Abstract or Summary
  • ArcView 3D Analyst is a powerful geospatial tool, and has proven very useful in 3D visualization and analysis. In most cases, 3D data models are temporally static, representing only one instance in time. For many applications, the 'missing' time dimension is of great significance, and there is a need to incorporate this fourth dimension into data visualization techniques. This paper discusses a method, designed by the author, of realizing fourdimensional or time-sensitive visualization of data. The method utilizes ESRI' s ArcView 3.2 ® software, and integrates the surface generating ability of Spatial Analyst ®, the 3D visualization power of 3D Analyst ®, and the data compression and high quality graphics of Adobe's LiveMotion ® to generate high quality animation files accurately depicting changes in 3D space over time. This paper will examine the development of this method and will showcase the manner in which it was applied to two different data sets: ground-water modeling and aerial dispersion modeling. Finally, the paper will discuss the challenges presented by this method, the limitations a user encounters, and possible directions for future work using this method of 4D data visualization.
