3D City Modeling
Definition
3D City Modeling is a digital representation process that aims to replicate a city or urban environment's real-world physical characteristics in three dimensions. The modeling can encapsulate various scales ranging from individual buildings to the entire city landscape, including various infrastructure elements like roads, buildings, and water bodies. It utilizes Geographic Information System (GIS), Remote Sensing (RS), and Computer-Aided Design (CAD) technologies to create visually realistic and spatially accurate models.What is 3D City Modeling?
3D City Modeling is a sophisticated simulation technique that helps visualize urban landscapes on a virtual platform. These models provide a comprehensive view of an urban area by incorporating height data and texture information to represent the real-world scenario accurately. The models can be constructed from various sources, including satellite imagery, aerial photographs, laser scans, or existing CAD plans.Three crucial components form the basis of 3D city modeling: data collection, model construction, and model rendering. The data collection process includes capturing specific geographic data points using various methods, such as LIDAR or photography. Model construction is where the captured data gets transformed into a 3D model, and model rendering is the final process that creates the visual presentation of the model.
3D city models find extensive application in urban planning, disaster management, architectural designs, environmental studies, augmented and virtual reality, and gaming. These models also assist in telecom network planning, real estate valuation, solar potential assessment, and helping navigation applications.
