Guiyang 3D land lifecycle management project recognized for innovation

The "3D Real-Scene-Based Land Lifecycle Management Demonstration Application" developed by the Guiyang bureau of natural resources and planning and the Guiyang Surveying and Mapping Institute has been selected as an exemplary innovative application in Guizhou's 3D real-scene technology initiatives.

Overview

The project utilizes the national pilot program for new foundational mapping in Guiyang. It integrates 3D visualization, spatial analysis, and entity information with natural resources and land management workflows. Incorporating 3D technology enables efficient land-use planning, covering all key stages from pre-approval to real estate registration. This system enhances approval precision and simplifies application processes for users.

Innovations

Building a geographic information digital foundation

The project combines oblique photography, LiDAR point clouds, digital elevation models (DEM), digital surface models (DSM), and orthophoto imagery. This data is merged with multi-temporal satellite images of Guiyang to create a comprehensive mapping infrastructure. Additionally, it links land management data, including planning, socio-economic statistics, real estate registration, and project approvals, forming an integrated 3D geographic information database.

Establishing 3D spatial data analysis models

The project uses 3D spatial-temporal data to enable advanced geospatial analysis, such as excavation-fill assessments, visibility analysis, solar exposure studies, height restrictions, and line-of-sight evaluations. It also provides real-time land-use data queries, supporting decisions on site selection, land acquisition, and urban planning.

Creating a model for land lifecycle management

The system visualizes natural resource maps, land-use planning, and architectural layouts using 3D real-scene technology. It also allows interactive compliance checks, conflict detection, statistical analysis, and spatial overlays, which support regulatory reviews, vacant land assessments, and illegal land-use detection. The system additionally integrates planning conditions and displays key metrics like building area, green space, and floor area ratio, forming a comprehensive land lifecycle management model.

Application benefits

Intelligent site selection with 3D technology

Real-scene 3D mapping enhances site selection by analyzing multi-temporal imagery and land-use compositions. Compliance analysis ensures that proposed sites do not encroach on protected zones or exceed urban development boundaries.

Smart planning approval

By integrating 3D planning models, users can visualize building placement and utilize real-time evaluation tools for factors like spacing, sunlight exposure, and skyline impact, streamlining the approval process.

Enhanced project management

Real-time 3D updates during construction allow stakeholders to assess project progress using point cloud data, oblique photography, and high-detail models. The system enables 360-degree visualization for compliance verification and regulatory oversight.

Advanced industry development

The project establishes a 3D spatial database supporting urban governance and resource management. Continuous integration of real-world data strengthens industry transformation, enabling precision management and digital innovation in natural resource oversight.
