Please note this is a comparison between Version 2 by Abigail Zou and Version 1 by Chaowei Yang.

The world evolves continuously across space and time. Massive volumes of data are generated through sensing, simulation, remote observation, and human activities, capturing dynamic processes in environmental, social, economic, and engineered systems. Critical insights are embedded within these large-scale spatiotemporal datasets. Spatiotemporal Data Science provides a conceptual and methodological framework for analyzing such data by integrating spatiotemporal thinking, computational infrastructure, artificial intelligence, and domain knowledge. The field advances methods for data acquisition, harmonization, modeling, visualization, and decision support, enabling applications in natural disaster response, public health, climate adaptation, infrastructure resilience, and geopolitical analysis. By leveraging emerging technologies—including generative Artificial Intelligence (AI), large-scale cloud platforms, Graphics Processing Unit (GPU) acceleration, and digital twin systems—Spatiotemporal Data Science enables scalable, interoperable, and solution-oriented research and innovation. It represents a critical frontier for scientific discovery, engineering advancement, technological innovation, education, and societal benefit. Spatiotemporal Data Science is a transdisciplinary field that studies and models dynamic phenomena across space and time by integrating spatial theory, temporal reasoning, artificial intelligence, and scalable computational infrastructure. It enables the development of adaptive, predictive, and increasingly autonomous systems for understanding and managing complex real-world processes.

Scientific and engineering inquiry has traditionally followed an iterative cycle: observation of phenomena, formulation of hypotheses, data collection, experimentation, validation, and refinement of theory. While this cycle remains foundational, the digital transformation of science has profoundly reshaped how data are collected, stored, analyzed, and interpreted [1].
Since the invention of the computer in the mid-20th century, scientific data have shifted from analog formats to digital representations. Advances in sensing technologies, including satellite remote sensing, in situ sensor networks, mobile devices, Global Position System (GPS) technologies, and Internet-connected IoT devices, have enabled unprecedented volumes of data generation at high spatial and temporal resolutions [2]. These developments underpin transformative visions such as Digital Earth by Al Gore [3], the 4th paradigm data-intensive science initiated by Jim Gray [4], digital twins [5], autonomous systems [6], and large-scale simulation-based scientific discovery [7].
Recent digital transformations have enabled the collection of data at unprecedented spatial and temporal resolutions, thereby enabling scientific and engineering inquiries to be addressed in a spatiotemporal context. The intellectual roots of spatiotemporal thinking trace back to early human activities—estimating distances for hunting, tracking seasonal cycles for agriculture, and organizing movement across landscapes [8]. Formal academic foundations emerged through spatiotemporal statistical analyses [9], the first law of geography [10], time geography [11], environmental modeling [12], regional and geospatial science [13], spatial statistics [14[14][15],15], temporal Geographic Information System (GIS) [16], and computing simulation for scientific discovery [17].
Petabyte-level datasets are now common across disciplines, and extracting actionable information requires new methodological frameworks and computing infrastructure [18]. Recent global challenges—including COVID-19 [19], flooding [20], wildfires [21], air pollution [22], supply chain instability [23], and geopolitical conflict [24]—underscore the urgent need for self-adjusting systems capable of perceiving, modeling, and responding to dynamic phenomena as they unfold. These challenges require more than traditional spatial or temporal analysis. They demand integrated spatiotemporal intelligence architectures that combine large-scale data processing, predictive modeling, uncertainty quantification, and real-time decision support. Building upon early foundations in spatial big data science [25[25][26],26], this entry conceptualizes Spatiotemporal Data Science at the convergence of (e.g., [27]):
  • Domain sciences, which provide a mechanistic understanding of environmental, climatic, public health, engineering, economic, and social systems [28];
  • Data science and artificial intelligence, including statistical inference, spatial analytics, machine learning, and deep learning [29], enable pattern discovery, predictive reasoning, and model generalization [25];
  • Advanced computational infrastructure, such as cloud-native architectures, GPU acceleration, Field-Programmable Gate Array (FPGA) systems, and edge computing platforms, supporting scalable, real-time intelligence [30];
  • Human spatiotemporal cognition [31], which informs how individuals perceive movement, constraints, risk, and temporal evolution across personal, logistical, and societal systems [11] for analyzing and modeling movements [32];
  • Education and workforce development, which cultivate spatiotemporal reasoning skills and prepare practitioners to design, interpret, and govern intelligent, data-driven systems [33], and use spatiotemporal analytics to evaluate education and pedagogy [34].
Through this convergence, Spatiotemporal Data Science moves beyond static spatial analysis [35] toward an adaptive intelligence paradigm that integrates data-driven learning, physics-based reasoning, and scalable computational infrastructure. This shift enables continuous model updating, cross-domain integration, and increasingly autonomous decision-making in complex, nonstationary systems. The field extends beyond analytical methods to include infrastructure design, interdisciplinary integration, knowledge translation, and operational deployment—transforming descriptive mapping into predictive, feedback-driven modeling of evolving systems. It establishes the foundation for adaptive digital ecosystems that synchronize data, models, and physical environments. Spatiotemporal Data Science transforms static geospatial analysis into adaptive intelligence systems that continuously learn from, predict, and interact with dynamic real-world processes.
