The Urban Space Information Platform: Opportunities and Challenges

Urban construction and development rely on the efficient use of geospatial information. The urban spatial information platform (USIP) serves as a centralized hub for managing and applying multisource urban data. However, the increasing volume and complexity of urban data pose significant challenges in management and processing. This article systematically reviews the theory and technology of USIP, analyzing its current status and future directions. We explore the diversity of data sources in urban scenarios and their characteristics. For data management, we review organization and storage technologies, and for data processing, we analyze architectures and mainstream methods. Furthermore, several practical applications of USIP and its impact on urban development are discussed. This study examines USIP’s advancements from a full-chain perspective, encompassing data acquisition, technological implementation, and key applications, offering valuable insights for future research and practice.
