Account Options Sign in Earth at Night 2012 This new global view and animation of Earth’s city lights is a composite assembled from data acquired by the Suomi NPP satellite. The data was acquired over nine days in April 2012 and 13 days in October 2012. It took 312 orbits to get a clear shot of every parcel of Earth's land surface and islands. ©2014 Google - Terms of Use Layers Map

25 National Flags And Their Meanings Originating on battlefields as a means of identification, national flags have come a long way since their bloody conception. Flying in courthouses, classrooms, and fire stations they typically hold symbolic significance for the nation and have complex meanings ingrained into their designs. So go ahead and test yourself on your flag knowledge because these are 25 national flags and their meanings.

Google Vector Layers - Jason Sanford There’s no shortage of geo data providers these days. It’s quite easy to publish data and make it available to the world in minutes using software like ArcGIS Server, Geocommons, Arc2Earth and CartoDB. What’s sometimes not easy as it could be, is taking data from these providers and showing them on your slippy map of choice, Google Maps. For the past few months in my downtime I’ve been working on a library that makes it much easier to view and interact with your data in these services — Google Vector Layers. With just a few lines of code you can view data from a number of geo web services, symbolize it based on property values and create highly customized InfoWindows using the feature data. The library works by listening to map events (pan and zoom) and then fetching features within the map’s extent after each event.

The Nighttime Earth SAN FRANCISCO — The Earth at night looks more beautiful than it ever has before in these incredible new images from NASA's Suomi NPP satellite. These super-high-resolution images, made possible by a new type of infrared sensor on the satellite, were revealed here at the American Geophysical Union conference Dec. 5.The Visible Infrared Imaging Radiometer Suite has a "day-night band" that can detect natural and man-made light with unprecedented resolution and clarity. It can resolve everything from the nocturnal glow of the atmosphere to the light of a single boat at sea. It can detect auroras, wildfires, the reflection of moon and star light off clouds and ice and the lights alongside highways. The sensor has six times better spatial resolution and 250 times better resolution of lighting levels than anything that came before it.The VIIRS instrument works by scanning in 22 different wavelength bands.

Enhanced Geothermal Systems The energy from the heat beneath the earth's surface is essentially an unlimited resource. What if it could be developed to help solve our energy challenges and fight global warming? Enhanced Geothermal Systems, or EGS, attempts to do just that. EGS produces heat and electricity by harnessing the energy from hot rock deep below the earth's surface, expanding the potential of traditional geothermal energy by orders of magnitude. EGS is a big challenge, but with the potential to power the world many times over, it demands our immediate attention. At Google we support efforts to advance EGS through R&D, investment, policy and information.

40 Maps That Will Help You Make Sense of the World If you’re a visual learner like myself, then you know maps, charts and infographics can really help bring data and information to life. Maps can make a point resonate with readers and this collection aims to do just that. Hopefully some of these maps will surprise you and you’ll learn something new. A few are important to know, some interpret and display data in a beautiful or creative way, and a few may even make you chuckle or shake your head. If you enjoy this collection of maps, the Sifter highly recommends the r/MapPorn sub reddit.

South Sudan, Welcome to Google Maps South Sudan has officially existed as an independent country since July 9. Now it also exists on Google Maps. The absence of South Sudan on Google Maps, and the majority of Internet maps, has frustrated citizens of the new country. Top 60 Chinese Cities Cities are one of the many phenomena that follow a long-tailed distribution. In simple terms there are a few big cities and lots of small ones. The classic way of showing a long tailed distribution (and the method from which the name is taken) is to produce as plot such as that below: The infographic at the top of the post by demonstrates the distribution in a more engaging and constructive way. One method I have used in the past to demonstrate data with a long tailed distribution is the excellent Wordle tool.

40 maps that explain the world Maps can be a remarkably powerful tool for understanding the world and how it works, but they show only what you ask them to. So when we saw a post sweeping the Web titled "40 maps they didn't teach you in school," one of which happens to be a WorldViews original, I thought we might be able to contribute our own collection. Some of these are pretty nerdy, but I think they're no less fascinating and easily understandable. A majority are original to this blog, with others from a variety of sources. I've included a link for further reading on close to every one. Inspirations from Maths Three Spheres I Based on another famous and simple Escher print. Here we find a kind of “multi-level game”, since what appears to be a sphere is actually a flat circle with a print of a reticulated pattern that simulates the volume of the sphere. To make clear the “game” Escher represents the same sphere (a flat disk, in fact) placed in various forms: vertically, stretched and folded in half.

Early world maps Antiquity Babylonian Imago Mundi (c. 600 BCE) A Babylonian world map, known as the Imago Mundi, is commonly dated to the 6th century BCE.[1][2] The map as reconstructed by Eckhard Unger shows Babylon on the Euphrates, surrounded by a circular landmass showing Assyria, Urartu (Armenia)[3] and several cities, in turn surrounded by a "bitter river" (Oceanus), with seven islands arranged around it so as to form a seven-pointed star. The accompanying text mentions seven outer regions beyond the encircling ocean. The descriptions of five of them have survived:[4]
