This invention relates to a method for 3D digital display of urban assets, based on an eight-part model and ten-level spatial geographic boundaries, to present and express different categories of urban assets in three dimensions. The eight-part model includes hierarchical, categorical, segmented, block-based, building-based, layered, household-based, and zone-based classifications. The ten-level spatial geographic boundaries include city-level, district-level, street-level,
community-level, grid-level, building-level, floor-level, room-level, block-level, and element-level classifications. This invention can dynamically express spatiotemporal two-dimensional and three-dimensional data from multiple sources and with different structures, loading content of interest into a 3D scene according to
user needs, thereby reducing unnecessary memory usage in the
system and enhancing user experience. It also solves problems such as high latency and slow loading speed in
network data services, achieving the technical effects of small
memory footprint, fast loading speed, comprehensive data types, excellent presentation effects, realistic digital expression, and easy updates.
