Message of the map: figure out what are the high density population areas in the US.
Why would I use 3D? it looks more appealing, the user is excited to explore the map in 3D
Additional problems in 3D:
- harder to navigate
- solution: navigation widgets; much more intuitive using touch navigation!
- hard to compare heights
- solution: mapping the same variable on both color and height;
Further problems: - color is distorted by the lighting settings
- solution: could we have the sun move with camera position? choose color schemes where the colors are quite different
- height is distorted by perspective
- solution: setting a smaller field of view helps to view elements in an isometric projection
- solution: mapping the same variable on both color and height;
- very low resolution on a retina display
- solution: fix in the API
- quite slow because of the amount of data
- solution: ...
- no way to view county borders? have to think about a workaround...
