Abstract
Three-dimensional Visualization of Particulate Matter Data Focused on Metropolitan and Gangnam Station Areas in South Korea
Highlights
The urbanization process in most countries around the world has accelerated resulting from the increase in the influx of people to cities
The 3D Geospatial Grid Library, which was developed for the 3D visualization of particulate matter data, was constructed by combining the functions of open sources available on the Web
The concept of the 3D geospatial grid was introduced, and a 3D Geospatial Grid Library was built for 3D visualization
Summary
The urbanization process in most countries around the world has accelerated resulting from the increase in the influx of people to cities. The horizontal structure of cities has gradually become vertical owing to the limited space, advances in construction technology, and the efficient utilization of national land. Efforts have recently been made to create 3D spatial information because of the increasing importance of obtaining height information according to the changes in the physical environment. Three-dimensional spatial information overcomes the limitation of the abstractness of 2D spatial information and provides necessary information for real-world applications. The demand for such information has exponentially increased in the era of the Fourth Industrial Revolution.
