Web GIS & Drone Photogrammetry Bring Benefits to Smart City Management

Digital transformation is becoming a standard rather than an exception by now. Smart City management is now required more and more multi-dimension data fusion, data analytics and data mining. Especially required to leverage location-based analytics to connect people with information and technology, and help them improve their quality of life and make better choices.

Hightopo visualization solution integrated with related GIS (Geographic Information System) technology to drive further development, brings all aspects together and enables the consistent use of digital models and data to open numerous new opportunities, offer new service and efficient operation benefit the smart city ecosystem. Empowering businesses to gain a competitive advantage with location intelligence.

Smart City Lightweight 3D Modeling

• Drone Photography Modeling

Oblique aerial photograph is taken with the axis of the camera held at an angle between the horizontal plane of the ground and the vertical plane perpendicular to the ground. It’s a GIS technology that has developed rapidly in recent years. The aircraft or drone is equipped with multiple sensors to capture the ground objects from the front, back, left, right, and vertical five directions to quickly and efficiently obtain data information that truly reflects the ground conditions. Through a series of professional processing operations such as correction, adjustment, and multi-view image matching, to create a 3D model.

• BIM

BIM (Building Information Modeling) is the holistic process of creating and managing information for a built asset. However, since BIM file contains massive data and it’s usually too heavy on the web, Hightopo offers a BIM convert solution that allows users to select part of data so that the model will be lightweight and have smooth operation efficiency.

• Manual Modeling

It must be clarified that since models are the mapping and restoration of the real world, it depends on various data sources, including point cloud data, tilt photography, satellite images, panoramic images, aerial video, etc. However, these real data are more or less problematic, so a secondary design is needed to achieve accurate geographic location, matching regional style, and smooth operation efficiency.

For those buildings that required a high level of detail, manual modelling comes in handy. Designers will utilize CAD, aerial photography, satellite images, on-site images, etc as references to model the building or the inside equipment/devices. Then input to HT, to achieve an interactive Web 3D scene, which can be zoomed, translated, and rotated. Each device in the scene can respond to interactive events.

Weather Simulation

HT powerful graphic rendering engine enables dynamic weather simulation on the web. By integrating with the weather system, the interactive scene will simulate different weather scenarios. Also display the temperature, air quality, and related information.

3D Walk-through & Fly-through

HT integrated GIS and remains the walk-through and fly-through functionality, allows users to patrol and roam the area from a first-person perspective according to a pre-set route.

Industrial Park Management

Hightopo offers a one-stop comprehensive visualization solution from industrial park construction, underground pipeline management, attracting investment to traffic management. Empower operators and managers to track each phase and be prepared for what is next.

•Underground Pipeline Construction

In terms of land use planning, they are distinguished by different colour blocks. Through analysis of land use distribution, land use requirements, functional positioning, etc., to reasonably determine the development intensity, land use scale and control requirements of the plots.

The underground pipeline system not only solves the problem of urban traffic congestion but also greatly facilitates the maintenance and overhaul of municipal facilities such as water, electricity, gas, heat, and communications. Hightopo uses lightweight modelling technology to simulate the underground pipelines, and utilize 3D visualization, it greatly improves the quality of the operation and maintenance service of the integrated pipeline gallery, and accelerates the construction of a 3D green pipe gallery with intelligent control and intelligent operation and maintenance.

•Investment Attraction

Investment attraction is an important work after the completion of the smart park. The investment in the park is mainly about the leasing and rent of the buildings in the park; the placement of advertising spaces in the park; the distribution and usage of park parking lots and the distribution of POI (Point of Interest) data of the park service facilities, etc. The overall investment promotion situation is fully presented, attracting more enterprises to enter the park. Smart investment in the park allows the industrial park operators and managers to save a lot of time and labour costs, and improve the efficiency of investment.

•Traffic Management & Video Fusion in 3D Environment

The visualization of traffic supervision creates a “Skynet” in the park through a series of connections and integrations of traffic monitory and supervision system, which allows a comprehensive control and management of current traffic.

Video Fusion or virtual and real fusion technology is one of the key links in video enhancement of 3D geographical scenes. The video images are accurately fused and displayed in the real and precise geographic coordinates of the space corresponding to the 3D model. This fusion will not cause dislocation due to interaction such as dragging and rotating the 3D model.

HIghtopo video fusion technology uses WebGL technology and uses GPU high-performance computing capabilities to process video images in real-time. Image processing does not occupy CPU resources, to make sure of a smooth loading.

Building Management

Hightopo offers an enhanced solution to traditional BA building management need. The system connects to and synchronizes with building devices through IoT technologies, facilitating an integrated operating system for device maintenance, lighting, ventilation, security, fire control, and elevator, all presented with 3d visualization to maximize efficiency.

•Elevator System

The sci-fi wireframe style design enables an intuitive visual of elevators real-time operation status. The data source from the elevators system will trigger the animation and display key data on side pannels.

•Lighting System

Integrate the lighting system inside and outside the building, use the HT Smart City visualization platform to centrally monitor the lighting equipment in the building, adjust the lighting effect mode at different times, analyze the environmental illuminance and lighting energy consumption through the data trend graph. The running status of lighting detection is updated in real-time so that managers can deal with lighting system problems in time, problems can be discovered and dealt with in a timely manner, and improving the management efficiency and service level of the building.

•Fire System

The fire equipment location is indicated with the red light point in the scene. The operation and monitoring status of each fire equipment; the number of smoke and electrical fires; the number of fire alarms; the real-time update dynamics of the firewater pressure, and the abnormal situation all can be checked and displayed on the data panel.

When a disaster occurs, the visualization system can quickly know where the problem is, so that firefighters can execute the corresponding plan, complete the planning of the optimal escape route, call the alarm system and broadcast to remind the people in the building to escape from danger, and ensure the safety of lives and properties inside the building.

•AC & Ventilation System

Visualize and monitor the environment status such as outdoor PM value, temperature and humidity, wind speed, and indoor real-time temperature, humidity, carbon dioxide level and other information. Also, in this project, we integrated the cooling monitor system. Display the vital data such as operating power, unit operating status, working conditions, and VRV（Variable Refrigerant Volume) system operating status of the water-cooled host.

Conclusion

In the era of rapid economic development, industrial parks (software parks, technology parks, logistics parks, etc.) are the important part of smart city development. Digital transformation is now the crucial need for industrial parks to upgrading towards to a smarter, greener city component.
