Do not be too stunned if Google Maps abruptly begins wanting totally different quickly. Google introduced a rework for the Google Maps regular map tileset which is able to now pull in colour information from satellite tv for pc imagery. Google printed just a few before-and-after comparability photographs, which we have aligned with the supply satellite tv for pc pictures within the gallery above.
The corporate can also be tweaking the colour palette for a extra vibrant map—ocean blues are bluer, forest greens are greener, and the map now even exhibits snowy mountain peaks in white and barren land in brown. The world is a giant place, so in fact, that is all occurring algorithmically. Google explains:
Google Maps has high-definition satellite tv for pc imagery for over 98 % of the world’s inhabitants. With a brand new color-mapping algorithmic method, we’re in a position to take this imagery and translate it into an much more complete, vibrant map of an space at world scale.
How precisely does this color-mapping method work? First, we use pc imaginative and prescient to establish pure options from our satellite tv for pc imagery, wanting particularly at arid, icy, forested, and mountainous areas. We then analyze these options and assign them a variety of colours on the HSV colour mannequin. For instance, a densely coated forest will be categorized as darkish inexperienced, whereas an space of patchy shrubs may seem as a lighter shade of inexperienced.
Beforehand, the bottom map was solely ever gray (regular land), inexperienced (vegetation and parks), or blue (water). The massive addition is the coloring of grime and snow. It isn’t precisely clear what is going on on with the traditional floor colour. Arizona is now very brown, which is smart as Google says it now “precisely displays its desert panorama.”  However one other slide exhibits Morocco and a piece of the Sahara Desert, however that is… nonetheless grey? It looks as if there are nonetheless some bugs to work out.Learn 1 remaining paragraphs | Feedback
