“New research on how bees perceive colour could be put to good use in our digital cameras, meaning photos shot by drones or phones would look more natural than ever. It’s all to do with colour constancy, the way that bees (and humans) can tell a flower is red no matter what the colour or quality of the light – a mental trick that the digital cameras of today really struggle with.”

At DigitalGlobe we spend a great deal of time focused on urban areas, where the majority of the world’s people now live, and thus where the majority of commerce, conflict, and change take place. Earlier this year an interesting thought crossed my mind: “What would a perfect city look like from space?” Would it have large open venues or lots of public transportation? Would there be an abundance of parks or the tallest skyscrapers in the world? How would this vision of idyllic urban design change depending on where in the world you were?

In many neighborhoods, income’s influence on a neighborhood can manifest itself physically in different ways.  Well paved roads and better maintained buildings are just two signs of a wealthier neighborhood.  The amount of vegetation, even in densely urban areas, can also be a predictor of the relative wealth of a neighborhood.  Known as the “gray-green divide”, the amount of trees and green space can be an indicator of the income level of the neighborhood.

What is the Gray-Green Divide?

The gray in the phrase, “gray-green divide”, refers to the dominant color from roads, sidewalks, and rooftops that strikes the viewer when looking at an aerial or satellite image of a lower-income neighborhood.  In contrast, higher-income neighborhoods tend to have more vegetation in the form of trees and landscaping that provide a “greener” view to the imagery.  The disparity is even more evident when viewing a lower-income neighborhood that back ups to a wealthier one.
