Visualization Concepts for Generating Insight from NAS Simulation Data

representation, based upon the existing NAS hierarchy. The NAS is divided into 20 “En route” zones, covering the continental US. These “En route” zones are large regions of space with names like ZLA (around Los Angeles) and ZFW (around Dallas-Fort Worth). We can map these 20 en routes zones into a 5x4 array (see Figure 3). For a 1280x1024 display, we can allocate 250x250 pixels to each of the squares in this array. Each “En route” zone is divided into an average of 40 sectors. These sectors are grouped into three categories of altitude: Low, High and Super sectors (listed in ascending order). For each “En route” zone square, we divide it into those three altitude groups and dedicate a box for each sector. In each box, we can render a glyph, showing congestion in orange and delay in blue (Figure 4). While this is a particular glyph to show the correlation between delay and congestion, this visualization concept could use any other glyph design to show other desired NAS properties in each sector.
