Algorithm for Identifying Micro-Update Potential in Urban Corner Spatial Environment Design by Integrating Multi-Source Data Jing Zhang1* 1 College of Arts, Shandong Jianzhu University, Jinan, Shandong, China * Corresponding author: Jing Zhang. Email: outlook_8A9201AAC2554F63@outlook.com Journal of Digital Frontier 2026, Vol. 1, No. 1, pp. 106-143 DOI: 10.67541/jdf2605 Received: 31 May 2026; Revised: 17 July 2026; Accepted: 29 July 2026; Published: 21 August 2026 Abstract <p>Aiming at the problems of multi source data heterogeneity, insufficient environmental representation, and insufficient spatial correlation description in the potential recognition of urban corner space micro-renewal, a potential recognition method based on multi source data and spatial relationship enhancement learning is proposed. By integrating remote sensing images, street view images, POI data, road network data, building form data, land use data, and population activity data, multi scale environmental features are constructed, and a cross modal attention mechanism and a multi relation graph attention network are introduced to realize heterogeneous feature interaction and neighborhood spatial dependence modeling. On 1,216 urban corner space samples, the accuracy, F1 score, ROC AUC, and PR AUC of the proposed model reach 0.887, 0.881, 0.946 and 0.921 respectively, which is 3.3 percentage points higher than that of the standard GAT. Ablation, cross region migration, and perturbation experiments further verify the effectiveness, generalization ability and robustness of the model. This study can provide data-driven technical support for automatic screening of urban corner space, prioritization of micro-update and fine governance.</p> Keywords Urban corner space Multi-source data fusion Cross-modal attention Graph attention network Micro update potential identification References Chen, L., Cheng, Y., Zhou, Z., &amp; Wen, Y.
