3D scene building, based on open-source digital terrain models, buildings, vegetation, powerlines, fences and satellite images can be integrated for visual communication and analysis functions for a multitude of purposes. CoViz 4D is extremely adept at quickly building 3D and 4D ‘fit for purpose’ data environments
With the development of geographic information systems (GIS) in recent years, there has also been advancement in terrain exploration and visualization technology. Terrain exploration plays an important role in areas including geology, aviation, meteorology, and archaeologywhich require a large amount of topographical and geospatial data for scene analysis. The oil and gas industry also uses terrain data to get a birds-eye view of the field for exploration and infrastructure planning. This exploration and scene analysis can be further enhanced with visualization.
3D terrain visualization software can be used to easily integrate the different terrain data into a comprehensive 3D simulation model. Through visualization, the topographical, geospatial, and temporal data can be better understood and analyzed.
The Role of 3D Terrain Data
In a more traditional method of 2D surface modelling, although there are methods such as contour mapping, it is a challenge to communicate the distance and elevation features of obstacles like hills or valleys. The 3D terrain modeling attempts to eliminate this challenge with the integration of topographical as well as geospatial characteristics. The topographical characteristics comprise terrain obstacles such as mountains, ridges, or valleys. Geospatial characteristics represented in the model may include objects or location information such as the presence of buildings, roads, trees, or powerlines, as well as temporal phenomena such as weather or climate conditions.
3D terrain modeling allows the integration of these topographical and geospatial data sets for successful scene analysis. The integrated datasets may include LiDAR data, structural and property models, digital elevation models, satellite imagery, infrastructure locations, InSAR data, and many more. These data can be generated using various digital sensing methods. LiDAR, for example, is a remote sensing method, which emits laser beams to the ground to detect obstacles and provide excellent elevation point measurement.
With 3D terrain modeling and visualization software, these data can be mapped and simulated with ease and efficiency. The model can be used by decision-makers to analyze terrain features, plan field operations, and make critical project decisions.
3D Terrain Visualization Software for Scene Analysis
The multicomponent terrain data can be integrated to create a dynamic 3D terrain simulation model. The model can be used for general visual awareness as well as making critical decisions regarding applications such as land use planning, drainage modeling, urban planning, landscaping, oil and gas exploration, and many others. 3D terrain visualization software can help in the analysis by:
- Emphasizing terrain features such as structure, slope, and elevation
- Locating obstacles or barriers in the terrain
- Detailed analysis with scalable model and high-quality 3D imaging
- Ability to add a temporal factor to see changes over time
- Ability to store data for future reference
- Enhanced visual perception
- Easy interpretation with the use of imagery, texture, contours, and colors
- Easy modification of the model for any changes without the need to rebuild the entire map
Multi-component Data Integration and Visualization with CoViz 4D
Coviz 4D can be used to visualize a large volume of terrain data for scene analysis. The software integrates multi-component data that represent topographical, geo-spatial, and temporal features of the terrain into a single platform. The data sets from different public sources (including USGS) as well as personalized data (from drones) can be integrated to display a full picture of the area of interest. The advantage of using drone data is that it can provide up to the minute data for recent changes. CoViz 4D also offers temporal data integration with information on sundown, twilight, tides, and winds. This integration of multicomponent data assists in building a complete picture of the terrain.
For informed decision-making, CoViz 4D provides a clear and immersive 3D terrain model. This model can be used to analyze how the different data components will affect the activity and choice of equipment and infrastructure that might be required. This information is important in making critical exploration, design, or capital-related decisions.
