How Distant Sensing Applied sciences Enhance Meals Manufacturing

However her engineering path finally led her again to agriculture. She has developed distant sensing applied sciences that, amongst different makes use of, map crops extra precisely, improve crop yields, and enhance administration practices whereas lowering the time it takes to pick out promising new hybrids.

Crawford is a professor of civil engineering, agronomy, and electrical and laptop engineering at Purdue College, in West Lafayette, Ind. In agronomy, she collaborates with researchers in plant genetics, plant physiology, agrometeorology, and soil science. In engineering, she focuses on growing strategies to research distant sensing information.

For her “contributions to distant sensing expertise and management in its software for the good thing about humanity,” the IEEE Fellow is the recipient of this 12 months’s IEEE Mildred Dresselhaus Medal. The award is sponsored by Google.

An early environmental activist

As a teen within the Sixties, Crawford was drawn to the U.S. area program; she initially aimed for a profession within the aerospace trade.

“Area was actually inspiring in these days,” she says. “I didn’t wish to be an astronaut, as a result of I’m claustrophobic. I used to be within the design and operation of airplanes and spacecraft.”

However throughout her time as a freshman on the College of Illinois in Urbana-Champaign, the aerospace trade went by a interval of mass layoffs. She realized that aerospace was a boom-and-bust trade, she says.

In the meantime, she says, environmental points have been gaining consideration because the influence of acid rain and contamination of lakes and rivers turned higher understood.

“Folks have been actually occupied with clear air and clear water, so I made a decision there would at all times be curiosity within the atmosphere,” Crawford says. She switched her main to civil and environmental engineering.

“You examine many areas in civil engineering, together with constructions, soils, transportation, and the atmosphere,” she says. After graduating in 1970, she stayed on on the college to earn a grasp’s diploma in civil engineering in 1973, specializing in environmental engineering.

She then pursued a Ph.D. in programs engineering at Ohio State College, in Columbus. Her analysis there centered on model-based system approaches and arithmetic.

When it got here time to discover a matter for her dissertation, she discovered that the U.S. Environmental Safety Company, in implementing the 1970 Clear Air Act, was struggling to ascertain baselines for air-quality ranges, she says.

“To make the most of these rules, you first should set up the place you presently are with air-quality ranges,” she says. Her dissertation centered on growing strategies to find out a baseline for concentrations of pollution within the ambiance primarily based on historic spatial-temporal measurements. She earned her Ph.D. in 1981.

She had deliberate to grow to be a marketing consultant for an environmentally associated group, however throughout her final 12 months at Ohio State a college member turned unwell, and the division requested her to show considered one of his courses.

“That’s how my profession took a flip towards academia,” she says.

Distant sensing applied sciences to sort out earth science issues

In 1980 Crawford joined the mechanical engineering division on the College of Texas at Austin, staying for 25 years. As a member of the commercial engineering and operations analysis group, she developed superior strategies for picture evaluation and purposes for mapping and monitoring land cowl utilizing satellite tv for pc imagery.

She additionally based an interdisciplinary analysis and purposes growth program in space-based and airborne distant sensing at UT. As a part of that effort, she put in and operated a receiving station to amass and analyze information from the U.S. Nationwide Oceanic and Atmospheric Administration’s satellites over prolonged areas of North America and the Gulf of Mexico.

Her group’s analysis program included initiatives in Australia and Africa. The group additionally developed new algorithms for evaluation of hyperspectral imagery, which offers detailed info throughout the electromagnetic spectrum to detect chemistry-based adjustments in vegetation.

Agriculture didn’t come again on her radar till 2006, when she joined the Purdue college. The college already had a 30-year historical past of collaboration between the universities of engineering and agriculture in utilizing distant sensing to deal with issues in agriculture resembling detection and mapping illness in crops. Researchers initially used aerial pictures, then satellite tv for pc photos. Via the college’s Laboratory for Purposes of Distant Sensing, the universities had developed worldwide collaborations in advancing evaluation of distant sensing information and growing open-source software program for purposes and schooling.

“Folks have been actually occupied with clear air and clear water, so I made a decision there would at all times be curiosity within the atmosphere.”

“After I instructed my household that Purdue had recruited me, my father requested whether or not the varsity understood that I didn’t know a lot about agriculture,” she says, laughing. “Purdue was occupied with my work in distant sensing and information analytics. These applied sciences present functionality to amass information ceaselessly over prolonged spatial areas—which is essential for agriculture.”

