GIS, Visualization and Modeling Program

The complexity of large-scale datasets and new forms of born-digital scholarship demands new methods and tools that keep pace with contemporary research. The IDRE GIS, Visualization and Modeling program emphasizes the ‘spatial turn’ that is opening up new opportunities for discovery and innovation.

GIS

The impact of Geographic Information Systems (GIS) on research at UCLA cannot be overstated. Disciplines across the campus have embraced the technology to build knowledge within their primary fields and as part of inter-disciplinary teams exploring broad research themes and grand challenges.

Visualization

The term visualization encompasses a broad range of analytic tools and techniques that includes GIS, 3D modeling, and data and statistical visualizations. The common thread is the underlying desire to organize date into a coherent visual display that can be readily interpreted and understood.

Data visualization is the subset of visualization that involves the graphic display of data too complex for manual processing, and the resultant imagery is typically the end result of an algorthmic process or generated from a large-scale dataset. Prime examples of this type of visualization done through the IDRE-HPC team include 100K DLA simulation, laser simulation, fluid simulation, and network analysis.

Statistical visualization originates from the statistical analysis of datasets and is supported by the combined forces of IDRE’s Stats Group and GIS, Visualization and Modeling team.

Modeling

At IDRE, 3D computer modeling is considered a subset of visualization that involves the generation of geometry either manually, from data, or from a scanning process.

  • Real-time simulation, where the output focused on highly detailed large-scale virtual worlds explored interactively; the NEH-funded VSim software supports pedagogical use for academically generated 3D content (Creator)
  • Photorealistic rendering, where output is focused on single-frame static imagery or fixed animations (Maya, 3DStudio, Rhino)
  • Web-based interaction, where output is focused on online user interaction, online virtual worlds, and game packages (Sketch Up, Google Earth, SecondLife, Unity)
  • 3D object scanning, where geometry is captured from 3D scanning rig (rather than constructed) for manipulation
  • Terrain modeling, where geometry is generated from GIS coordinates or satellite imagery for large-scale research questions of natural environments
