  • Seeing is BelievingUse of 3D Visualizations in Planning Projects

    Gordon W. Perkins, ESS Group, Inc.

  • Purpose and Intent

    To explore the visual impact assessment process and available technologies in visualization.

    Why

    Visual impact is a subject often overlooked in development, thus areas are a risk of losing their identities. While visual impact is subjective topic, most people agree on what makes a place beautiful. The challenge comes when identifying what activities might compromise that beauty.

  • The steps in assessing visual impact:

    1. Identify Resources

    State and Federal governments are digitizing their records at a frantic pace in order to establish an archive and capitalize on cooperative efforts.

    Most data are getting more accessible so consultants and stakeholders alike can access and view pertinent information.

    The steps in assessing visual impact:

    2. Establish regional visibility

    Because a project is visible does not mean it results in visual impact. However, not visible does mean no visual impact. So we begin with a process of elimination.

    Further ZVI refinement through the inclusion of vegetation and structures. Point cloud LIDAR makes an

    incredibly accurate visibility prediction model.

  • The steps in assessing visual impact:

    2. Establish regional visibility

    Line of Sight Cross Section Analysis is useful in assessing how topography, buildings and vegetation define

    views from individual locations.

    Line of sight analysis should be used sparingly as it is limited to one view and one direction.

  • The steps in assessing visual impact:

    2. Establish regional visibility

    Ballooning was the tried an true method for developing simulations, but it now has a renewed purpose in VIA.

    Drone technology is next.

  • Resolution requirements (why sensor size is important). Lens settings Geo-locating camera and reference points

    The steps in assessing visual impact:

    3. Document visibility

    Photo documentation may be one of the most critical (or at least the most criticized) processes in visual impact assessment.

  • HDRI - up to 54 photographs to document a single view Panoramas - A deceiving technology if used incorrectly. (40 vs. 124)

    The steps in assessing visual impact:

    3. Document visibility

    Documenting context and innovations in gigapixel technology.

  • Historic and cultural sensitivity Users Frequency and concentration of use Stakeholder and official input (federal, state, and local level contribution) Recreational resources Federal, State and local resources Designated scenic areas

    The steps in assessing visual impact:

    4. Select Representative Views

  • The steps in assessing visual impact:

    5. Create Simulations

    Model the proposed action with adequate detail 3D align the photographs in georeferenced space Place existing elements in the scene Model the ground plane as proposed

    Add the project in georeferenced space Add environmental variables Render the view 2D Finalize
