Remote sensing / Earth observation specialist working for Teagasc
Stuart Green - Earth observation specialist
What were the main “career decision” milestones in your life so far?
As a primary degree I studied geophysics, graduating in 1992. I had given little thought to further study, but an economic downturn made me reconsider.
The Erasmus programme was offering excellent bursaries to study for an MSc in remote sensing in Dundee University, and without doubt this was the major career milestone.
It not only introduced me to my area of work but the programme also allowed for travel within the EU, which was how I came to study in UCD for the second half of my Masters.
After the MSc I decided to stay in Ireland and was offered a technician post in the lab where I had completed my MSC, the applied physics lab in UCD under Eoin O’Mongain.
After a couple of years on rolling short-term contracts, an opportunity for a PhD came up in the lab, which I took.
Describe a typical day
At any time I may have four or five projects “live” – some instigated and led by me (for instance a creating a map of hedgerows for the whole country), some where I’m a partner (using airborne lasers, LIDAR, to measure forests) and others where I am merely providing information or input (mapping farmland habitats).
It’s best to concentrate on one project in a day, but phone calls, emails, reports etc can quickly take over if you are not careful. But you can always switch to another if you get stuck, deadline permitting!
What are the main tasks and responsibilities?
My main task is to research the use of remote sensing and Earth observation technologies in agriculture in Ireland. Most work is based on the computer with a little field work.
What particular skills do you bring to your workplace?
As in most scientific enterprises, you need to combine good technical skills with curiosity and ingenuity. I think I’m good at problem solving: coming up with elegant and not so elegant solutions to issues.
What subjects did you take in school and how have these influenced your career path?
I took a wide range of subjects at secondary school: physics, chemistry and maths but also English, history, classical studies (ancient Rome and Greece) and art.
What is your education to date?
- A-level maths, physics and chemistry
- BSc in Geophysics
- MSc in remote sensing
What aspects of your education have proven most important for your job?
Undoubtedly maths is very important in this type of science career. It carries through to many different areas.
What have been the most rewarding events in your career so far?
For my PhD I flew all over Ireland in a single-engine Cessna.
Working in the lab I took part in research cruises in the Aegean and working for Teagasc I helped create the National Indicative Soil Map. This is now used as a fundamental dataset by literally hundreds of researchers, engineers and government agencies.
What advice would you give someone considering this job?
Be willing to learn on the job. Remote sensing can only be really successful when the researcher understands the system and the physics but also understands something of the target.
So even though my background and training is in “physics” I’ve had to pick up lots of information on forestry, ecology, soil science and others.
What are the three most important personal characteristics required for the job?
Curiosity, adaptability and a good “spatial awareness” – you need to get used seeing unusual things in unusual contexts!
What kinds of work experience would provide a good background for this position?
Computer labs, design studios and digital media will all give a sense of handing and using images on a computer. Architects and civil engineering firms will give an idea on maps and spatial awareness. Try using Google Earth for a specific goal, such as introducing Google Earth and Google Maps into a community organisation or charity.
