Special Issue Information

Dear Colleagues,

Spatial analysis and modeling (SAM) serves as a powerful tool for understanding the complexity of geospatial phenomena. With the availability of high-resolution geospatial data and the increasing complexities of geospatial analytics approaches, the resolution of geospatial problems using these data and approaches poses significant computational challenges.

The past decades have witnessed advances in both computing and modeling performance by advanced computational approaches. These advanced computational approaches comprise machine learning algorithms (e.g., artificial neural networks, random forests, evolutionary algorithms, and swarm intelligence) and cyberinfrastructure (e.g., high-performance computing, cloud computing, and web technologies). With their powerful and intellectual abilities, advanced computational approaches for SAM have gained increasing attention from researchers interested in the study of spatially explicit phenomena.

This Special Issue originates from the AAG Annual Meeting session of “Symposium on Frontiers in CyberGIS and Geospatial Data Science: Advances in Computational Approaches for Spatial Analysis and Modeling”, held in Denver, CO, USA, on April 6–10, 2020. This session aims to gather researchers sharing their experiences of advanced computational approaches to the SAM community. While papers in this section are invited to this Special Issue, other original works aligned with this topic are highly welcomed.

Relevant topics include, but not limited to:

  • Applications of artificial intelligence techniques
  • Applications of cyberinfrastructure
  • Geovisualization and geovisual analytics
  • Innovative algorithms for spatial analysis and modeling
  • Address challenges in big geospatial data
  • New approaches or improvement of existing computational approaches

Geographically weighted regression (GWR) introduces the distance weighted kernel function to examine the non-stationarity of geographical phenomena and improve the performance of global regression. However, GWR calibration becomes critical when using a serial computing mode to process large volumes of data. To address this problem, an improved approach based on the compute unified device architecture (CUDA) parallel architecture fast-parallel-GWR (FPGWR) is proposed in this paper to efficiently handle the computational demands of performing GWR over millions of data points. FPGWR is capable of decomposing the serial process into parallel atomic modules and optimizing the memory usage. To verify the computing capability of FPGWR, we designed simulation datasets and performed corresponding testing experiments. We also compared the performance of FPGWR and other GWR software packages using open datasets. The results show that the runtime of FPGWR is negatively correlated with the CUDA core number, and the calculation efficiency of FPGWR achieves a rate of thousands or even tens of thousands times faster than the traditional GWR algorithms. FPGWR provides an effective tool for exploring spatial heterogeneity for large-scale geographic data (geodata). Full article

Unstructured geo-text annotations volunteered by users of web map services enrich the basic geographic data. However, irrelevant geo-texts can be added to the web map, and these geo-texts reduce utility to users. Therefore, this study proposes a method to detect uncorrelated geo-text annotations based on Voronoi k-order neighborhood partition and auto-correlation statistical models. On the basis of the geo-text classification and semantic vector transformation, a quantitative description method for spatial autocorrelation was established by the Voronoi weighting method of inverse vicinity distance. The Voronoi k-order neighborhood self-growth strategy was used to detect the minimum convergence neighborhood for spatial autocorrelation. The Pearson method was used to calculate the correlation degree of the geo-text in the convergence region and then deduce the type of geo-text to be filtered. Experimental results showed that for given geo-text types in the study region, the proposed method effectively calculated the correlation between new geo-texts and the convergence region, providing an effective suggestion for preventing uncorrelated geo-text from uploading to the web map environment.
