Google Maps gets “more detailed, colorful map”

Google Maps gets “more detailed colorful map”

Don’t be too shocked if Google Maps out of the blue begins wanting completely different quickly. Google announced a rework for the Google Maps regular map tileset which can now pull in shade knowledge 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 photographs within the gallery above.

The firm can be tweaking the colour palette for a extra vibrant map—ocean blues are bluer, forest greens are greener, and the map now even reveals snowy mountain peaks in white and barren land in brown. The world is a giant place, so after all, that is all taking place 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 approach, we’re capable of 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 approach work? First, we use computer imaginative and prescient to determine 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 color model. For instance, a densely coated forest may be categorized as darkish inexperienced, whereas an space of patchy shrubs may seem as a lighter shade of inexperienced.

Previously, the bottom map was solely ever gray (regular land), inexperienced (vegetation and parks), or blue (water). The massive addition is the coloring of filth and snow. It’s not precisely clear what is going on on with the conventional floor shade. Arizona is now very brown, which is smart as Google says it now “accurately reflects its desert landscape.”  But one other slide reveals Morocco and a piece of the Sahara Desert, however that is… nonetheless grey? It looks like there are nonetheless some bugs to work out.

Google says the brand new shade scheme is rolling out beginning this week.
