data rescue, capacity building, hydrographic education and individual certification.
IHO Conference April 2020
Dear corporate member,
An IHO conference will be held in Monaco from 21-24 April 2020, including delegations from all Member States and observers from various neighboring organizations.
In the conference building, the industry is given the opportunity to present itself with a stand.
For more details, I refer you to the appendix of the International Hydrographic Organization (IHO): IHO Exhibitor Info
Invitation: SIKB Annual Congress 2019
+31 Just call the Netherlands ......, that is the theme for the SIKB annual conference 2019. Under the leadership of SIKB board member Jeroen Haan, by that time dyke count of the Hoogheemraadschap De Stichtse Rijnlanden, the knowledge and expertise of Dutch soil and subsurface management and archeology, in an (inter) national context. What can we learn from our approach elsewhere in the world, and what can we learn from elsewhere? The ambition is there:
"+31 - Call the Netherlands". With speakers such as Marck Haerkens who offers inspiration from aviation and Ad van Wijk who takes a look at the (underground) energy landscape in 2031. With debates between, for example, professor John van den Hof and professor Daan Raemaekers about the knowledge and competences that the soil and archeology professionals are asked. With sixteen different parallel sessions. With a Blunder- and Glunderbak and a closing drink at the SIKBar: what is your vision for 2031?
Click here for the program booklet with more information about the conference and the sharing sessions. You can sign up here.
We look forward to meeting you on Thursday 26 September in the 1931 convention center in 's-Hertogenbosch.
Workshop "GNSS for new precision applications"
On Friday, June 14, 2019, the GNSS Symposium for new precision applications was organized at the Technical University in Delft. Around 110 interested people attended the event organized by the Netherlands Institute for Navigation (NIN), Geo-Information Netherlands (GIN) and the Hydrographic Society Benelux (HSB).
Almost everything one does is location related and GNSS help us to determine where that is. Precision and reliability are increasingly required. New hardware and software developments for mass markets make more and more possible in this: small and affordable, yet also advanced GNSS chips and antennas, which offer almost the same observations and quality as geodetic GNSS receivers, make a massive deployment for new applications possible. Seven speakers from different disciplines discussed this during the symposium.
Small is beautiful
Chris Lowet, Product Manager at Septentrio NV in Leuven, Belgium, spoke first about the newly developed GNSS module for mass applications, called "Mosaic". Despite its small size (3x3 cm) and low power consumption, this module can use all available GNSS signals and arrive at a centimeter-accurate position determination. The "Mosaic" can be used in, among other things, self-driving robots and cars, drones and agricultural machines. The module distinguishes itself on the market by working well even with many obstacles and the anti-interference and jamming technology that Septentrio is known for.
New player on the RTK market
The second speaker, Tommy van der Heijden, founder of MarXact, presented the UNI-GR1 universal RTK GNSS receiver. This receiver is assembled in the Netherlands and supports all modern GNSS signals. The GNSS board comes from the Chinese supplier Unicore. With the help of UNI-Cloud, UNI-RTK premium and various APIs, this is a ready-made, open receiver that communicates with many software packages.
Automatic and affordable geo-monitoring
Jürgen Alberding, director of Alberding GmbH from Wildau in Germany, took the audience to the new world of automated geo-monitoring. Alberding offers tailor-made services for deformation measurements of, among other things, soil and engineering structures. Components include Web-based server software and integrated GNSS and telemetry sensors. The GNSS sensors are low-cost modules that can collect both code and phase observations.
"Crowd Sourced Bathymetry"
After the coffee break, Chief of Hydrography and Captain of the Sea Marc van der Donck of the Ministry of Defense picked up the thread firmly. He showed those present that the seabed is clearly the worst part of the earth. It is striking that this applies especially to the shallower areas at sea. Under the slogan "Map the Gaps" a campaign has been launched to close the gaps in the sea charts. By collaborating and sharing data from many other parties who perform depth measurements at sea, such as survey companies, fishing vessels and cruise ships, the aim is to speed up the measurement process.
Customized GNSS in developing countries
The fifth speaker, Ernst Peter Oosterbroek, Senior Land Administration Advisor at Kadaster International, spoke about the need for good land registration in poor countries. Security of ownership is a basic condition for a growing economy. In various countries in Africa, South America and Asia, Kadaster International helps with projects for acquisition and registration of property. A combination of aerial photos and affordable GNSS makes this possible.
Farmers measure Water
A completely different deployment of new GNSS was proposed by Jouke Velstra, director of Acacia Water BV, in Gouda. Together with LTO Noord, water boards, provinces and farmers, Acacia Water strives to realize a joint monitoring network for surface water and groundwater and soil water.
Salinisation along the coast is, partly due to subsidence, rising sea levels and periods of major drought, an increasing problem in agriculture. Farmers and water boards should work together in this and an extensive monitoring network is essential for making the right decisions.
Use of GNSS in Drones
Finally, Pieter Franken from Terradrone Europe (formerly Skeye BV) gave a presentation about the importance of GNSS in the worldwide deployment of drones for measurements and inspections. Applications of GNSS range from the automatic flying of flight patterns, measuring of pass and check points, precise location of recordings to the replacement of expensive IMU equipment (inertial navigation). Pieter emphasized that only a combination of technology and geodetic knowledge leads to reliable results.
After the symposium, all speakers were thanked with a Delft blue storm umbrella developed at TU Delft and they were able to talk afterwards during a drink offered by the associations.
The symposium was organized on behalf of the VPN GIN / NIN Working Group by:
Sandra Verhagen, TU Delft ; Hans Visser, Fugro ; Lennard Huisman, GRC / Geopinie ;
Jean-Paul Henry, 06-GPS
