Geospatial Analysis in CoViz 4D
- satellite and hyperspectral imagery
- buildings (footprints / rooflines)
- vehicle / traffic information
- roads and infrastructure
- hydrological information
- wildlife areas and other envelopes (e.g., air space restrictions)
These diverse data streams are typically derived from disparate sources and CoViz 4D includes automated workflows for reading many industry-standard, third-party data formats and integrating them in a common visual and analytical environment.
A nearly one-billion-point dataset of the Canadian city of Ottawa is shown in impressive detail, and can easily be manipulated and interrogated in CoViz 4D. Contains information licensed under the Open Government license, Canada. Imagery provided courtesy of Digital Globe.
Once the surface scene is constructed in CoViz 4D, quantitative analysis of the objects in the scene is achieved through numerous built-in tools. For example:
- The slope and aspect of ground terrain can be calculated to assess drivability during ground operations or the safety of potential aircraft landing zones.
- Distances between objects can be calculated, such as from a building to a road or an aircraft to a building, and these distances can be updated in near real-time to provide a clear visual assessment as conditions change.
- Routes can be planned on-the-fly in the interactive visualization environment and missions rehearsed prior to execution.
- Using a special visualization mode, the user’s eyepoint can be transferred to a moving object, for example, to obtain a pilot’s eye view during an airborne mission.

ARTICLES & PAPERS
Hesham Ebaid, Kanglin Wang, Marcelo Seixas, Gautam Kumar, Graham Brew and Tracy Mashiotta examine enhanced workflows and solutions for optimizing the utility of Permanent Reservoir Monitoring data in a deepwater setting.
Graham Brew, Dynamic Graphics, Inc., USA, and Jane Wheelwright, Dynamic Graphics, Ltd, UK, discuss the integration of 4D seismic data into the reservoir management workflow.
A solution that offers a dynamic, temporal visualization environment for data fusion and integrated reservoir surveillance.
Dynamic Graphics has developed a tool which can visualize multiple datasets from an oil field simultaneously in 3D and 4D—from an overall view of the basin to a view of the individual wells and reservoirs—and you can see how it changed over time as well.
