The market is projected to reach USD 845.7 billion in value by 2029 at a CAGR of 16.9%, so it’s clearly rapidly expanding.
Yet, the concept of ‘geospatial data science’ is still somewhat… nebulous for most people. And if you wish to effectively apply geospatial data science solutions within your organization, you first need to have a clear understanding of everything that entails.
This is precisely why we wrote this guide. By reading it, you will learn everything you could wish to know about geospatial data science – from the foundational concepts to the methods and techniques that are applied to the practical uses. So, let’s get started.
What Is Geospatial Data Science?
Geospatial data science, sometimes referred to as spatial data science or geospatial analytics, is a multidisciplinary field that deals with the study of data with a geographic component. Geospatial data science is all about the art and science of collecting, analyzing, and interpreting data related to location and geography.
It’s the marriage of geographic information systems (GIS), data analysis, visualization, and machine learning techniques. Its ultimate purpose is to extract valuable insights from large volumes of geospatial data.
Key Concepts in Geospatial Data Science
To grasp the essence of geospatial data science, it’s essential to understand its key concepts:
- Spatial Data: This refers to data that has a geographical component, such as coordinates, addresses, or polygons representing areas.
- GIS: Geographic Information Systems are the software and tools used to capture, store, manipulate, analyze, and visualize spatial data.
- Geospatial Data: Spatial data with added attribute and temporal information.
- Geospatial Analysis: The process of examining, modeling, and interpreting patterns and relationships in spatial data, often with the use of AI and ML tools.
- Data Visualization: Presenting geospatial data in a visual format, often through maps, charts, or 3D models.
Note: To clear up a common misunderstanding, Geographical Information Systems and geospatial data science are not the same concept. While they are closely related, GIS is but a part of geospatial data science. In the simplest of terms, GIS deals with the question of where something is happening, while geospatial data science integrates that information, builds on it, and tries to answer how and why.
Explaining Geospatial Data Analysis
Analyzing geospatial data is a multifaceted process. Our Guide to Geospatial Data Analysis will provide you with a more in-depth look into the essential methods and techniques used in this field. From spatial statistics to machine learning, you’ll discover the tools that empower data scientists in their geospatial endeavors. Here, we will provide a short overview.
What Is Geospatial Data?
We mentioned that geospatial data is spatial data with added attribute and temporal information. Attribute information is any information that describes the non-spatial characteristics of a location and adds context but is not purely limited to its geographical description.
So, spatial data about a city would be information that is represented through rasters and vectors – like the specific location, exact boundaries, its network of roads, building placement, etc. Attribute information could be economic or demographic data, weather information, etc. – whatever information is necessary for in-depth geospatial analysis.
Temporal data adds the temporal dimension to spatial and attribute data. So, how things have changed over time. This is a key component of geospatial analysis because it helps find patterns that can uncover future trends. Thus, geospatial analysis rests on the incorporation and interpretation of spatial, attribute, and temporal information.
Methods and Techniques in Geospatial Data Analysis
In geospatial data analysis, there are several methods and techniques that are used in combination to uncover deeper insights from geospatial data:
- Spatial Statistics: These statistical methods are specifically designed to analyze spatial data. They include spatial autocorrelation, spatial interpolation, and point pattern analysis.
- Remote Sensing: This involves collecting satellite imagery, aerial images, or drones to monitor changes in the Earth’s surface, such as deforestation or land use changes.
- Machine Learning: Machine learning algorithms are utilized to analyze large volumes of spatial data in combination with attribute and temporal information and look for patterns and trends.
It is important to note that machine learning is a key facet of geospatial data analysis. Even if all the other elements were combined, geospatial data analysis would not exist without the help of AI and ML solutions.
The Importance of Geospatial Predictive Analysis
Geospatial predictive analysis is a subset of geospatial data analysis and is one of the cornerstones of geospatial data science. By leveraging historical data, real-time spatial data, and cutting-edge algorithms, it allows us to anticipate future trends and make informed decisions.
Geospatial predictive analysis is typically done in four steps:
- Data Acquisition – gathering the geospatial data relevant to a project;
- Data Cleaning and Curation – processing the data to ensure that it is accurate, relevant, and consistent;
- Data Annotation – labeling and annotating the data so that it can be used as training data for geospatial machine learning algorithms;
- Data Analysis – utilizing ML models to analyze the collected, processed, and annotated data to predict future trends and events.
