  1. Implementation of a geographic information systems (GIS)-based system
    to evaluate the visual impact of offshore renewable energy installations

    The United States Department of Interior's Bureau of Ocean Energy
    Management (BOEM) faces increasing interest in the use of waters under its
    jurisdiction for offshore renewable energy development. The Visual Impact
    Evaluation System for Offshore Renewable Energy, or VIESORE, is a GIS-
    based application which allows BOEM staff to import or interactively design
    the spatial layout and content of an offshore facility, import and prepare
    geospatial data that will affect visibility, run a series of visual analyses which
    take into account earth curvature, define atmospheric, lighting and wave
    conditions and, finally generate one or a series of realistic visualizations from
    multiple viewpoints.
    Introduction Requirements
    Approach System design
    Development to date Current results
    · Enable spatial design of offshore facility
    · Import geospatial data
    · Allow user control of atmospheric, lighting, and wave conditions
    · Generate spatially accurate and realistic visualizations
    · Output reports and images
    · Provide a user-friendly interface
    3D visualizations through a customized familiar
    GIS interface
    Renders Reports
    AVI
    HTML
    · Vue Infinite 10 3D modeling software accessed in background batch
    mode through Python programming language via customized, yet
    familiar Esri ArcGIS interface
    · Vue provides photorealistic renderings
    · User sets up real-world project data in ArcGIS interface, all data and
    settings get passed to Vue where visualizations are then created
    · Users familiar with ArcGIS interface – this eliminates need to learn
    Vue 3D software package
    ArcGIS code 3D modeling

    GIS data inputs
    Custom
    ArcGIS
    tools
    ArcGIS 10
    · Import GIS data into Vue 3D visualization program
    · Import wind turbine generator 3D models
    · Set camera and sun positions
    · Render to image (jpg)
    All done in
    background via
    custom Python
    code
    · Creation of photorealistic visualization renderings of planned
    offshore renewable energy installations
    · Successful import of real-world GIS data into Vue 3D software
    package for use in visualizations
    · User provided with friendly interface which allows them to import
    data

    The system must:
    · Independently evaluate visual impact of proposed facilities
    · Validate photomontages provided by vendors
    It shall enable users to:
