Modeling & Visualization

Modeling and visualization have become important tools for communicating proposed improvements to roadways and other facilities beyond the engineering plans and 2D representations that the public does not always easily comprehend. Leveraging applications available from the video game and architecture industries, we are able to communicate visually more quickly and accurately than ever before. Historically, the scale of transportation projects and the multitude of CADD platforms in the industry created challenges. Isthmus team members have embraced those challenges to develop higher-quality and more interactive models in very efficient timeframes.

Our team starts with a combination of items including a 3D design model, field collected data, and ortho-imagery or photogrammetry collected via drone. These items are then compiled through a variety of visualization rendering software that provide photos, videos, 360-degree panoramas, and virtual reality tours that layer together proposed work with current, actual images from the surrounding landscape so viewers can relate more directly to their location.

For visualization earlier in the planning and conceptual stages, our rapid 3D visualization process allows our team to create models even more efficiently. These models can be updated throughout the design process to support analysis and facilitate decision-making.

We have presented our models to customers and the public for a variety of needs including design, plan production, and engagement. The models have consistently received very positive feedback from everyone, both clients and members of the public.

Drone Imagery
Isthmus owns two drones, a Mavic 3 and a Phantom 4 Pro V2.0, and two team members are licensed drone pilots. The drones are used for capturing aerial images and videos to create 3D photogrammetric models.

3D CADD Modeling
Our team uses both Bentley and AutoCAD products for civil engineering design. 3D modeling is built into our design process from conceptual through preliminary and final roadway designs, as well as for public involvement activities.

Image/Video Rendering
We use a variety of platforms to create animated objects and people, and realistically textured roadways and landscapes that can then be used in virtual reality environments.

Rapid 3D Visualization Process
Our team has developed a rapid 3D visualization process that can create photorealistic models more quickly and nimbly. This process is ideal for complex designs that are difficult to convey, alternatives analysis, and quicker turnaround projects. The models can be tailored for their purpose to accurately convey details from conceptual, through preliminary to final design for stakeholder decision-making and public engagement. The 3D models are able to be iteratively updated to show design refinements and decisions as the project development process evolves.
