There exists many meth­ods for geo­vi­su­al­iza­tion of spa­tial phe­nom­ena. As talked about a few weeks ago, pop­u­la­tion den­sity can be mapped out using car­tograms, or by other more clas­si­cal meth­ods, such as the chloro­pleth and dot den­sity tech­niques. Another method is shown below, whereby pop­u­la­tion den­sity is explored as a 3-dimensional poly­gon extru­sion. This has been com­pleted using Arc­Globe with ESRI basic world population-by-state data. Have a look at the video below! Con­tinue reading »
