The Sloan Digital Sky Survey has created the most detailed three-dimensional maps of the Universe ever made, with deep multi-color images of one third of the sky, and spectra for more than three million astronomical objects.
Contains more than 71 thousand maps and images that span the 16th to the 21st century and illustrate everything from the seven continents, to the entire world and even celestial bodies. The maps and images serve as useful historical and artistic references, offering rare cartographic detail and insight into the visual organization of territories. The exceptionally high-resolution images can be filtered by place, author, and date of creation.
structured map of the World: share any place, ruler, address search, cities lists with capitals and administrative centers are marked. Plan with streets and roads, states and regions boundaries, streets panoramas etc.
