Web GIS & Drone Photogrammetry Bring Benefits to Smart City Management hightopo Just now·7 min read

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

Oblique photography

• 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

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.
