![]() This long tongue of ice in Alaska's Prince William Sound is one of the fastest-moving glaciers in the world thanks to rapid warming in the far north. But does Wyoming coal have a future in a climate-conscious world? The Powder River Basin produces more than 40% of America's coal, and the land bears the scars of all that mining. As the Arctic warms, will glaciers become a thing of the past? Is the economic benefit worth the environmental cost?Ī warming climate has helped cause this Alaskan glacier to retreat by nearly 2 miles over the past few decades. The once quiet forests of northeastern Alberta have been transformed by the boom in unconventional oil. ![]() The financial capital of China was always a major city, but over the past 30 years it has metastasized across the Yangtze River Delta, building skyscrapers over what were once farming villages. Once little more than a fishing village, this Middle Eastern megacity has blown up in recent years, even extending onto new land in the Persian Gulf. These images were more “accurate” since the area started rebuilding.The city has exploded over the past few decades, sprawling into the desert-even as a growing population and worsening drought shrink nearby Lake Mead. They later restored photos of the city from before the disaster. ![]() Google had updated the city right after the disaster. Sometimes slightly older images are considered more accurate, as in the case of post-Katrina New Orleans. Sometimes they use slightly older images and set the up-to-date ones in historical imagery. Google doesn’t always put the most up-to-date imagery in the app. This thought may sound strange, but check “historical” imagery to catch more recent shots. If you’re disappointed with your Google Earth view and are hungry for more up-to-date data, there may be more available, and you’re just not looking at it. If they entertained every request, their schedule would crumble. Google has a system for keeping the images as current as reasonably possible. Unless you’re a governing body that has compiled a package of aerial images to share with Google, they are unlikely to heed a request for an update. Will Google Earth update imagery upon request? So if your town had an update last year, and you’re still waiting to see the new stadium built in the past six months, you might be waiting a while. Although, they are likely to target high-density population areas more frequently. They strive to keep each area of the globe within three years. Google would have to constantly hire pilots traversing the globe to keep up with potential changes. Both take time to obtain and implement, and aerial photos are relatively expensive. Google Earth FAQs Why doesn’t Google Earth Update Continuously?Īs previously mentioned, Google Earth combines satellite images and aerial photographs. After all, the Earth is a prominent place. While this situation is inconvenient, it is understandable. Given the intense effort required to systematically catalog and piece together all the images needed for Google Earth, it’s no wonder it takes years to update. When Google releases an update, they also release a KLM file that outlines the updated regions in red, letting everyone know what got changed and what’s still waiting for a refresher. A single Google Earth update might contain a handful of cities or states. Google does not update the entire map in each go. If you’re anxiously awaiting an update on your hometown, don’t assume it will appear in Google’s subsequent changes. What Does Google Earth Update?Īh, there’s the rub. There are only so many satellites taking pictures in space, among other places, that Google can use for this project. This duration range is understandable given how many photos are required to create Google Earth. In fact, the average map data is between one and three years old. However, this doesn’t mean that every image is updated every month. According to the Google Earth blog, Google Earth updates about once a month.
