   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

   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:
