Special Issue Information

Dear Colleagues,

In recent years, the integration of Artificial Intelligence (AI) with geospatial technologies has revolutionized the field of geodata science. In particular, the advent of Geospatial Artificial Intelligence (GeoAI) and Generative AI has significantly expanded the capabilities of traditional geospatial methods, allowing for unprecedented advancements in the mapping, extraction, generation, and analysis of spatial information. The integration of cutting-edge AI techniques with geospatial science has led to advancements across diverse disciplines and offered novel solutions to complex spatial challenges. GeoAI, with its specialized focus on geospatial data and analysis, harnesses the power of machine learning, deep learning, and other AI methodologies to tackle problems in geospatial domains. GeoAI methods have recently also encompassed Generative AI, which introduces a paradigm shift in spatial data generation, and has been used in geospatial tasks, such as in map labeling, image segmentation, the creation of synthetic spatial data, or AI-powered route optimization.

This Special Issue seeks to explore the transformative potential of AI in the realm of spatial data applications. It invites the submission of original research papers and review articles centered around the use of AI for mapping, extraction, generation, analysis, and communication of spatial data, which exemplify the novel methodologies, algorithms, and applications stemming from the integration of AI in processing and generation of spatial data. In addition to contributions that apply AI in geographic contexts, we encourage synergistic research that advances both the spatial sciences and AI research at large.

Topics of interest may include, but are not limited to:

  • Geospatial artificial intelligence (GeoAI);
  • Generative AI for geographic problems;
  • Foundation models in geographic context;
  • Spatial understanding, reasoning and literacy of large language models;
  • Big/crowdsourced data and AI;
  • AI assistants for mapping and cartography;
  • Multimodal AI systems for geospatial science;
  • AI and location intelligence;
  • AI-based spatial data analysis;
  • Machine learning and deep learning in GIS;
  • Conversional agents for spatial tasks;
  • Novel approaches for data storage and transfer (cloud-native, streaming, etc.);
  • Novel technologies in geocomputation and processing (serverless, edge AI, etc.);
  • Ethical, legal and privacy considerations of GeoAI.

In late 2023, the image-reading capability added to a Generative Pre-trained Transformer (GPT) framework provided the opportunity to potentially revolutionize the way we view and understand geographic maps, the core component of cartography, geography, and spatial data science. In this study, we explore reading and analyzing maps with the latest version of GPT-4-vision-preview (GPT-4V), to fully evaluate its advantages and disadvantages in comparison with human eye-based visual inspections. We found that GPT-4V is able to properly retrieve information from various types of maps in different scales and spatiotemporal resolutions. GPT-4V can also perform basic map analysis, such as identifying visual changes before and after a natural disaster. It has the potential to replace human efforts by examining batches of maps, accurately extracting information from maps, and linking observed patterns with its pre-trained large dataset. However, it is encumbered by limitations such as diminished accuracy in visual content extraction and a lack of validation. This paper sets an example of effectively using GPT-4V for map reading and analytical tasks, which is a promising application for large multimodal models, large language models, and artificial intelligence.

Rice yield is essential to global food security under increasingly frequent and severe climate change events. Spatial analysis of rice yields becomes more critical for regional action to ensure yields and reduce climate impacts. However, the understanding of the spatially varied geographical, climate, soil, and environmental factors of rice yields needs to be improved, leading to potentially biased local rice yield prediction and responses to climate change. This study develops a spatial machine learning-based approach that integrates machine learning and spatial stratified heterogeneity models to identify the determinants and spatial interactions of rice yields in the main rice-producing areas of China, the world’s largest rice-producing nation. A series of satellite remote sensing-derived variables are collected to characterize varied geographical, climate, soil, and environmental conditions and explain the spatial disparities of rice yields. The first step is to explore the spatial clustering patterns of the rice yield distributions using spatially global and local autocorrelation models. Next, a Geographically Optimal Zones-based Heterogeneity (GOZH) model, which integrates spatial stratified heterogeneity models and machine learning, is employed to explore the power of determinants (PD) of individual spatial variables in influencing the spatial disparities of rice yields. Third, geographically optimal zones are identified with the machine learning-derived optimal spatial overlay of multiple geographical variables. Finally, the overall PD of various variables affecting rice yield distributions is calculated using the multiple variables-determined geographically optimal zones and the GOZH model. The comparison between the developed spatial machine learning-based approach and previous related models demonstrates that the GOZH model is an effective and robust approach for identifying the spatial determinants and their spatial interactions with rice yields. The identified spatial determinants and their interactions are essential for enhancing regional agricultural management practices and optimizing resource allocation within diverse main rice-producing regions. The comprehensive understanding of the spatial determinants and heterogeneity of rice yields of this study has a broad impact on agricultural strategies and food security. Full article

The generation and prediction of daily human mobility patterns have raised significant interest in many scientific disciplines. Using various data sources, previous studies have examined several deep learning frameworks, such as the RNN and GAN, to synthesize human movements. Transformer models have been used frequently for image analysis and language processing, while the applications of these models on human mobility are limited. In this study, we construct a transformer model, including a self-attention-based embedding component and a Generative Pre-trained Transformer component, to learn daily movements. The embedding component takes regional attributes as input and learns regional relationships to output vector representations for locations, enabling the second component to generate different mobility patterns for various scenarios. The proposed model shows satisfactory performance for generating and predicting human mobilities, superior to a Long Short-Term Memory model in terms of several aggregated statistics and sequential characteristics. Further examination indicates that the proposed model learned the spatial structure and the temporal relationship of human mobility, which generally agrees with our empirical analysis. This observation suggests that the transformer framework can be a promising model for learning and understanding human movements. Full article

Estimating disaster relief supplies is crucial for governments coordinating and executing disaster relief operations. Rapid and accurate estimation of disaster relief supplies can assist the government to optimize the allocation of resources and better organize relief efforts. Traditional approaches for estimating disaster supplies are based on census data and regional risk assessments. However, these methods are often static and lack timely updates, which can result in significant disparities between the availability and demand of relief supplies. Social media, network maps, and other sources of big data contain a large amount of real-time disaster-related information that can promptly reflect the occurrence of a disaster and the relief requirements of the affected residents in a given region. Based on this information, this study presents a model to estimate the demand for disaster relief supplies using social media data. This study employs a deep learning approach to extract real-time disaster information from social media big data and integrates it with a spatial information diffusion model to estimate the population in need of relief in the affected regions. Additionally, this study estimates the demand for emergency materials based on the population in need of relief. These findings indicate that social media data can capture information on the demand for relief materials in disaster-affected regions. Moreover, integrating social media big data with traditional static data can effectively improve the accuracy and timeliness of estimating the demand for disaster relief supplies. Full article
