The EO Hub section of our site is dedicated to highlighting the key trends and use cases within the EO and geospatial sector. But, what if we looked beyond industry and shifted our focus to science? What are researchers coming together to investigate? What areas of interest are being funded, researched, and published across the world?
To find out we analyzed 6000 research articles published on the Springer Nature website from January 2023 to June 2024—revealing some intriguing insights.
We used Springer’s API and targeted keywords like “geospatial” and “remote sensing“. By doing so, we discovered key research topics, current trends, and themes, and took note of the countries with the most published articles on specific topics.
So, what topics are researchers looking at? That’s where keywords come in.
Reviewing Research: Why are Keyword Trends So Telling?
Keywords are an excellent marker to describe trends in research areas. They tell us a lot about how the field is developing, inform business decisions, and detect changes in research priorities.
Our review aimed to find the most popular keywords and technologies featured in research paper titles and abstracts. We then visualized the locations of these papers per country on a world map.
At the forefront of this is Springer Nature, one of the leading international scientific publishers. Springer publishes over 200 articles each month focused on remote sensing and geospatial. From satellite imagery techniques to GIS applications and advanced data analysis methods, Springer is a useful resource for researchers, industry professionals, and curious minds alike.

-
“Landslide”, “Erosion, “Soil”, Displacement”, “Movement”
Scientists frequently use keywords like “landslide”, “erosion”, “soil”, “displacement”, and “movement” to study the dynamics of the Earth’s surface and the factors contributing to land instability. These terms are essential for understanding natural hazards, soil degradation, and ground displacement, and critical for risk assessment or disaster management. 328 of the articles mentioned the keyword “landslide”, 361 talked about “erosion”, 1051 included the word “soil”, 63 used “displacement”, and 154 discussed “movement”. In total – almost 2000 mentions!
-
“Model” and “Modeling”
In the context of geospatial and remote sensing research, the keywords “model” and “modeling” are often used to describe the process of creating simulations and predictive tools that analyze spatial data and environmental changes. These terms are crucial for developing and testing hypotheses, and forecasting future conditions. An impressive number of 2931 mentions were detected in our research.
Top Keyword Phrases:
Now that we’ve taken a look at the single keywords currently trending, we wanted to cross-check this with keyword phrases that are shaping the research landscape. While individual keywords offer valuable insights into research trends, examining keyword phrases provides a more nuanced understanding of the current research landscape.
Our review points towards several dominant themes:
-
“Land Cover” and “Land Use”
The phrases “Land cover” and “Land use” appear as primary focus areas, underscoring the role of EO in mapping the Earth’s surface. Many articles address the topic of land use and land cover classification using EO, which supports development and enhances the accuracy of following GIS analyses. As many as 1925 articles contained these keyphrases.
-
“Remote Sensing”
We found that “Remote sensing” remains a cornerstone phrase, reflecting the continuous evolution of sensor technologies. These advancements enable more accurate and detailed data collection, revolutionizing our ability to monitor and analyze Earth’s systems. If we look at the occurrence of this phrase over the years, there has been over a fivefold increase in frequency of use between 2006 and 2023. “Remote sensing” keyphrase occurred 1203 contained in revised articles.
