A new study published in Geomatics shows that China is by far doing the most research on remote sensing, and U.S. remote sensing research has dropped. Phys.org describes remote sensing as follows:
‘Remote sensing—the science of gathering information from a
distance using technologies like laser scanning, imagery, and hyperspectral
imagery from the ground, the air, and even space—underpins critical
applications from autonomous vehicles to climate monitoring and national
security.”
NASA’s definition of remote
sensing is more concise:
“Remote sensing is the acquiring of information from a
distance.”
The exponential growth of
remote sensing research in China has been attributed to several factors.
“Laefer and co-author Jingru Hua—at the time a master's
student in the NYU Center for Data Science—attribute this surge to decreased
equipment costs, greater global participation, digital-only publishing, and
most significantly, the adoption of artificial intelligence techniques like
machine learning and deep learning.”
Another key factor is funding
from China's National Natural Science Foundation, which funds 53% of papers
from 2021-2023, while the U.S. only funds about 5% of those. U.S. funding
entities for remote sensing research are basically the National Science
Foundation and NASA. NASA funding for such research has dropped considerably in
recent years. NASA has no direct funding for geomatics (the science of
gathering and analyzing geographic data) or geodesy (the science of measuring
Earth's shape and positions on it).
China also now accounts for
the majority of remote sensing patents.
“Early decades focused heavily on satellite imagery, but
recent years show explosive growth in artificial intelligence techniques, with
terms like "deep learning" and "machine learning" now
dominating publication titles. The number of papers mentioning these techniques
has grown exponentially, reaching over 80,000 publications by 2023.”
“The findings have implications for technological
competitiveness. Remote sensing capabilities underpin emerging technologies
including augmented reality, autonomous navigation, and digital twins, all
important areas for economic and commercial applications.”
Although in this case,
China’s increased focus on remote sensing research has been going on for a
while, more recent trends include less focus on research in the U.S.,
especially with the new Trump administration, which has significantly cut
scientific research funding from universities and the government. Basically,
that means that China is catching up in R&D competition. I believe we need
to retain our edge by investing more, not less, in research.
The paper’s abstract and some
figures from the paper are given below. One notes that more papers are
mentioning machine learning and deep learning in regard to remote sensing.
Thus, AI/machine learning is becoming a feature of some remote sensing
algorithms. The last two figures show China’s recent dominance in the number of
patents filed.
