Unique Visualization


I was intrigued by the aerial image visualization on the site. A screenshot of it is provided above. Its actual location is at the following link: http://www.ittc.ku.edu/wlan/index.shtml. The site also describes this project--how the designers used aerial photography and interpolation techniques to visualize wireless signal strength. As a person with remote sensing imagery background, I find this visualization particuarly interesting since it functions as both a map and as an image. I like the straightforward color scheme, and the transparancy effect so that you can see the ground underneath. It symbolizes the invisible nature of a wireless signal quite well. With the street labels and detailed image basemap, it would be easy to use as a reference map to find the best place to get a signal.

However, it also has some flaws, notably that it does not precisely state the location of the map. I will assume that it is in Kansas somewhere because of who made the map, but I can't be sure without it mentioned. Also, the color scheme would probably not work for multiple wireless towers since it would likely create a cluttered map with too many contrasting colors. While it works well showing one, it would probably not work well when showing many in a small space. Lastly, the designers could have moved their watermark/label to the bottom of the map. While I can see they want the credit, its current location distracts the viewer and makes it difficult to focus on the map. Either shrinking it down, or moving it to the lower-left corner away from the legend would help.
