Last twelvemonth Jacob Wasilkowski released an interactive map which visualized Nasa’s nighttime lights information equally as elevation data. In other words the Earth at Night map shows lite pollution simply about the public inwards 3D equally mountains of light.
NASA's hence called Black Marble map is made past times combining the best cloud-free satellite images of every province majority expanse of the Earth. The upshot is a map which shows the distribution of artificial lights simply about the world. Jacob has used NASA's information on lite pollution to practice an interactive map of the public which shows the brightest areas equally high peaks together with the darkest regions equally valleys together with plains.
Jacob has similar a shot released a 'how to' guide explaining how he created the map. Obviously converting NASA's lite pollution map into a 3D elevation map includes a release of steps. One of these steps was to operate chroma.js to convert every lite pixel on the Black Marble map into a release range, which could together with hence hold upwardly used to visualize the luminosity values equally elevation heights.
Using the metaphor of elevation is becoming a pop method of visualizing information on 3D maps. We've seen this close of late on the Pudding's Human Terrain interactive map. The Pudding's map shows population density across the globe using 3D population pyramids. The taller a pyramid block on the Pudding map together with hence the higher the population.
