3D GIS Platform Requirements
1. Overall Requirements
1.1. Layout: 3D map in the center; function menu bar at the top, multiple resource list panels on the left, multiple detail views of current events on the right, and multiple overall feature visualization icons at the bottom. Each chart window can be closed or expanded to full screen.
1.2. B/S architecture preferred
1.3. Mobile operation support
1.4. System startup interface: The system operates in camera mode, gradually advancing toward the target location. The system supports planning mode and live-view mode.
1.5. Surface building display
1.6. Underground structure display
1.7. Indoor structure display
2. Modeling Requirements
2.1. 3D modeling: Import 3D models to build a 3D campus, including buildings, floors, zones, shelves, and other information.
2.2. Rapid modeling: Quickly create product models through photography, and quickly build models using 3D scanners.
2.3. Common products are placed in the toolbar and can be dragged to hotspots or adjusted afterward to build scenes, such as shelves, goods, AGV carts, positioning base stations, cameras, fans, lighting, temperature/humidity sensors, etc.
2.4. Support and integration of multiple modeling methods: Based on existing planning drawings, remote sensing imagery, and related attribute data, combined with on-site surveys, use software for mass generation and 3DMAX for individual modeling. Combine current status with planning to quickly and realistically reproduce the urban 3D scene.
2.5. AR image enhancement and fusion modeling
2.6. Reasonable classification of facilities:
3. Operation Requirements
3.1. User permissions and login management: The permission matrix can be imported/exported via Excel spreadsheets.
3.2. Base map loading: WMS services such as Baidu, Amap, Tianditu, etc., with switchable display.
3.3. Flight display: Pre-design routes and set relevant parameters (including viewing angle, field of view, view distance, flight altitude, speed, etc.). During flight, the observer's line of sight follows the pre-designed route, and various parameters can be changed in real time during the flight.
3.4. Roaming display: Use designated keys to move forward/backward along any route and in any direction, with real-time adjustment of viewing angle, field of view, view distance, flight angle, and altitude.
3.5. Annotation requirements
3.6. Save viewpoint, jump to viewpoint
Save the current viewpoint; enter latitude/longitude to jump to a specified location.
3.7. AR live-view distortion correction and overlay
3.8. Scene zoom in/out, pan, and rotation can be operated in real time using tools or by setting parameters.
3.9. Graphic output: Real-time rendered scenes can be directly saved as bitmaps (size range can be set via parameters).
Animation output: The entire path flight process can be recorded as an animation for playback outside the 3DGS platform.
3.10. Hide/load models
3D models can be dynamically loaded or hidden (for demonstration purposes, all models are magnified several hundred times); drawing functions on the map apply to all models, and models within the range are automatically highlighted and displayed; clicking a model centers it automatically and prompts whether to jump to the BIM model (or other vector formats) for display (the BIM model is also based on WebGL).