Her work is presently contributing to growing improved methods for purposes of vitamins and herbicides to crops. Via her contributions to plant breeding, she helps enhance the safety and resilience of meals manufacturing internationally.

Crawford not too long ago helped lead a undertaking funded by the U.S. Division of Vitality to develop unmanned aerial automobile platforms and algorithms to assist plant breeders in growing sorghum hybrids for biofuels—potential substitutes for corn-based ethanol.

Past academia, Crawford suggested NASA as a member of the Earth Science Advisory Committee and the advisory board for the NASA Socioeconomic Knowledge and Purposes Middle.

She was a Jefferson Science Fellow on the U.S. State Division, the place she centered on selling geospatial applied sciences in growing international locations.

In 2001 she realized her aim of engaged on a satellite tv for pc mission. She was a member of NASA’s Earth Observing–1 science validation group, which carried out the primary profitable U.S. civilian hyperspectral mission in area. Though it was designed for a lifetime of 18 months, the mission operated efficiently for 16 years. Her analysis centered on growing new strategies to research hyperspectral imagery to find out the response of vegetation to pure and man-made hazards.

The legacy of Mildred Dresselhaus

Crawford obtained the Dresselhaus Medal on 5 Might throughout the IEEE Imaginative and prescient, Innovation, and Challenges Summit and Honors Ceremony, held on the Hilton Atlanta.

Mildred Dresselhaus labored at MIT, which she joined in 1960 as a researcher in its Lincoln Laboratory Stable State Division, in Lexington, Mass. She turned a professor {of electrical} engineering in 1967 and joined the physics division in 1983.

In 2015 Dresselhaus turned the primary feminine recipient of the IEEE Medal of Honor. She died in 2017.

Crawford by no means met Dresselhaus, however she did obtain congratulatory messages from a number of individuals who knew her.

“Essentially the most wonderful factor to me has been the emails I obtained from so many individuals who knew her however didn’t know me,” Crawford says. “They have been former college students, colleagues, and buddies. They bolstered the notion that Dresselhaus was a very wonderful individual in addition to a trailblazer.”

One was an MIT electrical engineering scholar to whom she had given considered one of her previous spectrometers to start out his analysis. One other, who on the time was a junior college member on the College of North Carolina in Charlotte, recalled the considerate, essential enter and encouragement Dresselhaus supplied about her analysis throughout a go to to the college member’s lab.

“One among my colleagues at Purdue, who’s a well known researcher in nanotechnology, was emphatic in his appraisal,” she says. “He requested, ‘Do you understand she was the Queen of Carbon?’ It simply made me really feel so humble and appreciative.”

You may watch Crawford settle for her award on IEEE.television.

She was additionally an Innovators Showcase panelist throughout the summit.

Crawford stresses that her analysis is interdisciplinary: “My contribution is actually in growing algorithms to research information, however the goal is at all times to deal with an issue.

“To contribute to the answer, it’s essential to spend money on studying about the issue and to work collaboratively with others who’re specialists in that subject.

“Something that I’ve achieved throughout my profession is actually the results of a group. I accepted the award on behalf of all of us.”

IEEE: Staying linked to a neighborhood

Crawford joined IEEE when she started her tutorial profession and needed to publish her analysis. Greater than 50 of her papers are within the IEEE Xplore Digital Library.

“Publishing, for many individuals, is the entry into IEEE,” she says. “Then there may be development by way of understanding the significance of going to conferences and never solely listening to displays of analysis but in addition partaking with individuals. You begin taking note of what’s happening in an expert society, and also you begin volunteering. Then you might be a part of a neighborhood.”

Crawford served as 2013 president of the IEEE Geoscience and Distant Sensing Society and was an affiliate editor of the IEEE Transactions on Geoscience and Distant Sensing. She additionally has served on a number of of the society’s administrative committees. Her work was acknowledged with the GRSS 2020 Excellent Service Award and its 2021David Landgrebe Award.

Volunteering, she says, is “a two-way avenue since you contribute to the society however you additionally profit by way of your engagement with people and growing management expertise.”

Being concerned offers alternatives, she provides: “People who find themselves fairly achieved of their subject attend the conferences, and so they’re engaged with the society. You’d by no means, as a junior individual, sometimes have alternatives to fulfill these individuals.”
