We used a screen-capture program at 5-minute intervals to take images of the three applications<br />

(two TVWs, one Google Earth) as the live radar data were streamed to them. The time stamp of<br />

the last radar scan is visible in the screen captures at the bottom of each TVW display <strong>and</strong> at the<br />

top of the Google Earth screen. The reference (workstation) time is also visible in the lowerright<br />

corner of each screen capture. This layout is shown in Figure 6-102.<br />

We maintained consistency in the color-coding of the tracks from the two radars among the<br />

TVW displays <strong>and</strong> the Google Earth COP. Tracks from the SEAAR2u radar at SEA were<br />

displayed in red, while tracks from the SEAAR2l at SEA were displayed in yellow, as seen in<br />

Figure 6-101 <strong>and</strong> Figure 6-102.<br />

We used a Microsoft Excel® workbook to record all four timestamps <strong>and</strong> the local (reference)<br />

time from each screen capture. We calculated the latencies as the difference between the local<br />

reference time <strong>and</strong> the corresponding TVW <strong>and</strong> Google Earth timestamps.<br />