The Power of Predictive Analysis in Geospatial Data Science
Machine learning algorithms can relatively quickly analyze large datasets of geographic information to identify patterns and make predictions. Whether it’s predicting disease outbreaks, traffic congestion, or crop yields, the applications of predictive analysis in spatial data science are vast.
Geospatial predictive analysis aids in disaster management by forecasting the path of hurricanes or floods, allowing authorities to take preemptive measures. It can predict where the next wildfire is likely to occur based on historical fire data and weather conditions.
Predictive analysis also plays a crucial role in urban planning, helping city officials anticipate population growth and plan infrastructure development accordingly. And, again, all of this is done through the power of machine learning. Which is a good segway into the next topic.
Geospatial AI Solutions
Geospatial data science and artificial intelligence (AI) are a potent combination and not just for predictive analysis. There are many real-world applications of AI in solving complex geographic challenges.
Every industry benefits from geospatial insights differently. Here, we will explore the impact of geospatial data science in various sectors, showcasing how it revolutionizes decision-making and planning.
In agriculture, spatial data science aids in precision farming. Farmers use GPS and remote sensing data to monitor crop health, optimize irrigation, and reduce waste. By precisely targeting resources, they can increase yields and sustainability.
Self-driving cars run on AI and remote sensing. AI models are trained to continuously detect and process spatial information, which allows them to inform the path of the vehicles. This is one of the more popular uses for geoAI in recent years.
In healthcare, geospatial data science can improve disease tracking and resource allocation. By analyzing the geographic spread of diseases, health officials can respond more effectively to outbreaks and allocate medical resources where they are needed most.
Urban planners rely on geospatial data to design efficient transportation networks, allocate resources, and enhance the quality of life for city dwellers. Traffic analysis, land-use planning, and disaster preparedness are just a few areas where spatial data science plays a vital role.
Environmental scientists use geospatial data to monitor changes in ecosystems, track deforestation, and analyze climate patterns. This data helps in understanding and mitigating the impacts of climate change.
Best Practices in Geospatial Data Science
Success in geospatial data science relies on more than just tools and data. There are best practices that data scientists apply in their day-to-day work in order to see geospatial projects to successful completion. And it all starts with:
- Data Quality: Data needs to be accurate and up-to-date. Poor data quality can lead to erroneous conclusions. As data scientists like to say, ‘rubbish in, rubbish out’, i.e., no AI and ML model can perform its function if the data it uses is bad.
- Ethical and Legal Considerations: Privacy, ethical, and legal concerns always exist when dealing with location data, especially in sensitive areas. Every geospatial project needs to adhere to strict ethical and legal requirements.
- Interdisciplinary Collaboration: Geospatial data science often requires collaboration between domain experts and data scientists to ensure meaningful insights.
Tools and Technologies in Geospatial Data Science
We said that geospatial data science relies on more than just tools, but tools and technologies are still invaluable to geospatial data scientists. Here is a short overview of some of the most popular software, libraries, and resources that streamline the work.
- GIS Software: Geographic Information Systems software like ArcGIS, QGIS, and MapInfo provide a foundation for spatial data analysis and visualization.
- Programming Languages: Python, R, and Julia are popular languages for geospatial data analysis, with libraries like GeoPandas and Shapely.
- Remote Sensing Tools: Software for processing and analyzing remote sensing data from satellites and drones, including ENVI and Erdas Imagine.
Emerging Trends in Geospatial Data Science
Spatial data science is a relatively new field. As such, it is quickly evolving. Two of the more interesting emerging trends are the Internet of Things (IoT) integration and 3D mapping and augmented reality (AR).
The Internet of Things refers to the network of interconnected physical devices, objects, or “things” that can communicate and exchange data with each other over the internet. These devices, equipped with sensors, software, and connectivity, enable them to collect, transmit, and receive information, often without direct human intervention.
The proliferation of IoT is transforming how we interact with the digital and physical worlds, facilitating automation, remote monitoring, and real-time insights and is generating massive amounts of geospatial data. Integrating IoT sensor data with geospatial analytics is leading to more comprehensive insights.
3D modeling and AR are enhancing how we visualize data They enable users to overlay geospatial information onto the real world, providing immersive experiences and precise location-based insights.
In 3D, terrain modeling and building visualization aid urban planning and environmental assessments. AR applications, like geospatial navigation, allow users to access real-time data, such as street names and business information when exploring unfamiliar locations.
Together, 3D and AR technologies empower geospatial data scientists to create interactive, context-aware environments, improving decision-making, urban design, and fieldwork efficiency. And this technology can still be considered in its infancy.
