Visualization of terrain surface finds many applications indifferent area of earth sciences, GIS, and geomatics. With advent of advanced computer graphic algorithms and their HPC implementation through GPU, realistic and high-fidelity visualization of terrain surface is possible. Geographic Information Science (GIS) has made considerable strides since the introduction of 3D terrain visualization facilitating accurate visualization, analysis and measurement of geospatial events and attributes. This paper discusses the significance of different terrain visualization techniques with a special emphasis on 3D visualization.
How 3D terrain visualization is useful in photogrammetry, LiDAR, and aerial imagery, maps can generate detailed models of terrains, buildings, and objects. These techniques enable users to explore geographic features from various angles, zoom in for detailed analysis, and even simulate virtual environments. The applications of 3D maps are diverse and far-reaching. In virtual reality, they can create immersive environments for training, simulations, and gaming. In remote sensing, they aid in understanding natural resources, urban planning, and disaster management. In scientific visualization, they enable researchers to analyze complex spatial data and model real-world phenomena. In GIS, 3D maps enhance spatial analysis, decision-making, and communication of geospatial information.
In conclusion, the evolution of 3D maps in GIS has revolutionized how geographic information is visualized and analyzed, with potential applications in various domains. Advancements in technology continue to drive the development of 3D maps, transforming how we perceive and interact with spatial data, making it more realistic and meaningful.
