Following on from the population analysis I published yesterday estimating quantitatively how many people live within certain distances of each of the world’s nuclear power plants, some people have asked me for more information on population distribution itself, and whether it might provide more spatial context for the results of the analysis — for example is the plant close to urban sprawl from a major city. Or why is it that nuclear power plants in France, for example – which with 58 nuclear reactors, is second only to the United States (which has 104) in terms of numbers of nuclear reactors — tend to have fewer people living near to most of them, compared with, for example, much smaller nuclear power nations such as Germany?
So to try provide some more visual geographical context, today I’ve mashed together the results of the analysis I published yesterday in Nature — see here my 3D map of the results of that analysis — with a new very high-resolution global population density Google Earth map for 2010 created by the NASA Socioeconomic Data and Applications Center operated by Columbia University’s Center for International Earth Science Information Network (CIESIN). The underlying data is the same as we used in our previous analysis.
Mashing the two maps together certainly does provide this sort of greater context, but the result of combining them is also a bit visually overwhelming, and may be confusing at first. — so beware.
Here’s a screenshot — you can find the full 3-D interactive mashup of the two maps below the fold.
